Thermacore doors are manufactured from Glass Reinforced Plastic (GRP).  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.
