All Rustique profiles are manufactured from acrylic high impact modified, Polyvinyl Chloride unplasticised compound (PVC-U).
Five fully enclosed chambers within the 70mm front to back profile have an increased wall thickness to offer additional product strength, rigidity and performance in addition to improved thermal efficiency.
The additional chamber enables galvanised steel reinforcement to be used for greater strength and rigidity.
Hardware and striker keeps are screwed into top hat fixing points and screw ports for an improved technical and enhanced security performance. The system has been tested to PAS024 security standard.
