Triple glazing in Walthamstow Village

The housing in Walthamstow Village is largely Victorian terraces with sash windows and a few much older buildings. On Victorian terraces, triple glazing is best paired with wall and loft insulation improvements, since windows alone will not solve heat loss through solid brick walls.

Detached houses and cottages with exposed or north-facing elevations can benefit from triple glazing on those sides, even if double glazing is used elsewhere. Triple glazed units are thicker and heavier, so they rarely suit slim traditional profiles in conservation areas, where secondary glazing may be a more acceptable alternative.

The Village is a conservation area, so Waltham Forest Council expects changes to front windows and doors to suit the historic style. We check the guidance and, where needed, help with the planning side before work begins. The streets are narrow and parking is tight, so we plan fitting days carefully.

Triple glazing adds a third pane of glass and a second sealed gap, improving insulation and comfort beyond standard double glazing. It suits homeowners aiming for very high energy efficiency, people living near busy roads, and homes undergoing deep retrofits where walls, roofs and windows are all being upgraded together.

• Warmer glass surface near windows
• Extra layer helps reduce outside noise
• Suits low-energy and retrofit projects
