A patio door grille is a wide retractable grille fitted inside sliding patio or bifold doors. Closed, it protects a large glazed opening that is often out of sight at the back of the house; open, it folds into slim stacks so the view and access are unaffected.
Choices you can make
- Stacks positioned to clear handles and curtains
- Matched to aluminium, uPVC or timber frames
- Multi-leaf grilles for openings up to several metres
- Low-profile or recessed floor tracks
- White, black, anthracite or RAL
- Optional extra locking points for wide spans

Getting the right patio door grille for your building
Usage
If you open the doors every day, ask for a lighter-action grille with smooth runners.
Where it parks
Bifold doors stack their own leaves to one side; the grille stack should not fight them.
What the rules say in England
Bedroom and escape windows
Approved Document B (fire safety) expects many habitable rooms in houses, especially first-floor rooms, to have an emergency escape window with an unobstructed opening of at least 0.33 m², at least 450 mm high and 450 mm wide, with the bottom of the opening no more than 1,100 mm above the floor. We only fit grilles over escape windows with a release that opens from inside without a key.
Listed buildings and conservation areas
Listed buildings need listed building consent for works that affect their character, which can include internal grilles and their fixings. In conservation areas, councils look closely at anything fitted to the outside. We recommend speaking to the council's conservation officer before ordering.

Patio and bifold door grilles in Harrow: questions
Which areas near Harrow do you cover?
We can arrange work in Harrow and in nearby Wembley (2 miles), Northolt (3 miles) and Greenford (4 miles). Dates depend on installer availability.
Can I walk over the grille track?
Yes. Low-profile tracks are a few millimetres high, and recessed tracks sit flush with the floor.
Do patio grilles block the view?
When open, only a slim stack at each side. When closed, the lattice is open enough to see the garden clearly.
Will a grille get in the way of my bifold doors?
No. We plan the stack so the bifold leaves and the grille fold to positions that do not clash.
