Rules & regulations
- Building regulations cover the glazing (safety glass) and thermal performance, FENSA/CERTASS self-certification again
- Widening the opening means structural work: engineer's calcs and building control
Snap tips
- Honest comparison: sliders give more glass and cost less per metre of view, bifolds win when you want the wall fully open
- A level threshold needs drainage detail outside; ask how they'll handle it
