Description

Absorber Linear Polar is a PET (100% polyester) lamella absorber for ceilings with concrete core activation, with vertical absorber elements bonded into aluminium carrier profiles, either butt-jointed in continuous runs or with joints. The profiles are fixed in rows to the soffit, and as the elements cover only part of the ceiling area, they have little effect on the cooling performance of the slab; length, height and row spacing can be chosen to suit. Typical applications are offices and meeting rooms, educational buildings, and exhibition and assembly venues.
