Internorm passive house windows, a pinnacle of efficiency and sustainable comfort.
All of our windows and doors were designed with our customers in mind, which means cleaning them is really easy. Internorm’s developers have hidden as many parts as possible in the window frame and sash.
Thanks to AT-ECO you hardly notice a window exchange. Our installation team measure your windows and check structural conditions. Together with you, we are developing an exact time schedule.
Internorm products stand for excellent quality! We provide technical advice and service when supplying our products and take installation very seriously.
With Internorm you do not need to decide for either uPVC/Aluminium windows or Timber/Aluminium windows. Both windows can be combined without any problems. The aluminium clad on the outside looks exactly the same. Thus, you can decide which material you would prefer for which room.
Our sun protection additions are made to block out sunlight with every window for your loving home. We can provide over nine varieties of shutters and blinds plus an option to include control technology that enables you to automatically close your shutters/blinds at a push of a button.
