Composite Doors

We use the DOORCO slab to make our composite doors. This slab offers a high level of security, with increased resistance to forced entry. Reinforced GRP skins and modern materials mean that unlike timber doors, this door requires very little maintenance. All the homeowner will need to do is occasionally wipe the door with a damp cloth to keep the good-as-new look. Within this composite door, we offer the ODL Europe TriSYS 3-part glazing cassette and Kubu smart hardware.
