What goes into your door.

Materials, insulation and the complete doorset.

Get to know the parts behind the finish. This guide explains the construction described by the existing shop and the details to confirm for your door.

Beyond the surface.

The existing shop describes GRP outer skins, a polyurethane insulating core and internal reinforcement. The exact construction depends on the chosen doorset; its supplier specification must be confirmed before ordering.

The details that matter.

Your final specification should identify the supplier, door thickness, core, frame and glazing. Thermal performance and security claims need to match that exact combination.

Fire doors follow a separate specification.

A standard composite door is not a fire door. Fire doors must be specified and installed as a complete approved doorset. HHI must confirm the applicable fire, smoke, hardware and installation requirements for the property.
