ECLAZ® Glazing by Internorm: Maximum Insulation with Natural Light

Developed by Internorm, a leading European window and door manufacturer, ECLAZ® glazing is a type of low-emissivity, or low e, glass panels designed to improve thermal insulation for windows and doors. It incorporates a special coating that reflects heat into the room, reducing heat loss through the window.

With rising energy costs and concerns about climate change, ECLAZ® glazing offers an effective solution to reduce a home’s energy consumption without sacrificing natural light. By redirecting natural heat back into a building, occupants can enjoy a more comfortable environment without artificial light that hurts the eyes or heating that dries out the air.

Discover the Advantages of ECLAZ® Glazing

If you’re considering upgrading your windows, you might be overwhelmed by the sheer number of options available. However, ECLAZ® glazing stands out as an innovative and highly effective solution that can offer home and building owners a wide range of benefits. Not only does it provide exceptional insulation, but it also allows natural light to enter through the window. This creates a brighter and more inviting space to encourage a healthier lifestyle while improving sustainability. So, here’s how ECLAZ® glazing can improve your home and your life.

Lowering heating expenses:

Choosing ECLAZ® glazing for your windows directly helps you lower your heating expenses. These windows offer top-of-the-line thermal performance, matching the insulating properties of any other triple glazing. But, ECLAZ® glazing also reflects heat back into the room helping your home retain even more heat and reduce your reliance on artificial heating systems.

To reflect heat back into the room, ECLAZ® glazing uses multiple layers of metallic oxides applied to the glass surface using a vacuum deposition process. These layers reflect long-wave infrared radiation, the type of heat energy emitted by objects at room temperature. When this radiation hits the coating, it reflects back into the room, rather than passing through the glass and being lost to the outside environment. This reflective effect helps keep a room at a more stable temperature by reducing heat loss through the windows.

Essentially, ECLAZ® glazing uses innovative techniques to reduce heat loss through windows so you can lower your heating expenses. This makes it a great investment for any homeowner looking to improve their home’s energy efficiency.

More daylight = better health & well-being:

Natural daylight brings significant benefits to human health and well-being. Exposure to natural light can regulate the body’s internal clock, leading to better sleep patterns and overall mood. Additionally, natural light is an excellent source of vitamin D, which is essential for strong bones and healthy immune function.

Apart from its physical health benefits, natural light has been shown to enhance cognitive function, productivity, and alertness while reducing symptoms of depression and anxiety.

With these significant health and well-being benefits, allowing natural daylight into your home needs to be a top priority. ECLAZ® glazing can help let more natural light into a room without sacrificing thermal performance. It still uses a triple-pane system so you get the same insulating properties of an insulated glass unit. But, ECLAZ® glazing uses a specialized coating to allow more natural light through the window. In fact, it allows up to 10% more daylight in a home’s interior compared to standard heat-insulating glass. This also helps you harness the power of solar heat as more sunlight can enter your home.

Switching your windows to ECLAZ® glazing glass panes by Internorm can help you improve your health and well-being without sacrificing the efficiency of your home.

More Light And Transparency:

Simply put, ECLAZ® glazing lets more light into your home while giving you a more transparent view through your windows. With a light transmission factor of 77%, windows with ECLAZ® glazing can help open up any room. This high level of transparency provides you with a clear and beautiful view of the outside world. Whether you live in a bustling city or in the midst of nature, ECLAZ® glazing can help you make the most of your surroundings by providing a brighter and more open living space.

The transparency of ECLAZ® glazing glass panes also provides a sense of openness and spaciousness to your living space. With the ability to see through the glass, your living areas feel more expansive and less confined. This can be particularly beneficial in smaller homes, where natural light and transparency can help to create the illusion of a larger space. Additionally, the high level of transparency allows you to connect with nature and the outdoors, even when you’re inside your home. This connection to the outside world can improve your mood and overall well-being.

By providing a significant amount of natural light into your living space, ECLAZ® glazing can help you to feel more energized during the day and more relaxed at night. So, let ECLAZ® glazing create a more natural and comfortable environment for you and your family.


Any environmentally conscious homeowner can appreciate the sustainability benefits that ECLAZ® glazing offers.

First and foremost, the glazing provides exceptional thermal performance, improving the energy efficiency of your home’s heating system. This can lead to significant energy savings, reducing your carbon footprint and overall energy consumption.

Another way ECLAZ® glazing improves the sustainability of your home is through its durability and longevity. The triple-pane system is designed to be highly robust and long-lasting, meaning that it will require less maintenance with a longer lifespan. This directly reduces the amount of waste that your home produces.

Internorm also uses eco-friendly production processes that minimize waste and pollution when creating windows with ECLAZ® glazing. These practices make ECLAZ® glazing a more sustainable choice for your home and the environment.

Finally, ECLAZ® glazing can also help to improve the overall indoor air quality of your home. The glazing is designed to provide exceptional insulation, which reduces the need for mechanical ventilation systems that can contribute to poor indoor air quality. The natural light let in by ECLAZ® glazing glass panes can also help fight mold and mildew growth further improving the air quality of your home.

Upgrade Your Home with ECLAZ® for Triple-Glazing & ECLAZ® ONE for Double Glazing

Upgrade your home with ECLAZ® for triple-glazing and ECLAZ® ONE for double-glazing, and you’ll enjoy a host of benefits. The glazing is designed to provide exceptional thermal performance, reducing your energy consumption and carbon footprint. It also allows natural light to flood into your home, creating a brighter, more inviting living space that can improve your mood and overall well-being.

