What is a composite door ?
The idea of the composite door is simply to be more aesthetically pleasing than a uPVC Panel door by replicating the natural appearance of a traditional wooden door. Combining this look with modern materials provides the advantages of low maintenance and durability.
Doors consist of an outer frame and an opening leaf. The door leaf is the composite part, sometimes referred to as the door slab which is made up of a outer layer door skins and a central core.


Outer Frames

All composite doors are hung in uPVC outer frames, exactly the same as uPVC Panel or uPVC Glazed doors. These can be in standard gloss white or woodgrain foil finishes in a variety of colours. Quality of uPVC profiles vary between extruders and reinforcement specification varies between fabricators.


Core Construction Types


Foam filled
- A centre core of high density polyurethane foam which although is very thermally efficient will dissipate over time.

Monocoque
- A monocoque core construction provides strong reinforcement to the fibreglass door skin.

Solid Timber Core
- A solid timber core provides the strongest core construction. Constructed using Laminated Veneered Lumber (LVL)


Door Skin Construction Types


GRP - Glass Reinforced Plastic (also known as fibreglass) is moulded to create the replica wooden grained outer skins of the door slab. Finished by spray painting this option offers an endless palette of colours, although difficult to match exactly to a supposedly same colour outer frame. The paint finished door skins can be prone to scratching, although can be easily repaired with a little pot of touch-up paint.

Thermo Acrylic – Made from incredibly durable Acrylonitrile Butadiene Styrene these door skins are “colour through”. No scratching and can provide an exact match to a same colour outer frame. Available in both replica wooden grained and smooth finishes.

Aluminium – Metalic smooth finish which is powder coated with high specification marine grade paints. The strongest door skin although easily marked.
