- Units sized for sliding, French and bifold doors
- Low-E, argon and solar control glass options
- Roller, carriage and hinge adjustment after fitting

What to think about first
Integral blinds
Units with blinds inside the glass can be made with a laminated pane, but lead times are longer.
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.
Consents and safety: England
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.
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 Greenwich: questions
Can you survey in Greenwich and nearby towns?
Yes. Surveys in Greenwich, Blackheath and Canary Wharf are booked around installer availability.
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.
Do you work on aluminium bifolds?
Yes, on aluminium, uPVC and timber doors, provided the frame can take the new unit thickness.
Can sliding doors be lifted out?
Older sliding doors without anti-lift blocks can be. We check for this at the survey and can fit blocks at the same visit.
