Our 40mm Triple glazed window and entrance door system continues to prove popular with our customers.

Many people ask what it looks like. Well the frames are the same as our douible glazed window system with the exception of a flat style beading to the inside to make up the additional 12mm of sealed unit depth.

The sealed unit spacer bar of course looks deeper yet the centre piece of glass that makes up the unit simply shows as a line when you look into the sealed unit.
