We know conservation areas

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. There’s no need to feel restricted – our Lambs Tongue and Ogee profile moulds in our Heritage style sash and case timber windows have been used in traditional buildings, Listed Buildings and Conservation Areas for years.

Our windows are approved for Grade A, B and C Listed buildings for Conservation Areas.

We work on single projects, where sash and case windows need to be replaced or upgraded from single glazing to double glazing for higher thermal performance. With customers adding an extension to a property with existing sash and case windows, and with developers on bigger developments, renovation of mills into residential apartments for example, and new build properties. .

Our double glazed units are filled with Argon gas to increase the thermal properties and we use warm edge spacer bars and soft Low E glass. And we can also supply with Krypton or Xenon for increased thermal properties.
