Trade uPVC sliding sash windows in Herefordshire

Ordering uPVC sliding sash windows for jobs in Herefordshire

Sliding sash windows are made around the balances, so we size each window individually and choose the balance to suit the sash weight, including any acoustic or toughened glass you specify.

Most vertical sliders are ordered as straight replacements for timber box sashes. If the originals have horns, glazing bars or a particular meeting-rail height, note it on your schedule and the new windows are made to match.

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.

Before anything goes into production you get a written order acknowledgement with sizes, finishes and handing for every item. Check it carefully, because made-to-measure items cannot be returned if the sizes were wrong.
