London is notorious for its strict conservation rule. So there is no need to replace the whole window as you can keep the existing frames with a little modification, only enjoy the benefits of a Double Glazed replacement. Founded in Windsor, Berkshire Double Glazed sash windows are being manufactured since 1979.

Modern double glazed sash windows are available nowadays, but depending on their aesthetic style, can be frowned upon. Traditional Double Glazed sash windows often attempt to mimic the original appearance through the use of non-functional munitions or "glazing bars", which are applied to the surface of the glazing, and give the appearance that the sash is made up of several smaller panels, whereas in reality, each sash consists of only one large double glazed sash window.

The benefits of such sash windows are:

• Reduce heating costs

• Reduce noise from outside

• To cut out draughts

• Provide extra security

Draught proofing sash windows provide all this without compromising the aesthetics of the original wooden sash windows.
