- Fold to one or both sides
- Mesh or solid infill panels on request

What to think about first
Look
Bi-folds read as a screen rather than a lattice, which suits modern interiors.
Floor guide
A bottom guide keeps the leaves aligned. Recessed guides keep the floor flush.
Consents and safety: England
Grilles across exits in business premises
In workplaces and other non-domestic premises, including the common parts of blocks of flats and HMOs, the Regulatory Reform (Fire Safety) Order 2005 makes the responsible person keep escape routes and emergency exits available and easy to open while people are present. A grille across an exit should be unlocked and parked open whenever the building is occupied, and covered in the fire risk assessment.
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.

Bi-folding security gates in Derby: questions
Can you survey in Derby and nearby towns?
Yes. Surveys in Derby, Belper, Ilkeston and elsewhere in Derbyshire are booked around installer availability.
What is the difference between a bi-fold gate and a retractable grille?
A retractable grille uses a scissor lattice that concertinas; a bi-fold gate uses rigid hinged leaves that fold flat. Bi-folds look more architectural; retractables fold into a narrower stack.
Do bi-fold gates need a floor track?
They need some bottom guidance, which can be a recessed channel or discreet floor pins rather than a raised track.
How wide can a bi-fold gate be?
From a single doorway up to several metres, split to fold both ways on wider openings.
