New Barrisol® membrane Alphaperf

Barrisol® enhanced on its Perforés® range, the 10mm Alphaperf fabric (stretched membrane with 10mm perforations and an opening rate of 80%) is used as a ceiling for smoke extraction.

The air extraction devices are then placed above the perforated stretched membrane - Barrisol®’s Perforés® range makes it possible to meet standards of smoke extraction.
