What is a composite door?
Composite doors are made from glass-reinforced polymer. A rigid, high-insulation foam core is surrounded by fibreglass and steel reinfircements, offering amazing durability – no rusting or warping – and incredible strength from such a lightweight material. They’re also virtually draught-free, and soundproof.
Coated with a textured woodgrain effect, they look and feel like wooden doors, and are available in a wide range of colours and styles. We take care of every aspect of the installation, fitting everything within a day.
What you get with a composite door from Roofline Design:
- 10-year guarantee against swelling, delamination or colour loss.
- Kitemarked hardware.
- Weather tested to BS6375.
- Secured by Design – approved by the Association of Chief Police Officers.
- Security Standard PAS 24 compliant.
- Multipoint hooked door locks.
- Stainless steel hardware, with a 25-year guarantee.
