Sash Window Double glazing - thermal performance

Should you decide you would like double glazing sash windows, we would manufacture replacement sashes, an exact replica of the original sashes with a deeper rebate to house the wider unit, this would enable us to fit a slimline double-glazed unit which meets British Standards energy ratings and in return helps control the home temperature. 

Although there are extra costs in this process it's a small fraction of replacing the whole window and minimal disturbance to the window at the same time.  

We can supply a variety of options on double glazing .

Why not give us a call and let us give you a true cost on double glazing your sash window, we are confident you will be pleasantly surprised.
