Insulated Roof Panel PIR 80mm

The Briarwood Insulated Roof Panel is designed for use on inclined/apex/pitched roofs or as cladding on walls, whether they are positioned horizontally or vetically. It is ideal for exterior insulated cladding across various buildings, including industrial, commercial, and public facilities (as well as being used on agricultural structures). With a sturdy PIR insulated core flanked by metal sheets on both sides, this Insulated Roof Panel offers excellent thermal insulation while enabling significant span widths. It requires a minimum installation angle of 4 degrees, accounting for any potential sagging.
