Double glazed sealed units for Hertford jobs
Overall thickness has to match the frame rebate. A 28mm unit will not go into a frame glazed for 24mm, so check before you order.
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.
- Manufactured to BS EN 1279
- Made to size in common thicknesses such as 24mm and 28mm
- Aluminium or warm-edge spacer bars
- Low-E coated inner pane and argon gas fill

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.
Hertford is in England, so the building regulations for England apply. See the Hertfordshire page for a summary.
