After the first PVC window profile was developed in the 1960s, the triumph of these windows took its course in Europe, and more and more classic windows were replaced by PVC models.
Following their decades-long success in Europe, PVC windows have also become increasingly popular in New Zealand.
We explain everything you need to know about the window material.
Affordable in every shape
The scientific name for PVC is polyvinyl chloride. The material is highly suitable for window profiles because of its excellent thermoplastic properties and resistance to the elements.
PVC can be formed into almost any shape by heating. Due to this good formability, even individual frame shapes such as triangular or round windows can be created.
Since PVC is easy to process, the production costs for PVC windows are significantly lower compared to other window types made of wood or aluminium. As a result, you can get PVC windows at a reasonable price.
Excellent thermal insulation
The so-called multi-chamber profile gives PVC windows exceptionally high thermal insulation values.
The small chambers in the material are visible in the profile cross-section. These small cavities break up thermal bridges, transmitting much less heat than filling material.
The rule of thumb for PVC windows is that the more chambers there are in the profile, the better the heat protection for your home.
Easy maintenance
Maintaining a PVC window is particularly easy as the material is highly resistant to the elements and does not corrode, swell or rust.
Another advantage is that, unlike wooden windows, PVC windows do not require regular repainting as these window frames are highly weather-resistant.
Only regular cleaning with gentle household detergents is required to maintain the windows. The best cleaning advice is to rinse the surface with warm water, gently wash it with a pH-neutral detergent and a soft cloth, and then rinse repeatedly with warm water.
Since PVC windows are particularly resistant to environmental influences, they are very durable. Therefore, if you take care of your windows accordingly, you will benefit from your PVC windows for a lifetime.
Unique colours and surface protection with acrylcolor
In addition to the energy-related advantages, PVC windows also offer a great choice of colours.
An enhancement with acrylcolor will add a unique design accent to your house facade and significantly further increase the durability of your windows.
Windows with acrylcolor require very little maintenance and are extremely easy to care for. The silk-matt, smooth and pore-free surface is insensitive to dust and dirt build-up. Therefore, peeling, chipping, and repainting are not required.
Acrylcolor is created in a so-called co-extrusion colouring process. This process enhances and protects PVC window systems in a long-lasting fashion. The white PVC base body and the coloured acrylic glass are permanently connected. As a result, the surface of the acrylic glass is inseparable from the primary body, giving PVC windows a long-lasting finish and extra protection.
The fusion of the two materials creates a satin-matt outer acrylcolor surface that can withstand any weather condition for decades to come. The colourful acryl coating is exceptionally durable and provides the window with high resistance against scratches and the effects of the weather.
UV Radiation Levels in New Zealand
Despite their decades-long proven durability worldwide, there are still some misconceptions about PVC windows in New Zealand. Most predominantly, it is said that PVC windows may not be suitable for the high UV radiation we experience here in New Zealand.
However, PVC window systems have been used internationally for many years in climates with greater weather extremes and higher UV radiation than those we are experiencing in New Zealand.
A comparison of irradiation maps of Europe and Oceania shows that the solar irradiation in New Zealand is comparable to those in Spain and Italy. In some areas in Spain, solar irradiation is even higher than in New Zealand. Still, these PVC windows are in perfect condition decades after their installation.
The internationally accredited Tropical S Severe Climate certificate proves that the PVC material of our windows withstands extreme and higher UV radiation levels than those in New Zealand.
Titanium Dioxide for Ultimate UV Resistance
The resistance of PVC windows is primarily guaranteed by using calcium-zinc stabilisers and titanium dioxide.
Titanium dioxide is a versatile substance used in many outdoor products continuously exposed to the elements. Its many useful features include refractive properties, robustness and colour vibrancy, making it an ideal additive for PVC window profiles.
In addition to being naturally resistant to the elements, titanium dioxide exhibits good UV absorption and light scattering properties. Therefore, when titanium dioxide is incorporated into the synthetic resins of PVC, it ensures that UV rays can’t penetrate and damage the product and its appearance.
