Thermal insulation and heating cost savings

Good thermal insulation reduces heating costs in winter and acts as a heat shield in summer.
Our windows feature modern thermal insulation glazing with high insulation values for the window frames.

 

Well insulated all year round

Optimal thermal insulation helps you reduce your energy costs throughout the year.

High-performance glazing and high-quality frames are important for good thermal insulation and the comfort of your home. Even our basic window glazing features thermal insulation and thermally optimised glass spacer Depending on the glazing structure, the spacer joins two or three single panes into one insulation glass unit. Its function is to seal the cavity between the panes towards the outside. Heat-optimised spacers improve the thermal insulation properties of the window.s.
 

Energy savings in winter: reduce your heating costs!

In winter too cold, in summer too hot: this type of room climate will not only adversely affect your well-being, but also your energy costs. The heating energy consumed with old windows with single or double glazing is three times higher than that with new Finstral windows.
 
 
 

A worthwhile investment!

Save money and resources with Finstral windows: our innovative window and door systems will help you renovate your home in contemporary style.

investing in new thermally insulated windows quickly pays off. At current energy prices, you could save several hundred euros a year on a detached house. You will also enjoy an improved level of living comfort: thermally insulated windows radiate less cold and are more airtight.

 The graphic on the right shows the expected energy costs without renovation (black) and renovated with Finstral windows (white).
 
 
 

Energy savings in summer: give your air-conditioning system a break!

Our standard thermal protection glazing offers excellent protection from the summer heat as well as outstanding thermal insulation in winter.

Your rooms remain pleasantly cool, you only need solar protection later on in the day and air-conditioning costs are significantly reduced.
 
 
 

The right window for the climate

We offer special glazing in our range that is ideally suited to varying regional climate conditions.

Our Super-Valor and Energy-Valor glazing have been specially developed for cold regions: in addition to good insulation against heat loss, they allow plenty of light and solar energy into your home.

In Mediterranean regions our Plus-Valor Mediterran and Sun-Block glazing provide effective protection against excessive sun.
 
 
 

Triple glazing: singularly better

Double thermal protection glazing, with a single-sided coating and argon The cavity between the glazing panes is filled with argon, a noble gas, in order to improve the thermal insulation properties of windows and doors. Argon gas has a greater insulating effect as it does not conduct warmth as well as air. filling, is nowadays the standard for modern window construction.

To further improve your thermal insulation, we recommend our triple glazing. The double coating of the glass and the two cavities between the glazing significantly increase its effectiveness.

UW This is the heat transmittance coefficient of the window element. The value indicates the amount of heat transferred in one hour through one square metre of a component at a temperature difference of one Kelvin (equivalent to 1°C). The lower the heat transmittance coefficient, the less warmth that is lost through the window and the better its heat insulation properties. The unit is [W/m²K]. up to 0.75 W/m²K
