Trade steel-look aluminium windows in Boston

Steel-look aluminium windows for Boston jobs

Black and dark grey are the usual colours, but any RAL colour can be powder coated if the design calls for it.

They are aluminium rather than steel, which keeps the weight down and allows a thermal break. Where a heritage specification calls for real steel, tell us and we will say whether we can quote it.

• Matching doors and screens available
• Narrow glazing bars in grid patterns
• Powder coated, usually black or dark grey
• Slim thermally broken aluminium profiles

Regulations for jobs in Boston

Replacement windows in England should meet Approved Document L: a U-value of 1.4 W/m²K or a Window Energy Rating of band B. Approved Document F expects background ventilation to be no worse than before, which usually means trickle vents. Glazing in critical locations must break safely, be robust or in small panes, or be permanently protected under Approved Document K, which in practice usually means toughened or laminated safety glass. Rooms that need an escape route may need an escape window under Approved Document B. Replacing windows is notifiable building work: the installer self-certifies through a competent person scheme such as FENSA or Certass, or the work goes through building control.
