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
Usage
If you open the doors every day, ask for a lighter-action grille with smooth runners.
Track
A low-profile track keeps the threshold easy to walk over. Recessed tracks need a little floor work.
What the rules say in England
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.
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.

Patio and bifold door grilles in Harpenden: questions
Which areas near Harpenden do you cover?
We can arrange work in Harpenden and in nearby St Albans (5 miles), Luton (5 miles) and Hemel Hempstead (6 miles). Dates depend on installer availability.
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.
Can the grille be fitted outside the patio doors?
It can, but inside is usual because the grille is protected and the outside of the house stays the same.
Can I walk over the grille track?
Yes. Low-profile tracks are a few millimetres high, and recessed tracks sit flush with the floor.
