Secondary Glazing

We supply top quality aluminium secondary windows for domestic or commercial applications.

This is an excellent product and alternative to a new double-glazed window where building restrictions or listings need to be met.

Secondary glazing is a very cost-effective method of providing thermal insulation and efficient soundproofing for all types of windows and doors.

Our standard secondary glazing substantially reduces the heat loss from single glazing and there are options to provide increased energy efficiency.


  • Excellent for noise reduction
  • Improved energy efficiency
  • Reduced heating bills
  • Condensation control
  • Added security
  • Years of robust, trouble-free service
  • A discreet, unobtrusive finish frame

If you would like further information about our secondary glazing and to arrange a free, no-obligation quote for your requirements, please contact us using the number above or using the contact form.

Super friendly and helpful team, and very reasonably priced stock. We picked up some greenhouse glass following the storm - so glad to have this local business. We’ll be back for more glass/ mirror bits and pieces!

Excellent service and a good price. I had some single pane glass break that needed replacement cutting, Graham was able to arrange a replacement pane the same day. Would highly recommend!

Graham has just been to repair 6 panes on our old greenhouse and he was brilliant. He did his upmost to help pull the old greenhouse into shape including moving other panes back into place that had slipped, fixing the door that was flapping around and delivered excellent customer service and was very friendly. I would definitely recommend him.
