Flying Mullion Windows
We all appreciate a fine view from a window even if it is only your own back garden! To take full advantage of stunning vistas or to simply watch your children or grand-children play, an unimpeded view is a real bonus.
A mullion is a vertical frame member onto which the casements close. A flying mullion is a mullion that is an integral part of one of the casements so that, when both casements are open, you have a clear and unobstructed view of the outside. When closed, it resembles a standard casement window and locks into place to give the same appearance as a conventional mullion.
The Flying Mullion window was first introduced as a means of fire escape and, although it can be used for aesthetic reasons, its principal purpose is still one of safety.
Just like our uPVC casement
windows, our flying mullion windows also enjoy a B* energy rating for your
comfort and economy.
* Based on our standard 4/16/4 sealed units.
