Our composite door outer frame is 16x more rigid than reinforced PVC-u, eliminating door ‘bounce’ and providing a premium feeling door ‘experience’ that homeowners love.
Frames to suit 44mm & 48/49mm door slabs. With low threshold options tested to the requirements of Part M. Thresholds can also be run continuously under sidelights if required.
Both thresholds can accommodate a mechanically jointed ‘T’ transom/mullion, giving slimmer sightlines when doors are configured with sidelights. The system has also been designed to easily incorporate toplight/sidelight combinations.
Features such as threshold cover strips that conceal fixings and universal sealable end caps, mean that delivering quality installations using the Prestige Composite Door frame couldn’t be easier, perfect for busy installation teams.
Our patented construction method does away with the need for crimping and specialised machinery, drastically reducing waste while speeding up manufacturing.
Prestige’s Thermlock® core provides exceptional thermal performance using multiple insulating chambers to create class leading thermal performance, perfect for meeting the requirements of Part L.
