Energy Efficient

Aluminium bi-fold doors provide excellent thermal insulation. They are thermally broken, so they will not allow heat to be lost through the frame, helping to keep your home warm and comfortable.

They come with a polyamide thermal barrier to reduce heat loss and are available in either 28mm double glazed units or 36mm triple glazed units. The double glazed option is available with integral blinds and gives a U value of 1.8 W/m²K, the triple glazed unit gives an overall frame U value of 1.4 W/m²K.

Our aluminium bi-fold doors also come with high quality EDPM rubber gaskets and weather brushes to aid weather proofing, meaning your home is protected from the elements
