Double Glazing Sash Windows

Traditional, Elegant and Slim-lite Double Glazed Sash Windows from Alpha Sash Windows.
New Slim-lite Double-Glazed Sashes into Existing Box Frames.

We can often just replace the sashes and repair the existing frames, to enable us to install Heritage Slim-lite Double Glazing into your sash windows. This has proven to be a very popular option, with more customers seeing the benefits of super-efficient slim-lite double glazing, whilst providing a cost- effective option in comparison to total replacement.

Our team has years of experience working with sash windows and have perfected upgrading older windows with brand new Heritage Slim-lite Double Glazing, whilst still retaining the character of the original windows.

Tradition finally meets technology.- keep the original architectural feel of your windows, but with all of the benefits of slim-lite double glazing.

The cost of slim-lite double glazing has come down considerably over recent years, and alongside our strong relationship with our supplier, retrofitting your sash windows with double glazing with Alpha Sash may not be as expensive as you may think!
