Double glazing in EN4

Detached homes have more external walls and windows losing heat, so upgrading every window to modern double glazing at once gives consistent comfort throughout.

Original 1930s leaded lights can be replicated within double glazed units, so you keep the decorative pattern while gaining modern insulation and quieter rooms. Many Victorian terraces still have single-glazed sashes, and moving to double glazing is often the biggest single comfort upgrade, whether through new windows or secondary glazing.

Big detached homes need wide-span doors and strong security; older terraces need windows that match the period. The East Coast Main Line runs past New Barnet and Hadley Wood. EN4 is about 5.5 miles from our Edmonton factory.

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.

• Warmer rooms and lower heat loss
• Quieter rooms than single glazing
• Toughened and laminated safety glass options
