Double glazed sealed units for Welwyn Garden City jobs
Sealed units are made to the exact glass size, so the measurement is the size of the unit itself. When replacing a misted unit, measure the old unit once the beads are off.
Glass in critical locations, such as doors, side panels and low-level glazing, must break safely, be robust or be protected; in practice that usually means toughened or laminated glass. Mark those units on your schedule.
- Made to size in common thicknesses such as 24mm and 28mm
- Manufactured to BS EN 1279
- Low-E coated inner pane and argon gas fill
- Toughened, laminated, obscure and acoustic glass options

Trade accounts are open to installers, builders, developers, landlords and property businesses. Apply online and your account terms are agreed when it is opened.
Measuring tip
Measure the glass, not the frame: remove the beads and measure the existing unit, or measure the rebate and deduct the glazing clearance. Give width first, then height, and the overall unit thickness.
Regulations for jobs in Welwyn Garden City
Under Approved Document K, glazing in critical locations (doors, and side panels within 300mm of a door, up to 1500mm above floor level; other glazing below 800mm) must break safely, be robust or in small panes, or be permanently protected. Toughened and laminated safety glass are classified to BS EN 12600. Replacing only the glass in an existing frame is generally treated as a repair rather than notifiable work.
