Our Story

Founded with a passion for helping homeowners solve noise and thermal efficiency problems without compromising their property's character.

From Humble Beginnings

SecondaryGlazing Pro was founded in 1998 by David and Margaret Thompson, who were frustrated by the noise from a busy road outside their Victorian terrace home. Unable to replace the original sash windows due to conservation restrictions, they discovered secondary glazing as the perfect solution.

After experiencing the dramatic improvement in comfort and energy efficiency, they realized many other homeowners faced similar challenges. What started as a solution for their own home became a mission to help others across the UK.

Today, we're proud to be the UK's leading secondary glazing specialists, with a team of expert technicians, a state-of-the-art manufacturing facility, and thousands of satisfied customers nationwide.
