Secondary glazing for sash windows

As a result of their traditional heritage, most sash windows are created using single-glazed glass. As environmental demand and personal comfort have advanced over the years, more emphasis has been placed on energy efficiency standards and cost savings. However, with period and listed buildings, there’s still a need to preserve the original legacy and magnificence of the property. Research showed that in 2017, 23% of house buyers found Georgian properties most desirable – with sash windows being in the top 5 most popular features.

What is secondary glazing?

Often confused with double glazing, secondary glazing is different in a number of ways. Firstly, secondary glazing is a cost-effective alternative to its double-glazing counterpart – this is because secondary glazing is added as a supplement to the existing sash or casement window. In addition, modern secondary glazing can be visually attractive.
