- Integral blind units replaced like for like where possible
- Units sized for sliding, French and bifold doors

Getting the right glass for your building
Integral blinds
Units with blinds inside the glass can be made with a laminated pane, but lead times are longer.
Laminated inner or both panes
A laminated inner pane is the usual security upgrade. On very exposed doors both panes can be laminated.
What the rules say 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.
Replacing glass in an existing frame
Welsh Government guidance says building regulations have applied to replacement glazing since 1 April 2002, which covers replacing windows and doors. Swapping only the glass or a sealed unit in an existing frame is generally treated as a repair. New glass in a critical location should still be safety glass, and the council's building control team can confirm anything unclear.

Patio and bifold door security glass in Cardiff: questions
Can you survey in Cardiff and nearby towns?
Yes. Surveys in Cardiff, Penarth and Caerphilly 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.
Do you work on aluminium bifolds?
Yes, on aluminium, uPVC and timber doors, provided the frame can take the new unit thickness.
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.
