Secondary Glazing

We carry out comprehensive installations of secondary glazing to domestic and commercial properties based throughout Essex and East London.

A cost effective and quickly installed alternative to double glazing, secondary glazing adds a single glazed layer of glass to the existing window frame, providing similar double-glazed benefits such as improved heat insulation with reduced outside noise and condensation. Secondary glazing can also be supplied and installed with acoustic glass, designed to cut back on noise even when next to busy roads or an airport, and it can also be added to many double glazed installations as tertiary glazing, creating three layers of glass for incredible acoustic insulation.
