Internorm are Europe's industry leaders and their windows are engineered to be outstanding at every level. The quality and feel of Internorm can provide the finishing touch to your home, Internorm are constantly innovating, with new, cutting edge features like the Itec concealed locking system and Smart home intergration. Internorm windows are specified beyond ordinary windows with features like all-round gaskets to prevent water and sound penetration, concealed hardware, symmetrical join lines and black gaskets between the panels to make the finished look clean and tidy.

The engineering that goes into Internorm windows is something special. Every single window is custom-built to order in Austria. Their designers go beyond the norm, and the manufacturing process has an obsessive number of checks, both electronic and human, to ensure that the finished product is perfect.

Internorm now uses iplus Low Carbon Insulating Glass as standard.

iplus glass is made with an original process to utilise renewable electricity rather than the traditional way with fossil fuels. This incudes solar and wind power at the manufacturing plant and helps reduce the carbon footprint of the glass by about 50% The glass also includes up to 20% recycled glass.

iplus glass contributes to making Internorm windows even more sustainable.
