Bespoke Composite Doors

The composite door’s technology and materials are advanced, but the appearance replicates traditional timber doors. The grain, the detail, the styles – everything is perfect for your installation.

Our composite doors also offer everything the homeowner has come to expect from a composite door solution. A beautiful, low-maintenance skin that minimises shrinking and expansion. Impeccable security credentials bring peace of mind. It goes without saying excellent thermal efficiency helps to keep the cold out and the warmth in. Plus, the robust series of materials can also help with noise insulation, so our composite doors could help keep your home quiet and peaceful.

Harsh weather conditions can be withstood with ease, as our composite door colours can resist fading for years with minimal upkeep. Homeowners can rest easy knowing they won’t have to repaint our durable composite doors.

Composite doors for the trade

Our composite doors can provide an incredible level of security, aesthetics, and thermal performance.

Manufactured from GRP (Glass Reinforced Plastic), Thermacore Doors are compression moulded to give a high-definition panel design with an authentic timber appearance which is unaffected by variations in temperature.

The stiles and rails are composed of a water-resistant polymer, which are bonded to the skin and then filled with an insulating core of 100% CFC- free polyurethane.
