Aluminium Bi-Fold Doors in Barnet

Bi-fold doors made for Barnet homes
North London's greenest borough has the space that bi-folds love. Barnet's inter-war semis and detached homes, and the grander houses of Totteridge, Mill Hill and Hampstead Garden Suburb, typically enjoy wide, deep rear gardens. A full-width bi-fold across a rear or wrap-around extension opens the kitchen-diner onto the lawn and turns the back of the house into a light-filled garden room.
We use thermally broken aluminium with low-E double glazing so these garden-facing rooms stay warm and efficient through the winter, and low thresholds for easy level access to the patio. Wide openings are structurally surveyed, and every set is made to measure and fitted by our own installers.

Why aluminium
Slim frames, wide spans, year-round warmth
Thermally broken aluminium is strong enough for the wide openings Barnet homes are known for, yet slim enough to keep sightlines minimal and glass maximised. Low-E double glazing, weather-rated thresholds and multi-point locking mean the doors look after comfort and security as well as light.
