Before the glass is ordered
Solar control

Door hardware
Glass is only part of the picture. Worn rollers, missing anti-lift blocks or old locks are often worth fixing at the same visit.
Glazing rules in England
Security rules for new homes
Approved Document Q has applied to new homes in England since 1 October 2015. Easily accessible doors and windows, meaning any part within 2 m vertically of the ground or another accessible surface, should meet PAS 24 or an equivalent, and glazing in doors and in windows within 400 mm of a door should be laminated to at least BS EN 356 P1A. It does not apply when you change the glass in an existing home, although it is a sensible benchmark.
Planning permission
Changing the glass in an existing window or shopfront does not usually need planning permission, because the building looks much the same afterwards. A new or altered shopfront, or security features added to the outside of a building, may need planning permission from the council. Bollards or barriers on the pavement need the highway authority's consent, which is normally the council.

Patio and bifold door security glass in Chiswick: questions
Can you survey in Chiswick and nearby towns?
Yes. Surveys in Chiswick, Acton and Barnes are booked around installer availability.
Is patio door glass already safety glass?
It should be, because doors are critical locations. Most is toughened, which is safe but not secure. Adding a laminated pane makes it both.
Can you replace just one pane of a bifold?
Yes. Each leaf takes its own unit, so we can upgrade one leaf or all of them.
Will laminated glass make my bifolds harder to open?
Units are slightly heavier. We adjust hinges, rollers and carriages after fitting so the doors run smoothly.
