Trade uPVC casement windows in Lancashire

Ordering uPVC casement windows for jobs in Lancashire

If the property needs background ventilation, tell us which windows take trickle vents and we fit them in the frame head before dispatch, which saves routing them on site.

For first-floor bedrooms and other rooms that need an escape route, specify egress hinges on the relevant sash and give us the clear opening you need; we show on the quote the clear opening each sash gives, and your installer confirms it meets the escape requirement.

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.
