Our Standard Finishes

Each system is pre finished leaving little to do on site after installation.

The paint systems we use are carefully selected to increase the lifespan of our products and make maintenance easier.

Painted Systems

Each system undergoes the following process to ensure a perfect finish that will last.

  • 3* Wood Preserver (All timbers are preservered to reduce the risk or blue funghi and insect attack)
  • Knotting Solution (All knots and resinous timbers are treated to prevent bleed through)
  • End Grain Sealer (All end grain sections and weak spots are sealed to reduce moisture intake in these areas)
  • Primer (all timbers are primed to aid paint adhesion and prevent tannin bleed from certain oily timbers)
  • Undercoat (Flexible oil based undercoat by Johnstones is applied)
  • Top Coat (Flexible top coats by Johnstones are applied, available in Satin, Gloss and Eggshell.

All our products are hand painted to ensure a finish which not only looks traditional but can be reapplied time and time again as required. We do not spray any of our products as we find that spray finishes give a plastic look and detract from the natural timber look.

Varnished & Stained Systems

Each system undergoes the following coating process

  • 3* Wood Preserver (All timbers are preservered to reduce the risk or blue funghi and insect attack)
  • End Grain Sealer. (End grains are coated to reduce moisture intake)
  • Base Coat (A base coat is applied if required, based on timber and coating used)
  • Top Coat (2 coats are applied to provide the neccessary weathering)

Most varnishes and stains will require recoating after the first year of weathering. This is perfectly normal and usually requires a quick coat on the outside of the system only.



Take A Look At The Specifications

Technical Details

Maximum panel height: 3000mm (4000mm available as special order)
Maximum width per panel: 1200mm

Choice of Locking mechanisms. Flush Bolt or Shoot Bolt options on bi folding pairs. Winkhaus ‘Secured By Design’ multipoints on end doors.
Ultra-smooth top hung and bottom running options.

Colour Options

Our products are hand painted and can be coated in a colour or finish of choice.

As standard we use the Johnstones Flexible paint system for opaque systems  and Osmo UV Protection Oil for stained/varnished systems. This is purely due to our experience as it provides the neccessary protection from weathering. However if you need us to match existing joinery you have then we are happy to use a paint system of your choice.

Brio Hardware

Brio offer 316 Stainless Steel hardware suitable for panels upto 150kg. The 316 is a marine grade stainless steel which is guaranteed for 10 years even in coastal locations. 

The stainless ball bearing hinges ensure a smooth operation throughout the lifespan of the product. 

Brio offer hardware in 4 finishes. Satin Stainless, Polished Stainless, PVD Black and PVD Brass. 

Head tracks are Anodised Aluminium while the sills have a few more options

Top hung system sill sections are available in clear anodised Aluminium or bronze anodised Aluminium. We also offer a Solid timber sill with aluminium bottom guide if a full aluminium sill is not suitable. Our solid timber sill utilises our unique 3d printed drain to remove water from the bottom guide similar to the Aluminium sill sections.

Bottom Rolling sill sections are avialable in clear anodised Aluminium only


Our most popular panel opening configurations include:


Other configurations are available with a maximum of 8 panels folding each way to give 16 panels with a span of 19.2m and an overall frame of 19.3m

Sill Options

The Aluminium sill section is a hybrid sill meaning the external part of the sill is aluminium while the internal section is timber. An example is an Engineered Redwood painted system with a aluminium and hardwood hybrid sill in Sapele, Iroko or Oak.

Our timber sills can be in any hardwood of your choice. 

Brios aluminium sills have a projection of approx 60mm from the frame.

Our timber sills are bespoke made and can have a projection to suit your requirements. Typical projections are 60mm to 90mm.

Threshold Options

The threshold height is dependant on the sill section used. 

Aluminium sills are 38mm high with a 22mm stop to give a threshold of 60mm high.

Timber sills are 45mm high with a 22mm stop to give a threshold of 67mm high.

The stops can be reduced to 18mm to give a lower threshold if required

Addons and Trickle Vents

We offer trickle vents on all our systems. These are usually situated in the head section of the frame and require an internal vent only. The external canopy is omitted due to the vent exiting into the head track 

Oak Bi Folding Door

Glazed and Unglazed Options

Glazed Systems

The glass we supply can be specified to any configuration. Standard door thicknesses allow for a 22mm thick unit which can be increased to 28mm if doors are upgraded to 68mm thick.

As U values are a huge factor in specifying glass options, we are happy to offer any Pilkington glass range from ‘Low e’ K glass to Optitherm to meet the center payne U value you require for your project.

All our glass is safety toughened as standard but we also offer laminated units for added security. These are typically a 6.4mm laminated outer payne with a 4mm toughened inner payne to help keep intruders out.

Unglazed Systems

ALL our bifolds are prepared for a glass thickness 22mm overall as standard. If you are purchasing integral blinds elsewhere to install into our bifolds then please state this when ordering or let us order them for you.

If you are sourcing your own glass then please ensure the glazing meets the required Building Regulations. Door glass must be toughened or laminated safety glass.


Door Delivery Information and Lead Times

Once you place an order we will confirm a production slot and delivery time frame. All our door systems are delivered to you unassembled and require reassembly on site.
Bi Folding Superstore pride ourselves on having a fully transparent ordering routine and this means a smooth process throughout.

Lead times are approx 4 weeks but can be 8 -10 weeks during busy periods and for special orders