This protection from weather, heat and UV damage is crucial for building materials such as windows, as they are expected to last for decades.
PVC Recycling Process
Today PVC windows can be almost entirely recycled. With professional disposal, old windows are added to the recycling cycle and can be used to manufacture new window profiles.
ECOWINDOWS PVC windows are manufactured with a high proportion of recycled material and are fully recyclable at the end of their life span. Old PVC is processed and converted to pellets, which allow it to be reused without loss of quality or material structure.
An old PVC window can be processed multiple times while keeping the same quality.
Conclusion
Windows made of PVC undoubtedly convince with a favourable price-performance ratio.
Their affordability, high thermal insulation values and the selection of colour designs of acrylcolor make PVC windows one of the most popular window materials.

Unfortunately, many people living in New Zealand regularly experience moist and foggy windows inside their houses. This moisture on the inside of a window pane is typically caused by improper ventilation, poor building standards and low insulation values of the building components.
Something most people might not have seen so often is a fogging that occurs on the outside of a window.
If we see any fogging on thermal insulating glazing, the alarm bells will quickly ring. But in this case, the concerns are unfounded: A fogged-up window from the outside is completely harmless and even a good sign.
Why do windows fog up from the outside?
You will only notice this phenomenon if you have installed triple-glazed windows with high insulation values. With this type of glazing, moisture condenses on the outside of the window pane during colder nights.
This occurrence happens because of the temperature difference between the air and the window surface.
The panes fog up, especially in regions with high humidity, where the air heats up faster than the window pane. This is because the heat-reflecting layer on the outer window pane reflects the thermal radiation from the room back into the room where it will stay.
High-quality thermal insulation glazing hardly conducts heat from the inside to the outside. As a result, the outer pane stays cold, promoting the formation of condensation.
Windows fogged up from the outside are a natural, physical effect and thus proof of quality insulating glazing.
Roller shutters prevent the glass pane from cooling down
Condensation on the outside of a window usually only occurs in the early morning hours and disappears on its own when the temperature rises.
However, if you are bothered by the fact that your view is clouded in the early morning, it might be worthwhile to consider the installation of roller shutters. These can effectively protect the pane from cooling down.
When you lower the roller shutter during the night, an air cushion forms between the window panes and the slats, and the stored heat prevents the window from tarnishing.

Like the rest of the world, we also have been following the developments in Europe with concerns in the past few weeks.
As an importer of European building solutions with many professional and personal ties, especially in Germany and Poland, we are affected by the current events – and we are so in two ways.
As a business, we are certainly impacted by the developments in Europe. In the last two years following the Covid pandemic, we have already experienced significant rises in energy prices and costs for transport and logistics. This trend will now most likely continue and intensify.
But as human beings, we are also personally affected and saddened by the damages this unnecessary war is causing. Our thoughts are foremost with the innocent civilians in Ukraine, who are suffering unimaginable tragedies and losses.
Nowadays, we live in a highly connected world. As a result, no matter how far away another country might be geographical, we will undoubtedly experience the effects of this war in one way or another.
What is ECOWINDOWS' reaction to the crisis in Europe?
Firstly, we are taking responsibility - for our customers.
We are doing everything we can to ensure our clients are not or, at least, only marginally affected by the current developments and will compensate potential extra costs as good as possible.
However, in the long run, we cannot rule out that orders, productions and deliveries may take considerably longer and, ultimately, prices for our products and their shipment to New Zealand might go up. Effects that, unfortunately, our customers and partners would also feel.
Secondly, we are also taking responsibility – as human beings.
Therefore, we support Doctors Without Borders and the UN Refugee Agency (UNHCR) to provide humanitarian relief efforts in Ukraine and its refugee crisis.
Our sincere thoughts are with the people of Ukraine these days.
What would an import ban on Russian oil to Europe mean?
Germany imports a third of its oil from Russia, which is the third-largest oil producer globally and the second-largest exporter. Many areas of our everyday lives depend on oil: transport, heating and production.
