Trade aluminium windows in Cornwall

Ordering aluminium windows for jobs in Cornwall

Every aluminium window is powder coated to the RAL colour you choose. Dual colour lets you have, for example, anthracite outside and white inside on the same frame.

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.

Building regulations in England

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.

Every order is confirmed in writing first. The acknowledgement lists each item exactly as it will be made, so any mistake in a size or handing can be caught before manufacture.
