Glass Options

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:
