What is Secondary Glazing?

The units are tailor made to match the existing window to form a double window or ‘Double Glazing’. The existing windows remain unaltered and in most cases, curtains or blinds are unaffected. Secondary glazing is designed to reduce noise and cut cooling costs by adding another window inside your existing external windows. It is easy to fit and is cost effective and is very popular in high rise apartments where the existing external windows cannot be changed.
