Doors

Commercial doors that open up your space

For cafés, restaurants, showrooms and retail frontages, aluminium bi-fold and lift & slide doors open up an entire wall to connect inside and outside, then close to a secure, weathertight and thermally efficient seal. We survey, supply and install commercial-grade systems with polyamide thermal breaks, multi-point locking and large glazed panes, specified to PAS 24 security and BS 6375 weather performance where required. Commercial profiles and hardware are engineered for the higher cycle counts and larger sizes that trade use demands.

Your options

Bi-Fold Doors

Aluminium leaves hinged together that concertina and stack to one or both sides, opening most of the aperture. Choose these to fully open a café or retail frontage and create seamless indoor-outdoor trading, with a single traffic leaf for everyday access.

Lift & Slide Doors

Large sliding panels on a mechanism that lifts each sash off its seals onto rollers for effortless movement across wide spans. Choose these for very large glazed openings, slim sightlines and expansive fixed glazing that glides rather than folds.

Why it matters

Why retailers choose Swift for doors

Open-up frontage

Transform a retail or hospitality space by opening most of the wall for indoor-outdoor trading and kerb appeal.

Thermal efficiency

Polyamide thermal breaks and modern glazing cut heat loss; well-specified systems reach low U-values to support Building Regulations compliance.

Commercial-grade durability

Heavier profiles, gearing and hardware built for frequent daily use and larger, heavier leaves than domestic systems.

Security when closed

Multi-point locking, high-security cylinders and PAS 24-tested options protect the premises out of hours.

Weathertight sealing

Tested to BS 6375 / BS EN 14351-1 for air, water and wind resistance on exposed frontages.

Accessible thresholds

Low or flush threshold options support level, wheelchair-friendly access in line with accessibility guidance.

FAQs

Common questions

What is the difference between bi-fold and lift & slide?

Bi-folds fold and stack to clear most of the opening, best for fully opening a frontage. Lift & slide doors glide large panels past each other with slimmer sightlines and bigger individual panes, but one panel’s width always remains glazed. Bi-folds maximise clear opening; lift & slide maximises glass and view.

Are these different from domestic doors?

Yes. Commercial-grade systems use heavier profiles, hardware and gearing rated for higher daily cycle counts and larger, heavier leaves, and are specified to withstand trade footfall.

How secure are they when closed?

Multi-point locking, intermediate shoot-bolts and high-security (3-star / TS007) cylinders are standard options, and doorsets can be PAS 24 tested. Laminated glass is normally required for full PAS 24 compliance.

Are they warm enough for year-round trading?

Yes, polyamide thermal breaks and modern glazing deliver low U-values, and well-specified systems support Approved Document L compliance for year-round comfort.

Can I have level access for wheelchairs and trolleys?

Yes, low or flush threshold options provide near-level access in line with Approved Document M / BS 8300; we balance accessibility against weather exposure at survey.
