Ordering uPVC casement windows for jobs in County Durham
Casements cover most replacement work in the UK because almost any opening can be laid out with a mix of side-hung, top-hung and fixed lights. You give us the sizes and opener layout and each window is made to that schedule rather than chosen from a list of standard sizes.
Every window on your order is listed separately on the quote with its size, layout, glass and finish, so you can check the whole job line by line before anything is put into production.

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.

How do I get trade prices for County Durham?
Send your schedule through the quote form or by email, and apply for a trade account if you do not already have one.
Do the windows meet building regulations?
They can be specified to meet the thermal values in the building regulations for where the job is, with trickle vents, safety glass and escape hinges added where the regulations call for them. Your installer is responsible for any notification or approval the job needs: in England and Wales usually through a competent person scheme; in Northern Ireland through council building control; in Scotland, replacement windows in a house do not normally need a warrant but must meet the standards.
Are the windows supplied glazed?
Windows can be supplied glazed or with the units packed separately for site glazing. Tell us which you prefer when you order; larger windows are often easier to handle with the glass out.
