Trade uPVC sliding sash windows in Chesham

uPVC sliding sash windows for Chesham jobs

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.

• Run-through horns or plain sashes
• Georgian and astragal bar patterns
• Spiral or constant-force balances sized to sash weight
• Twin sashes sliding vertically in a uPVC box frame

Delivery to Chesham

Getting a price

Send your sizes as a schedule: one line per item with width, height, quantity and any options. A spreadsheet, a PDF or a clear photo of a handwritten list all work.

Open a trade account to order at trade prices. We ask for your business details and how you expect to order, and agree terms when the account is set up.

Measuring tip

Measure between the stone or brick reveals and from head to cill at several points. Sliding sashes depend on a square opening, so note any lean or out-of-square in the reveals on your schedule.

Regulations for jobs in Chesham

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.
