Trade uPVC flush sash windows in Essex

Ordering uPVC flush sash windows for jobs in Essex

Because the sash sits inside the frame rather than over it, flush sash windows need slightly different frame depths and fixing positions. We confirm the frame depth on the quote so you can plan the fixing before the windows arrive.

A flush sash window is usually chosen for how it looks, so the details matter: hinge type, handle style, glazing bars and the woodgrain finish are all listed separately on your quote so nothing is left to assumption.

Specification at a glance

• Butt hinges or friction hinges
• Trickle vents concealed in the frame where specified
• Mechanically jointed or welded corners depending on the system
• Matching run-through sashes for a balanced sightline
• Double glazed as standard, triple glazing available

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.
