How we specify

The right product route is chosen per project

Exact specification (U-value, sizes, weights, security class, finish) is confirmed per project at quote, selected to suit the trade brief.

It means you lead with the outcome: light, security, clean sightlines, usable openings, buildable details and a specification that suits the drawings.

More on how routes are specified: security and PAS 24 routes and energy efficiency and U-values.

Common questions

How wide can an aluminium bifold door open up?

Aluminium bifolds fold flat against the reveal, clearing the full span. Runs go up to 14 leaves where specified, with individual leaves up to 1.2 m wide and 3.0 m tall at up to 130 kg each. Clear opening depends on panel count and weight. Confirm the figure for your structural opening at quote.

What panel split and maximum panel sizes should I specify?

Aluminium bifolds run splits from 2 up to 7 leaves, folding left, right or from the centre. Each leaf reaches up to 1.2 m by 3.0 m at up to 130 kg, capped by glazing weight. Glass runs 22 to 46 mm, double or triple. Heavier glass cuts leaf size, so set the split against glass at quote.

Can a bifold have a traffic door and a low threshold?

Yes. The traffic door is an access leaf that swings like a single door for daily use, so the whole run stays folded. Pair it with the 20 mm thermally broken low-threshold option for a near-level, pram and wheelchair-friendly crossing. Weather is rated to air permeability Class 4, so weigh exposure at quote.

How secure are aluminium bifold doors?

Aluminium bifolds carry multi-point locking and can be specified to PAS 24 tested-security routes, including PAS 24:2025, with laminated glass options. Hinges, shootbolts and the traffic-door lock engage on closing, durability tested to 50,000 cycles. See security for the routes, then confirm locking and glass at quote.

What finishes and U-values can I specify, and can homeowners buy direct?

Bifolds come in full RAL, dual-colour and anodised-style finishes, with whole-door U-values from 0.9 W/m²K where specified. Confirm the whole-unit Uw at quote. We supply trade only; homeowners are routed to vetted installers via find an installer. Trade buyers request pricing at quote.
