Permanently fitted and easily accessible
Ideal for larger glass expanses

Our fixed units are exactly what the name would suggest, featuring a piece of secondary glazing that is permanently fitted to a primary window. If a permanent fitting is not suitable, the unit can be fitted with turn button releases to enable removal for cleaning and maintenance. It’s an ideal option for when space is limited, or when minimal access to the primary window is required. For this reason, our fixed units are incredibly popular in large-scale commercial projects.
