Before the glass is ordered

Glass is only part of the picture. Worn rollers, missing anti-lift blocks or old locks are often worth fixing at the same visit.

Solar control

South-facing doors can overheat. Adding solar control glass at the same time keeps rooms cooler.

Glazing rules in England

England

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.

Safety glass in critical locations

In England, section 5 of Approved Document K treats glazing in doors and in side panels within 300 mm of a door edge, from floor level up to 1,500 mm, and any other glazing below 800 mm, as a critical location. Glass there should break safely, be robust, or be guarded. Laminated or toughened glass meeting BS EN 12600 class 3 is the usual answer, rising to class 2 for door and side-panel panes wider than 900 mm.

Patio and bifold door security glass in Derby: questions

Which areas near Derby do you cover?

We can arrange work in Derby and in nearby Belper (7 miles), Ilkeston (8 miles) and Heanor (8 miles). Dates depend on installer availability.

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.

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.
