As each Internorm entrance door is custom-made in Austria, you can customise it to your taste, whether you choose a full door leaf or a door with glass cut-out and then select the desired side elements, fanlights, handles, colours etc. the choices are only limited by your imagination.
Internorm entrance doors are available in both aluminium and timber/aluminium offering the perfect burglary protection in attractive design. Standard 5-point locking from renowned manufacturer KFV renders these entrance doors burglary-proof. Countless door models are available. Colours, handles and glazing options can be designed exactly according to your ideas. The inside of the door features a multi-layer plate setup which ensures best thermal insulation and high sound protection, reducing sound by as much as 36 decibels.
Of course, internorm entrance doors can also be equipped with finger scanner, keypad (code keyboard) or further security systems.
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.
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.
