Trade aluminium windows in Blackburn

Aluminium windows for Blackburn jobs

Aluminium is stiffer than uPVC, so frames can be slimmer for the same window size, which is why it is often specified for extensions where the client wants as much glass as possible.

If the windows are part of an extension package with bifold or sliding doors, order them together and the colours and finishes are matched across the job.

• Thermally broken aluminium frame and sash with polyamide thermal break
• Trickle vents where specified
• Flush or stepped sash options
• Slim sightlines for larger glass areas

Regulations for jobs in Blackburn

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.
