The products are green-tinted, extruded polystyrene (XPS), rigid board thermal insulation.
The different model designations are based on the ends being squared or shiplapped, or the insulation having a thin plastic cap sheet on both sides. The insulation is available in various thicknesses, ranging from 12.5 mm to 102 mm, in widths of 600 mm or 1 200 mm, and lengths of 2 428 mm or 2 743 mm.