Following the war in Ukraine, oil prices have already risen sharply.
A ban on Russian oil means that almost everything would become more expensive: heating and driving, food that takes a lot of energy to produce. But also many other products like textiles, plastics and cosmetics.
Most notably, airlines, shipping companies and freight forwarders need oil for their transport. As a result, many products would also become more expensive due to these higher transport costs.
The consequences for industries and supply chains can be described as dramatic.
When an embargo stops the delivery of Russian oil to Europe, everything will become more expensive, and many small businesses will no longer be able to keep up. In a worst-case scenario, costs for the delivery of products, such as windows from Germany, will rise extensively.
However, we are preparing for all possible scenarios in this situation. Therefore, we are in constant and personal contact with our business partners in Europe to find the best possible solutions for all parties involved.
Also, many experts say Germany is much less dependent on Russia for oil than gas and coal. Numerous suppliers on the worldwide oil market could increase their production, at least in the medium term.
What’s the outlook?
Even though it is quite clear that it is impossible to replace Russia’s massive energy imports to Europe overnight, on a positive note, there still might be a glimpse of hope left in this rather grim scenario.
Remember that every crisis also brings great opportunities.
The current situation in Europe highlights our high dependence on fossil fuels, and, alongside that, also on other countries. There is a high chance that this crisis might raise greater awareness for renewable energy sources, sustainability, and potentially, in the long term, also a better building culture.
We are also getting a powerful reminder of the importance of peace and care for one another. And, despite the horrific situation, it is incredibly reassuring to see the flood of support from all over the world towards the people of Ukraine.
As the events unfold rapidly, we will keep you updated on the latest developments and their consequences for our business and our clients and partners.
During summertime and especially the holidays, we look forward to endless sun and long warm days on the beach. But these weather conditions might not necessarily feel so pleasant for us inside our home.
Unsurprisingly, windows play a crucial role in regulating the temperature inside a house, not only in the colder months but also in summer. If the sun shines unobstructed through the windows into the house, the heat can quickly build up and become very intense and uncomfortable, especially in peak summer times.
Therefore, we summoned for you several short- and long-term solutions that will effectively regulate the temperature inside your home when outside temperatures are high.
1) Short-term solutions
The following first two solutions can be implemented without any significant building alterations. Thus, there are no extra costs or investments required. The downside is, of course, that they are not long-lived and only deal with the symptoms of the heat, not solving the problem, to begin with. However, they can provide much-needed relief from the extensive summer heat during the peak season.
Keep Windows closed during the Day
This tip might sound strange at first, as opening your windows and doors is one of the most intuitive reactions to heat.
Understandably, there is a great temptation to let in a refreshing breeze when it is hot. But the effect is short-lived. Once it is warmer outside than inside, the heat creeps through the windows into the house. Therefore, it is best to keep the windows closed during the day when temperatures are high so that the warm outside air can’t flow in.
However, you can and should still ventilate your house in summer, but only in the morning or evening when the temperatures outside are not too extreme. In these times, you should open the windows to create a good draft.
Close your Curtains
Direct sunshine that enters through the windows can heat up your home significantly. Therefore, darkened rooms are one of the best ways to keep out the heat of the day.
Your curtains - especially those on the north-facing sides of the house - should be kept closed during the day. Light, opaque curtains are particularly suitable, as they reflect the sunlight better and heat up less than dark fabrics.
2) Long-term solutions
The above-described solutions help to lower the temperature temporarily to a tolerable level, but they are not long-lasting. As the unpleasant summer heat is a recurring issue, investing in more prolonged solutions to protect your home against high temperatures is worthwhile.
Install a Sun Shading System
Although curtains can help keep temperatures down inside the house, it is much more effective if sun protection is attached to the outside of the house in front of the window.
A professional sun shading system can create the perfect indoor climate and, with it, the ideal energy balance for your home. External venetian blinds, roller shutters and window awnings ensure pleasant lighting and atmosphere in the room while reliably keeping extensive sunlight and heat out.
