Deep Bottom Rail

Traditionally, the lower rail of the bottom sash was often made from 4″ or 5″ timbers and planed to about 100mm. This was substantially heavier (deeper) than the side members or mid-rail because it had to carry more weight than the upper sash.

While it is far quicker, cheaper and easier to weld together profiles of equal size, it would not look traditional. All Masterframe windows have this thicker, butt jointed deep bottom rail as standard, mechanically joined by hand in our factory.
