Deep Bottom Rail

Alas, these days very little attention is given to a window’s sight lines or how it is framed in an opening.

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.
