New-town-property patio doors in Cwmbran

If you've got a 1960s new-town house on your hands in Cwmbran, the recurring problem when quoting patio doors is original 60s sliding aluminium frames cold-bridge and ice up internally. Tired 80s sliding aluminium doors that stick, lose heat and rattle in the wind is the paired issue you'll usually hear about at the same visit. Our spec here is thermally broken aluminium or reinforced uPVC with toughened safety glass to BS EN 12150. Stained-glass fanlights above the door can be re-set into a modern composite slab if intact, giving continuity across the swap. Stone walls hold thermal mass but radiate cold at the reveal edge; deep frames pull the cold plane further from the room. Roof canopies are usually mono-pitch and shallow — scaffold clearance rarely exceeds 2.1m above the frame head. New-build reveals are square to within 3mm — packing is minimal and the frame lands true first time. Bay window scaffold requires a chimney tie or through-bolt to the party wall — allow an extra hour on set-up. Estate covenants are searchable through the deed pack; we ask the client to confirm colour before ordering foil. Stone reveals need resin anchors, not plug-and-screw — dressed stone crumbles under mechanical fixings. Door head heights sometimes below 1.9m; a standard 1981mm slab needs trimming or a bespoke height ordering. Tile porches are laid on a lime bed that reacts poorly to modern silicone; we mask and use low-modulus polymer instead. Rear outshut kitchens often have flat felt roofs at 2.1m — glass and frame heights are set to clear the eaves.
