The largest sash width for our bi-fold doors is 1.2m which is dependent on the material, the overall frame size of the bi-fold door will be slightly larger than the amount of sashes multiplied by the sash width. We are able to make Aluminium doors anywhere from 1.6m to 9.6m and they can go up to 2.5m high!
We are able to quote oversized work if it meets the correct criteria on a special basis.
