Today’s aluminium windows and doors from are at the pinnacle of architectural glazing solutions. The inherent strength of the frame material allows the frame to be much narrower than the uPVC or timber alternatives and also means we can offer significantly larger glass areas.
Aluminium is a very stable material, keeping expansion and contraction with changes in the ambient temperature to a minimum. Where uPVC expands 3mm per metre, aluminium expands no more than 1mm per metre. This makes aluminium the only sensible choice of material for bi-fold doors, patio doors and large picture windows, where the opening may be several metres across.
