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.

Getting the right patio door grille for your building
Where it parks
Bifold doors stack their own leaves to one side; the grille stack should not fight them.
Colour
Anthracite grilles sit quietly against grey aluminium frames.
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.
Grilles inside the glass
A grille fitted inside the glass does not normally need planning permission, because it does not materially change how the building looks from outside. If the building is listed, listed building consent may still be needed.

Patio and bifold door grilles in Hounslow: questions
Which areas near Hounslow do you cover?
We can arrange work in Hounslow and in nearby Isleworth (1 mile), Heston (1 mile) and Richmond (2 miles). Dates depend on installer availability.
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.
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.
How long does fitting take?
A typical set of patio doors takes half a day once the grille is made.
