Secondary Glazing

Secondary glazing can be a great way to improve the energy efficiency and noise reduction of a primary window and it can also reduce dirt ingress,

We manufacture & install special hardwood secondary glazing that is very slim & discreet. We offer this with a fully hand painted or sprayed finish.

To maximise the improvements, we would always recommend having the primary windows & doors upgraded first if possible.
