Our Fixed secondary glazing units are the most inexpensive and easy to fit style of secondary glazing we offer. An effective method of reducing noise and heat loss, and considered to be the most easily reversible change. It has pre-drilled countersunk holes and is very popular in conservation areas, especially in leasehold properties where changing the existing windows maybe uneconomical or an impossibility.
Fixed secondary glazing is part of our economy system and is the slimmest style of secondary glazing we offer, at just 20mm wide. The wool pile on the back of the frame helps create a good seal between the existing window, preventing draughts and blocking out sound.
They have no opening mechanism, no subframe and is simply face fixed directly onto the existing windows. This style of secondary glazing will provide no access to the prime window.

Our standard glass for our secondary glazing is 4mm clear float glass. We have a huge variety of glass available for our secondary glazing and it is possible to tailor your secondary glazing to your individual requirements. You can specify glass for improved sound insulation, thermal performance or security. Different thinnesses of glass are available for greater thermal and sound insulation. See examples of the different glass we can offer below:
Thickness | Glass | Properties |
---|---|---|
4mm | Float Glass | Can expect good improvement in sound and heat insulation. (a.k.a. Annealed Glass) |
4mm | Obscure / Patterned / textured Glass | Specified for aesthetics and privacy (e.g. in a bedroom or bathroom). Read More... |
4mm | Toughened Glass | Same as float glass with added safety and security. |
6mm | Float Glass | For better performance in sound and heat insulation when compared to 4mm float. Has greater strength than 4mm glass for use in larger panels. (a.k.a. Annealed Glass) |
6mm | Toughened Glass | Same as 6mm float glass, but provides added safety and security. |
6.4mm | Laminated Safety Glass | For superior sound and heat insulation and far superior safety and security. |
