Double glazing in EN7

In homes built from the 1980s onwards, misted or blown double glazed units are common, and replacing just the glass often restores performance without new frames.

Original 1930s leaded lights can be replicated within double glazed units, so you keep the decorative pattern while gaining modern insulation and quieter rooms. Detached homes have more external walls and windows losing heat, so upgrading every window to modern double glazing at once gives consistent comfort throughout.

Many homes here have had their windows replaced at least once, and the oldest units are starting to fail. Bungalows and detached houses often have large picture windows and patio doors. EN7 is about 7.3 miles from our Edmonton factory, via the A10. Cuffley, nearby, falls under EN6.

Double glazing uses two panes of glass with a sealed, insulating gap between them, cutting heat loss, draughts and condensation compared with single glazing. We fit it in new windows and doors or as replacement sealed units, suiting almost every home, from older properties still single glazed to houses with failed units.

• Less condensation on the glass
• Quieter rooms than single glazing
• Toughened and laminated safety glass options
