The insulated composite door is strong, durable and secure. Manufactured to an exacting and high quality specification. It’s strength comes from the construction of it’s sub-frame in solid, water-resistant polymer material, reinforced behind with Laminated Veneered Lumber (LVL) The thermoset GRP skins are then bonded to the sub frame, and its core filled with high density, 100% CFC-free polyurethane foam.

The thermoset GRP skins are depression moulded featuring a lifelike grain effect and high definition panels providing an
authentic timber like door with all the advantages but limited maintenance. Thermoset GRP cannot expand or contract laterally such that the door cannot increase or decrease in size, an advantage over other commonly used materials.

The factory finish colours of White, Black, Blue, Green and Red have pre-pigmented GRP skins which are over-sprayed with a UV stable paint.