Large glass surfaces can be easily shaded with external venetian blinds and roller shutters for optimum heat protection in summer. Window awnings blend elegantly into any home architecture and set tasteful textile design accents on the building’s facade.
If desired, insect screens can reliably keep mosquitoes, wasps and even pollen outside.
All these solutions can be easily combined and are available in a range of models, colours and designs. They are also particularly ideal in combination with our European tilt-and-turn windows as you can open your window inwards at any time without first having to remove the sun or insect protection.
Low-Emissivity Glass
Low-E glass is an energy-efficient way to control the heat entering and leaving a house. This glass works by reflecting heat to its source. It transmits visible light but blocks heat-producing ultraviolet light and requires less artificial heating or cooling to keep the room temperature comfortable.
Low-E glass and argon filling are standardly included in every window system of ECOWINDOWS' product range. This enhancement significantly improves the performance of our windows compared to other window types.
Install Solar Control Glazing
An excellent and ultimate solution to protect your home from overheating is the installation of solar control glazing to reflect incoming light.
ECOWINDOWS’ new generation of premium insulating glazing combines excellent thermal insulation and high solar energy gains with the best colour-neutral light transmission.
Our premium solar thermal glass makes your rooms brighter all year round. It also provides more solar heat gain in winter, maximum transparency, and excellent energy efficiency.
On the other side, our anti-sun glass offers even more sun protection in summer, especially for large glass surfaces. It also prevents excessive temperature increase in living spaces while allowing a lot of brightness and daylight into the rooms.
Go Passive House
The ultimate solution for stable internal temperatures is a Passive House. This type of building has exceptionally high standards for all its building components.
A Passive House creates a controlled internal environment with a combination of several components. It requires high insulation, an airtight building envelope, ventilation with heat recovery, a thermal bridge-free construction and high-performance double- or triple-glazed windows and energy-efficient doors that avoid any air gaps.
The goal is to create an ultra-low energy building that provides a high comfort level and healthy living environment while using very little heating and cooling energy.
This construction method helps generate stable internal temperatures of cosy 20-22°C all year round, day and night, while the outside temperature varies during winter and summer.
If you would like to learn more about our sun management systems, premium insulating glazing or Passive House windows, please do not hesitate to contact us today. We look forward to hearing from you!
Last month, the government announced changes to the Building Code to increase the energy efficiency of buildings. This update includes the increase in minimum R-values for residential and small buildings.
The new requirements will be introduced over the next two years and will vary according to six new climate zones.
Image source: Building Code Update 2021 – page 13
New Minimum R-values for Windows in Residential Buildings
Among other parts of a new building, windows will also have to increase their performance and hold more heat inside the house.
By the end of 2023, all parts of the country will have to achieve an R-value of at least R0.46 (climate zones 1-4). In addition, houses built in climate zone 5-6 will have to reach an R-value of at least R0.50.
Increasing the minimum insulation level for windows across the country is a much needed and necessary decision as windows represent the largest source of heat loss in a home.
However, the newly introduced performance requirements do not favour one type of window over another and allow multiple solutions to improve the insulation performance. Although not mandatory, the government expects building solutions like reflective glass with Low-E coating and thermally broken window frames to become more common options for meeting the requirements.

Comparison with the German Standard
As a world leader in manufacturing high-performance windows, Germany has a long history of stringent and rigorous government regulations, the so-called EnEV law. This law outlines the requirements for newly built and existing homes' energy efficiency to ensure high-quality insulation and low heat loss rates.
The German EnEV law regulates the required U-value rates for each housing area, including the windows. Hence, it is only allowed to install double-glazed windows with a low U-value of 1.30 in German houses. This value equals an R-value of R0.77 compared to New Zealand's R0.46 and R0.50 as a minimum requirement.
Still outperforming the Code
Increasing the insulation of New Zealand houses will help to improve current construction weaknesses. However, the announced changes could go much further.
