Interoc Fasad’s operations started already in the 1960s. Until the 90s, Interoc Fasad was operated under the Opus brand. Within the company, from masons to company management, there is a genuine craft tradition. Over the years, we have renovated many old cultural properties where there are special requirements for knowledge of older materials and methods, but also how older facades and property details should be handled in order to be restored.

Interoc Dörr & Fönster was started in 2012 and is today the leader in Sweden in window replacement.
We are supplier independent and cooperate with all major and many smaller window manufacturers. With this, we can satisfy all requirements for form and function.

We can also verify how much your windows save in energy consumption, how much noise they dampen and how much they improve the air environment for the residents. Our long-term and sustainable way of thinking and building permeates everything we do.
