The doors in a passive house plays a prominent role in two ways – firstly, the heat loss despite large glass surfaces can be reduced and secondly, windows increase the possibility for heat gain through solar energy. Internorm‘s highly thermally insulated windows do this exceptionally well: thermal insulation glazing as used in passive houses achieves Ug values of up to 0.4 W/m2K.
- Essential principles for the construction of passive house windows:
- Highly thermally insulated glazing
- Highly thermally insulated frame
- Thermally optimised edge seal
Passive House or PassivHaus
A benefit to installing Internorm windows and doors is that you able to achieve Passive House status which means your house has consistent, comfortable temperatures throughout the year, without using conventional heating or air conditioning systems. Using the existing temperature provided via solar radiation through the doors as well as the heat from appliances and inhabitants is sufficient.
The required heating energy for a passive house is only 10% of that needed for a conventional house. These extraordinary savings are rooted in the two basic principles of minimising thermal loss and optimising thermal gain.
Internorm also benefits from the following key features:
- Thermally broken Doors
- Noise Reduction
- In-frame ventilation systems providing you with a climate controlled system whatever the weather.
