Premium Aluminium Bi-fold Windows

Aluminium bi-fold windows suit both traditional and modern homes, folding back easily to maximise your living space. For a large area, opening bi-folds are hard to beat and are a good alternative to sliding windows. They can be designed in a range of configurations to suit your space. To allow for clear walkways, decks and outside areas the innovative lay-back bi-fold windows from Altherm fold flat against walls.

We recommend double glazing for all our aluminium windows. For more information regarding double glazing view our glass options.
