Composite Doors

Historically, the choice of entrance door has been limited to timber, which can expand, contract or warp and requires regular maintenance or PVCu which lacks the authentic wooden door look and can expand and warp but GRP faced composite doors offer the perfect alternative!

GRP Faced Composite Doors

The first impression a visitor gets of a home is the front door!

Why choose GRP Faced Composite Doors?

The skins on our door are manufactured from GRP (Glass Reinforced Polyester). They are compression moulded to give a high definition panel design which offers authentic timber appearance and the thermosetting manufacturing process means that they are unaffected by variations in temperature.

The stiles and rails are of a water resistant composite material and are bonded to the skins. The finished product is a door which is strong, stable, durable, secure and which is indiscernible from timber.

Outer Frame

Specially designed 70mm uPVC outer frame with dual seal weather proofing and a choice of thresholds to meet every requirement including new regulations for mobility access.


24mm toughened safety glass double glazed units with a choice of decorative glass to further enhance the appearance of your door. All doors come with high security multipoint locking with a choice of finishes that meet the requirements of the latest B.S.I. security standards. The insulating core consists of 100% CFC­free polyurethane which provides superior thermal performance and enhances the doors soundproofing.
