uPVC & GRP Composite Doors

Composite Doors take their name from the composite materials that make up the inside of the door. There are slight variations available, but most high quality composite doors comprise of a timber hardwood sub-frame that houses the composite material. The doors are typically hung in a uPVC steel re-inforced frame.

The composite material inside is usually high-density foam such as polyurethane, which once inserted forms a hard solid core. This is far superior than the almost weightless Styrofoam that makes up a re-inforced uPVC panel. It is the high-density core of a composite door that gives the door its notable strength. Anyone who has tried to carry a composite door will testify to this; weighing approximately 75Kgs and over, it is easy to see why these doors are generally considered impossible to break into! The standard thickness for a Composite door slab is 44mm, almost twice the thickness of a uPVC panel, which are 24mm or 28mm as standard. Many customer have indicated that after replacing an old uPVC or timber front door with a Composite there were significant reductions in heat loss and external noise was greatly reduced. The highly durable faces of our Composite Doors are a 3mm thick skin made up of either GRP, glass re-inforced plastic, UPVC or aluminium. We tend to use GRP as standard as Composite Doors with an aluminium face are waning in popularity and availability, as they are notoriously bad conductors. Composites with UPVC skins are also less popular as the skin is susceptible to the same downfalls as UPVC doors; warping under extreme weather conditions and also colour fade in direct sunlight.

The majority of Composite doors now use a coloured GRP skin on the external face of the door, keeping the internal face white to make the door more in keeping with general internal decor. GRP skins are available in a variety of colours, and importantly GRP is not known to fade or discolour in direct sunlight as UPVC does. GRP skins traditionally have timber grain effect, giving the appearance of real coloured wood. This proves to be a big selling point for Composite doors, as they are a lot more resistant to weathering and age than wooden doors.
