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.

- Multi-leaf grilles for openings up to several metres

Getting the right patio door grille for your building
Colour
Anthracite grilles sit quietly against grey aluminium frames.
Usage
If you open the doors every day, ask for a lighter-action grille with smooth runners.
What the rules say in Wales
Bedroom and escape windows
Wales has its own Approved Documents under the Building Regulations. Approved Document B for Wales sets out escape window provisions for dwellings broadly in line with England's, including minimum opening sizes. We only fit grilles over escape windows with a keyless internal release.
Grilles inside the glass
A grille fitted inside the glass does not normally need planning permission in Wales, as it does not materially change the outside of the building. If the building is listed, listed building consent may still be needed.

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