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.
The simple addition of greater space and improved lighting can turn any room into a graceful centre point for the entire family to relax. Plus, it helps break down the barriers between the inside and outside to truly appreciate your gorgeous surroundings.
