Trade uPVC sliding sash windows in Essex

Ordering uPVC sliding sash windows for jobs in Essex

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.

Sashes tilt in for cleaning, which matters on upper floors of flats and terraces where the outside of the glass cannot be reached from a ladder.

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.

We do not start manufacturing until you have approved the order acknowledgement. It repeats each size, colour and opening direction so you can check it against your survey.