All our products are manufactured in Germany and Europe. Thus their performance is oriented on the high standards and long history of energy-efficient building in these markets. Therefore, Low-E glass (low emissivity glass) and argon filling are already standardly included in every window system of ECOWINDOWS' product range. This enhancement significantly improves the performance of our windows compared to other window types.
Our heat protecting double-glazed window systems achieve R-values starting at R0.91, which already outperforms the required values of R0.46 and R0.50 of the new Building Code by far.
ECOWINDOWS standard triple-glazing offers values as low as R2. This performance can get even further enhanced depending on the selected window system.
High-Performance Building Solutions
We believe it is crucial to utilise windows that follow the highest standards and building requirements, such as those in Germany. This approach allows us to create dry, warm and healthy homes for everyone here in New Zealand.
Our high-quality and carefully manufactured German and European windows achieve the best energetic results for a home. Our products are made with decades of experience in energy-efficient building in Europe, where high-quality windows are commonly used for a long time.
No matter your requirements, ECOWINDOWS offers wholly customised solutions for new buildings and renovations alike. Contact us today to find out more about our service and product range.
The type of glazing plays a crucial role when building or upgrading your home. Whereas only single-glazed windows were used in the past, modern houses can now be built with double-, triple- and even quadruple-glazed windows.
If you decide to install new windows in your home, double-glazing is the minimum upgrade you should make. It offers a significant improvement in terms of insulating properties, comfort and wellbeing.
What is Double-Glazing?
Double glazing, also often referred to as thermal insulation glazing, is glass for windows made of two panes. These two panes are firmly connected at a certain distance.
A so-called spacer, typically made of stainless steel, aluminium or plastic, separates the window panes and maintains their distance in an airtight manner. This design ensures that no air can escape or moisture enter. The gap between the panes is effective for sound and heat insulation and acts as an insulating air cushion.
Even if the spacer is only a tiny part of a window, it is one of the most critical components. Its effectiveness is measured in its ability to create a warm edge, which refers to the interaction between the panes, the window frame and the spacer to ensure optimal insulation.
Heat Protecting Double-Glazing
Additional optimisation measures further improve the thermal insulation of classic double-glazing:
Low-E glass (low emissivity glass) ensures a further reduction in heat losses through the window. Thanks to the heat protection layer applied, the pane reflects heat into the room.
Furthermore, the air filling between the two panes has been replaced with noble gas, such as argon or krypton. As the heat conduction of these gases is lower than that of air, the thermal insulation effect of the double-glazing is further improved.
Both, Low-E glass and argon filling are standardly included in every window system of ECOWINDOWS’ product range.
Performance Values
The most important criterion to measure the energy efficiency of windows is the heat transfer coefficient, the so-called U-value. The U-value measures the heat permeability of building elements and indicates the heat flow through the window.
In contrast to the desired high R-value, a lower U-value indicates better performance and insulation. The R-value is the reciprocal of the U value and vice versa (R = 1/U and U = 1/R).
In most countries, U-value is expressed in the modern form of the metric system, in SI units, as watts per square metre-kelvin: W/m²K. The rule here is that the lower the U-value, the better the thermal insulation.
As depicted in the graphic below, there is a clear difference in performance values between single-, double- and triple-glazing.
With triple-glazing, a second Low-E coating is applied on the outer glass pane to reflect heat from the outside, which prevents overheating of the house, especially in the summertime.
ECOWINDOWS standard triple-glazing offers values as low as Ug 0.5. This performance can get further enhanced depending on the selected window system.
The Benefits of Double-Glazed Windows
Compared to single-glazed windows, double-glazing saves a lot of energy that would otherwise be lost. So investing in high-quality glazing does not only save a lot of energy and heating costs but also increases the comfort of your home and your overall wellbeing.
Double-glazing outperforms conventional and outdated single-glazing in many areas, particularly offering:
With single-glazing, much of the heat in a room escapes through the windows. However, a particularly low thermal conductivity characterises double-glazing on the other side.
