Lift-out secondary glazing.
Lift-out secondary glazing units, designed for applications where limited access to the primary window is required. Units fit into a secured channel and consideration should be given to overall sash sizes to ensure the weight of glass is of manageable proportions. Each sash is manufactured with a double brush pile seal, which further increases the thermal and sound properties.
Can be supplied with arched or gothic head profiles and as stacking units. These units are used where the primary window is fixed or where a customer seldom requires access to open the window for ventilation.
Tested and approved to the following British Standards:
L10/58 Secondary glazing system
