What are composite doors made from? Unlike uPVC plastic doors, composite doors are made from several different materials that are sandwiched and glued together.
This action takes place under extremely high-pressure conditions to ensure the materials bond together strongly. The materials used are also specifically selected due to their properties and to counteract common flaws found in single-material doors.
The resulting product is a door that is much thicker than your standard uPVC door. Composite doors are typically manufactured to a thickness of 44mm, whereas uPVC doors are 28mm in most cases. This adds increased strength, durability, security and weather resistance.
