Roller shutter box : FoKus®

Internal roller shutter

The FoKus® internal roller shutter range combines all the requirements for tomorrow’s buildings by reducing its overall impact on human health (solar gain management, perfect airtightness, maximum acoustic comfort) and on the environment (high thermal insulation and recycling of the product at the end of its life).

In this way, it meets the new energy standards: thermal, acoustic and aeraulic. These values are certified by the CSTB and FCBA.

FoKus® has won the bronze disc at the Inovyn Awards at the 2019 edition of the K trade fair in Düsseldorf.
