Bi-Fold Doors
Multi-leaf folding doors that open up entire walls
Bi-fold doors fold and stack against a single wall to deliver the widest possible open aperture — connecting a kitchen, living or garden room to the outside in a way nothing else can match. Specified properly, in aluminium or premium uPVC, they are one of the highest-impact upgrades available to any UK home.
SGS specifies Smart Visofold aluminium bi-folds for most premium projects — Smart's flagship folding system, with stainless-steel running hardware engineered for a 50,000-cycle life and configurations available up to 7m+ wide and 2.4m tall.
