We manufacture our SlimBar windows using astragal overlay cassettes. Which gives all the benefits of a modern double-glazed window with high thermal efficiency and the appearance of a traditional sash and casement window. Come and see the difference in our showrooms.

Our Heritage double-glazed units look just like single glazing due to their clever narrower cavities between the panes of glass. (4mm Glass, 4mm gas filled cavity, 4mm Glass).

They are an ideal choice for listed properties with their slim sightline. Please note that we can also accommodate single glazing where this is required.

We’re proudly knowledgeable about Scotland’s sash and case timber windows, their origins, influences and conservation laws. So, you’re in safe and very talented hands.
