The Capstone 44m Door

Manufactured using grained and smooth 2mm thick impact resistant GRP SMC skins and are available in a wide variety of styles and colours including wood stains. Stiles and Rails are manufactured from a water-resistant pure PVC polymer and reinforced using LVL (Laminated Veneered Lumber) timbers with a minimum density of 570 kg/m3.

The SMC skins and sub frame door assembly are fully bonded using a Urethane Adhesive Resin. The door is filled with CFC-Free Polyurethane foam, a superb insulation material which vastly reduces the transfer of heat through the door. With a density 44.5 - 45.5 kg/m3 this provides insulation that as part of a doorset assembly achieve a U value as low as 0.8W/m2k
