Insulation and energy

How well do new windows insulate against cold and heat?

New windows with high-efficiency glass provide strong thermal insulation. They limit heat loss in the winter and keep the heat out in the summer. This increases living comfort, reduces energy consumption and can contribute to a better EPC score for your home.

Do new windows also keep the heat out in the summer?

Yes. High-efficiency glass not only helps to keep heat in during the winter, but also limits heat penetration in the summer. This ensures a more pleasant indoor climate, especially during warm periods.

What is high-performance glass (HR++ glass)?

HR++ stands for high-performance double glazing, consisting of two panes of glass with an insulating cavity in between. This cavity is filled with a noble gas, such as argon, which significantly improves the insulation value of the glass.

What is better: double glazing or triple glazing?

Double glazing is the standard today and is suitable for most homes. Triple glazing offers extra insulation and soundproofing and is especially interesting for new construction or very energy-efficient renovations.

Does triple glazing make sense for your home?

Triple glazing insulates better than double glazing thanks to three panes of glass and two insulating cavities. It is especially interesting for well-insulated homes, such as new builds or thorough renovations.

For older homes, double glazing often already offers a major improvement and is usually sufficient. Triple glazing is heavier and more expensive, so the window profile and fittings must be adapted to this, especially with large window surfaces or sliding windows. Premiums can partially offset the price difference. Good ventilation remains important to avoid condensation and moisture problems, just as with double glazing.

Are soundproof windows really noticeable?

Yes. Thanks to modified glass compositions and well-sealing profiles, soundproof windows significantly reduce disturbing noise from outside.

Are soundproof windows a good idea for a busy street?

Yes. For homes along a busy road or in an urban environment, soundproof windows can noticeably reduce outside noise. This increases peace and comfort indoors.

Do new windows affect my EPC score?

Yes. Well-insulating windows contribute to better energy performance of the home and can positively influence the EPC result.

Can old windows be renovated or is it better to replace them?

In some cases, renovation is possible, but replacement usually provides better insulation, comfort and energy savings. InstaWindow always assesses this fairly per home.

Do new windows help against drafts?

Yes. New windows seal better than older models and significantly reduce drafts. Thanks to modern profiles and correct installation, your home feels more comfortable, without cold air currents along windows.
