Secondary glazing by Granada Glazing was used to improve the thermal efficiency of the apartment in a Grade II listed converted factory in Birmingham’s Jewellery Quarter.

“The property is all-electric, and it was still quite cold when I moved in,” said owner Jack Griffiths. “When I received my first electricity bill, I realised how expensive it would be to heat and that’s why I had secondary glazing installed on all of the front-facing windows to improve the insulation.”

Due to the building’s listed status, the period windows were retained to preserve the character and external appearance of the outward-facing elevations.

Granada Glazing supplied six arched lift units stacked on top of their horizontal sliding units. All were face fixed and powder coated in an Anthracite Grey finish to match the existing windows. Four windows were treated in the living/kitchen area and two in the guest bedroom.

As well as improving insulation, secondary glazing also reduces external noise and Jack has already noticed the acoustic benefits: “In the guest bedroom, I could really notice the reduction in the noise from the road. It’s not a busy road, but I could definitely tell as soon as the units were fitted.

“The secondary glazing is easy to operate. The units slide to one side for extra ventilation or can be removed for cleaning. In the summer, I removed a couple in the living room to let more air in and I could immediately hear the difference in sound from outside.”
