Before the glass is ordered
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.
Solar control
South-facing doors can overheat. Adding solar control glass at the same time keeps rooms cooler.
Glazing rules in Wales
Safety glass in critical locations
In Wales, safety glazing is covered by Approved Document N (glazing) under the Welsh Building Regulations rather than Approved Document K. Glass in doors up to 1,500 mm above the floor, in panes within 300 mm of a door up to 1,500 mm, and in other glazing below 800 mm should be safety glass or protected. Laminated and toughened glass are the usual choices.
Planning permission
In Wales the local planning authority decides whether a new or altered shopfront needs planning permission. Replacing glass in an existing frame usually does not, because the outside of the building looks much the same. Bollards or barriers on the pavement need consent from the highway authority, normally the council.

Patio and bifold door security glass in Gwynedd: questions
Which towns in Gwynedd do you cover?
We can arrange work anywhere in Gwynedd, including Bangor, Caernarfon, Holyhead and Pwllheli.
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.