On top of this, ECLAZ® glazing offers the durability you need making it a long-lasting window solution that minimizes your home maintenance needs.

Every homeowner that wants to improve their home’s energy efficiency, indoor air quality, and sustainability can use ECLAZ® glazing to help meet their goals.

Our Most Frequently Asked Questions

Properly informing and educating our clients on our products is one of our most important values. We strive to answer all your questions, as we understand that purchasing your home’s windows and doors is an important decision.

1. What are the advantages of tilt & turn windows?

VENTILATION is one of the most obvious benefits of tilt and turn windows, since the dual option allows for a more precise control of the homeowner’s environment. This feature allows one to for example, be able to open the window during a summer rain storm using the tilt feature, while preventing water from entering the building. As hot air rises, the tilt option allows for better ventilation and is efficient in getting rid of stale air. It also allows for the entire window to be completely open using the turn option and is therefore a product with a varied yet accurate control of ventilation.

EASY TO CLEAN is something we seldom hear one say when North American windows are involved. However European tilt & turn windows allow you to safely clean the exterior of your windows whilst inside your home, by placing the window in the turn position. Say goodbye to ladders and back strains, as your exhausting spring cleaning just became a regular easy maintenance.

MORE SECURITY is an automatic bonus when purchasing tilt & turn windows, as there are up to 7-point locking systems and is impossible to be forced or pulled open from the exterior. The tilt position is also a fantastic feature that aids in enabling ventilation while keeping the high security aspects of the window.

AESTHETICS is all the rage when purchasing your windows; and with reason. So why not combine high quality with style? Whether you opt for UPVC or wood-aluminum windows, your options are nearly limitless with the combinations of handles, colors, glazing, and frame choices. Our windows offer multiple sizing options, where a maximum size of 51 in. wide by 106 in. high for one operating panel can be achieved with our KF 520 model. This can be compared to the North American window average of only 31 in. wide by 72 in. high.  A beautiful home means well-planned details and choosing the perfect finish and size can really complete a look and increase the value of your home.

HIGH-PERFORMANCE ENERGY EFFICIENCY is what makes tilt & turn windows stand out massively from traditional North American windows. Our windows are Passive House certified, which means that they are able to maintain an optimal indoor climate, without increasing electric costs or causing harm to the environment. European windows have been tested for higher standards in energy conservation and long-lasting product quality. This makes for tilt & turn windows to be the most eco-friendly and economical option.

2. What are the advantages of a lift & slide door?

Lift & slide doors allows for the same advantages as tilt & turn windows. 

They are also highly praised for their

LARGER GLASS PANELS AND A BETTER VIEW in which we are proud to be able to reach and offer a size of up to 17 ft. wide by 9 ft. high in two panels. This allows homeowners to create a brighter space and take full advantage of beautiful sceneries.  

BETTER SOUNDPROOFING removes any limitations or annoyance associated with noisy neighbors, or even living next to a busy highway. Suddenly noise levels become extremely manageable and quality of life at home improves.

ADVANCED HARDWARE means that our very heavy and robust lift & slide doors actually require little effort to lift the sliding panels, followed by smoothly moving them open and closed.

ADDED SECURITY is attained with an extremely heavy and robust product. Just like the tilt & turn windows, multi-point locking systems that surpass industry standards make it impossible to break in. 

3. How much more performant is a 48mm-56mm triple pane glass vs. a regular 26mm low-e argon glass?

The more number of glass panes used, better the insulating property. The thickness of each individual pane is an additional factor to consider. European windows in particular are better resistant to condensation which reduces the energy consumption especially in colder climates, such as those in North America. 

While most North American windows use double and thinner panes, European windows have triple and thicker panes, with integrated blinds as a cherry on top.

Recently, North American windows begun introducing triple panes. However, even with this new development, the outer and inner panes have smaller space between them than European panes, and the glass itself is thinner. This means that North American triple pane windows are still not considered as resilient as European windows are to extreme climates, like the ones we have in Canada. 

The chemical makeup in European windows, such as UPVC, Low-E glass and a low U-value improve the thermal efficiency of the windows, ultimately keeping the heat out in summer and prevents the indoor heat from escaping during winter. These combined with the proper number of panes as well as sufficient pane thickness, is the recipe for a perfect window. To compare, North American double pane Low-E argon glass has a U-value of 1.5 – 1.6, whereas a European triple pane window can have a U-value as low as 0.4, proving once again its above industry standards.

4. Are premium window and door systems worth the extra expense?

Although the initial purchase of European windows and doors is slightly more expensive, their overall value including their astounding average lifespan of 60-70 years and energy savings that take affect the moment they are installed, significantly outweighs the initial slightly less-expensive costs of the North American windows and doors.

There is an unfortunate current trend in the North-American market in which homeowners allow their contractor to make most of their building materials purchasing decisions. These decisions very frequently based on cost, and therefore disregard performance, quality and lifespan of the windows and doors. This can ultimately hinder the homeowner’s quality of life and energy expenses.

On average, by spending around 10-15% more on these high-performance products, you are in turn saving a lot more in the long run, allowing for this important purchase to be one of the greatest investments in one’s life.