Especially windows that are enhanced with Low-E coating and noble gas filling offer the best performance values. Therefore, these two enhancements are standardly included in all our products. As a result, these high-performance windows effectively ensure maximum thermal insulation for your home.
The choice of glazing can positively influence the level of noise entering your home.
Modern double-glazed windows effectively reduce noise transmission through the glass into the house, ensuring efficient soundproofing and a comfortable and quiet living atmosphere.
Our windows standardly provide a noise reduction of 32dB and can be enhanced up to 60dB for particularly noisy environments, such as residences located nearby the airport.
Laminated safety glass plays an essential role in protecting you and your home. It is made of two panes with a unique film in between. If a pane is destroyed, the splinters adhere to the film, a beneficial feature to prevent injuries.
Even the lowest class of anti-impact protection effectively prevents the pane from being smashed open so that it might collapse and give entry to an intruder. There are even higher upgrades for glazing available that will offer maximum security for your home.
Furthermore, the frames of burglar-proof windows are anchored several times in different places in the building wall. In addition, their interior fittings contain mushroom cams which offer high resistance against being pried open.
Outdated and cold single-glazed windows are a magnet for water evaporation in the air, leading to condensation and puddles on the window sills. This moisture in the home can cause severe health problems for the residents.
The glazed surface of a double-glazed window effectively eliminates the formation of condensation on the inside of the window panes, creating a warm, dry and healthy home.
European and German tilt and turn windows with double-glazing are not only exceptionally robust and resilient, but they also offer a high level of user-friendliness.
The panes of tilt and turn windows are very easy to clean. You only have to open the window inwards to wipe the outside surfaces. The inside of the windows does not require any additional maintenance.
Double-glazing and triple-glazing are recognised as one of the best improvements you can make to your home because it saves a lot of energy and heating costs. So, it is no surprise that there is an increased demand for houses with double-glazing as this type of glazing adds significantly to the comfort of a property.
ECOWINDOWS offers a variety of European and German double-, triple-, and even quadruple-glazed window systems. We deliver our products safely to any destination in New Zealand nationwide and no matter how remote.
Contact us today if you'd like to learn more about our product range and how double-glazing can benefit your home.

Thomas, Bjorn & the ECOWINDOWS Team
Over many decades, Germany has gained a reputation as a pioneer in energy-efficient building, especially when it comes to manufactured high-performance windows.
Several well-known German window manufacturers with a long family history are at the forefront of world trade. The international demand for their products is continuously high, and rightfully so: windows from Germany offer an exceptionally high quality of craft, production techniques and durability.
Made in Germany: highest expertise and quality
The slogan “Made in Germany” is widely acknowledged as proof of above-average quality and innovative products.
Germany’s window manufacturers are maintaining and increasing their building standards by constantly improving their production techniques and the technical details of their window profiles. The careful selection of high-quality materials is an elementary component of the entire production process.
Therefore, it is not surprising that window manufacturers from Germany are among the best in the world. PVC, timber, wood-aluminium and aluminium windows "Made in Germany" are internationally in great demand.
Pioneering window technology
At the beginning of the 20th-century, tilt and turn windows were invented in Germany. Today they are the standard window type used in Germany and most of Western Europe.
Tilt and turn windows have several benefits compared to other window options, including safe ventilation, easy maintenance, high safety features and quality insulation. They can also be opened flexibly in two ways: fully inwards and tilted from the bottom.
The German window system proved itself so efficient that it was quickly adopted by other European countries, demonstrating its outstanding performance.
Nowadays, tilt and turn windows are manufactured in many countries, often offering the same quality as German windows, like those from Austria and Poland.
Germany’s strict building regulations
Germany has a long history of stringent and rigorous government regulations concerning the energy efficiency of newly built and existing homes. The standards are outlined in the so-called EnEV law and focus on high-quality insulation and low heat loss rates. This way, houses are warm and cosy while keeping the power bills to a minimum.
