Energy efficient secondary glazing

Here’s the latest installation of our highly efficient “heritage” secondary glazing. Perfect for listed buildings and conservation areas where double glazing is not permitted or for where noise ingress needs to be drastically reduced. 

We have installed these secondary glazing units after initially restoring and draught proofing the original sash windows in this grade 2 listed property in Sefton Village, Merseyside.  

Incorporating the latest “Low E” glass and draught seals, our secondary glazing outperforms traditional double glazing, while also reducing noise pollution. 

With many options available including custom colours, we can install secondary glazing to blend in with your existing windows.

Arched / Curved sash windows

We can produce our double glazed sash upgrades with arches / curves to match your existing frames. When we take our final measurements prior to manufacture, we will take a template of your existing window frame and produce our double glazed sashes to fit perfectly.
