Bi-fold Doors

Aluminium Bi-fold doors are hugely popular in New Zealand, they allow for a dramatic wide opening offering unrestricted access to outdoor areas that Kiwis love, especially when combined with sliding windows or bi-fold windows. They enable you to open up your living and family areas to give level access to decks or patios increasing your living space. The price of bi-fold doors makes them an affordable option.

Altherm aluminium bi-fold doors easily cope with a large opening span with panels that glide easily along the bottom track. All bi-fold doors are available in double glazing and come in a number of different door combinations to suit your home. Stacking doors open neatly to each side, or, for unobstructed access, choose Altherm’s lay-back bi-fold doors swing back against adjoining walls, keeping the outdoor space clear for entertaining and playing children.
