The Mount Hawke Guide to Composite Doors (TR4)
By Cornwall Composite Doors · 5 October 1969 · 4 min read
Everything Mount Hawke homeowners need to know about composite doors — weather, colour choices, security ratings and what a local install actually looks like.
Why a composite door is warmer than what you have now
Almost every Mount Hawke door we replace fails on one of three things: air leaking around a warped timber frame, cold-bridging through single-glazed side panels, or a compressed seal that no longer touches the frame. A modern composite doorset is engineered to solve all three — insulated foam core, thermally-broken threshold, and multi-chamber frame with fresh compression seals top to bottom.
U-values and running costs
The composite doorsets we fit in Mount Hawke achieve U-values from 1.0 W/m²K including glazing — better than most walls fitted before 1990. In practice the hallway holds its heat, condensation stops forming on the inside face, and the heating comes on less. Homeowners routinely tell us the door has "made the whole house quieter" — that's the same air-tight seal doing double duty on noise.
Draught, noise and comfort
Every install in Mount Hawke includes fresh compression seals, an adjustable thermally-broken cill, and a multipoint locking mechanism that pulls the door into the frame at multiple points. The result is a door that clicks closed like a car door — no rattle, no whistle, no gap you can slide paper through.
