Secondary Glazing

We use the different options for different reasons and each has a place in our work. Timber secondary glazing we find works best for large hinged projects, while aluminium secondary glazing fits better in projects where slim profiles are required. We also use and recommend magnetic secondary glazing in many areas of our historic work, as it works well with stone frames, as no drilling is required, and it is far less visible than aluminium and timber which both come with frames to house the units. English Heritage have approved the use of our magnetic secondary glazing on certain Grade II listed buildings.