Germany’s strict regulations ensure that German window manufacturers develop innovative and energy-efficient solutions only. As a result, they build exceptionally high performing windows with triple and even quadruple glazing, which are exclusively available at ECOWINDOWS in New Zealand.
Certified excellence
One organisation responsible for regularly monitoring manufacturers is the renowned and internationally accredited Institute for Window Technology (IFT) Rosenheim, which is based in Germany and specialises in assessing the performance of European windows and doors.
All ECOWINDOWS products are rigorously tested and certified by the IFT Rosenheim. The windows and doors must pass a series of detailed and strict tests to prove their exceptional air permeability, watertightness, and resistance to wind load.
The tests are implemented according to the highest European standards (EN and ISO) and ensure the best quality, efficiency, and safety of our double- and triple-glazed windows and entry doors. The results are then assessed for compliance with the New Zealand Building Code.
This rigorous testing procedure allows ECOWINDOWS to offer our New Zealand customers windows and doors with the highest quality and durability.
Renowned German window manufacturers
ECOWINDOWS offers windows from a range of renowned and certified German manufacturers exclusively produced in Germany. These products match the German market's strict requirements and high standards, which helps to create dry, warm, and healthy homes here in New Zealand.
These traditional family-owned window manufacturers have a long history and great expertise in crafting outstanding products of supreme quality.
German building solutions offer excellent energetic properties and proven durability. Both the longevity and the reduced energy costs speak clearly for the use of quality windows.

Durable colours for your home.
Coloured PVC windows give your house a unique character and style. By matching the colours of the facade or the environment, coloured windows can shape the appearance of every house. This way, every building becomes an attractive and individual eye-catcher.
Long-lasting, colourful windows with acrylcolor.
Coloured acrylcolor windows do not only set accents in the facade design of your house. They also require very little maintenance and are extremely easy to care for. The silk-matt, smooth and pore-free surface is also insensitive to the build-up of dust and dirt. As a result, peeling, chipping, and repainting is no longer required.
What is acrylcolor?
Acrylcolor is created in a so-called co-extrusion colouring process. This process enhances and protects PVC window systems in a long-lasting fashion. The white PVC base body and the coloured acrylic glass are permanently connected. The fusion of the two materials creates a satin-matt outer acrylcolor surface that can withstand any weather condition for decades to come.
A premium colouring process.
The advantages of acrylcolor.
Acrylic glass is an extraordinarily colour-stable and durable material. It shows no colour change - even after years of intense weather exposure.
For decades acrylic glass has proven its resistance to the effects of wild and rough weather. Windows featuring acrylcolor profiles are incredibly robust, even under intense climate conditions.
Windows made of acrylcolor profiles require very little maintenance and are extremely easy to care for. They are dirt-repellent and can be cleaned with simple detergents. No peeling, chipping, or repainting, and thus, no unnecessary maintenance costs.
Acrylcolor profiles have a semi-gloss, smooth and non-porous surface. The fusion of PVC and acrylic under great heat makes the windows exceptionally sturdy and robust. Not only do they have a high level of scratch resistance, but they are also resilient to the build-up of dust and dirt. However, should a scratch become visible on the profile, it can be easily removed using an ordinary cleaning pad.
In acrylcolor elements, the sun's rays are reflected by the white body beneath the infrared-permeable paint layer. These reflective properties minimise overheating of the profiles and thus the risk of deformation.
Like all plastic elements, acrylcolor windows can be easily recycled. If the windows are disposed of after a long period of use, they can be transformed into high-quality raw materials for new windows.
Wide range of designs and colours.
ECOWINDOWS offers a wide range of colour options from a comprehensive acrylcolor portfolio for GEALAN’s S9000 profile system - a state-of-the-art system for windows, doors, and slider doors, which are also suitable for Passive House building.
The colour range includes eight shades, from deep black and various tones of grey to sepia brown. We also offer three metallic shades, which are unique in the market. This colour selection enables harmonious combinations with aluminium elements.
