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.
