Smart Visofold 2 Pane Bi-Fold Door In Grey (Matt) - (1600mm x 2400mm)

Yes - all of our bi-folding doors meet the new UK building regulations.

If your opening is bigger than the maximum size we can manufacture a bi-fold, we would advise a sliding patio door as a more suitable choice, as these can be made to larger sizes.

A bi-folding door is a large, heavy item with a lot of moving parts, and we recommend they are fitted by a qualified tradesman. Please consult our installation guides for more information.

If installed correctly, an aluminium bi-folding door will require little to no maintenance. Almost all of the issues reported with bi-folds are due to improper installation, so please exercise caution!

You can choose to have the doors delivered fully assembled or in ‘flat pack’. Flat pack orders will have the door sashes delivered separately and the frame delivered in four sections to make up on-site, ideal for larger doors or homes with limited access. Bi-folds over a certain size will automatically be delivered flat pack for ease of transport. Please contact the office for exact details before ordering if more information is required.

Yes, bi-folds are very secure due to their multipoint locking systems. If your door is in a vulnerable area or if you are concerned, you can upgrade to document Q specification. This improves aspects of the door, including laminated glass, which does not smash like normal glass and remains in place even if attacked, similar to a car windscreen.

Yes, we can offer marine-grade upgrades for customers who live within 10 miles of the coast.

Deciding which threshold and sill combination you have on your bi-folding door is perhaps the most important decision. If the wrong threshold is selected, you could have issues with floor levels and door opening clearance. There are various thresholds to choose from, and we recommend consulting the help icon for a detailed explanation of each.

Many customers want to achieve a flush effect, where the transition from the internal to the external is seamless with the doors open. This should be discussed with your builder, as it is ultimately the floor levels that create the flush effect, not the threshold.

It is also important to consider the location of the door. If your door is prone to extreme weather or is in an exposed location, a higher threshold may be more suitable to provide better weather protection.

You will need to work with your architect and planning officer to clarify if trickle vents are necessary. There are many aspects of a build that can affect airflow (air bricks, existing doors, extractor fans, etc.), so it is impossible for us to determine this.

Planning permission is not typically required for replacement windows or doors, providing you are not making any alterations to the original aperture.

For windows going into a new build or extension, planning permission will depend on the size and nature of the build itself. Check with your local council or building authority at the planning stage.

For refurbishment projects in a property you own, you will not need building control or authority sign-off, provided you are replacing the current doors with an improved or like-for-like product.

For new builds and extensions, the products will need building regulations consent and must meet UK building regulations. Accreditations such as document Q, PAS24, and Police Approved may not be essential, but check with your architect or authority.

If larger glass areas and uninterrupted views are your main concern, a sliding door may be a better choice. Sliding doors can be up to 2.5 metres wide per door, compared to a bi-fold where the maximum is 1200mm. However, sliding doors will always have at least one fixed door, so you cannot open the entire aperture as you can with a bi-fold.

We only use industry-leading brands for our products, especially important for bi-folds as they can vary in quality. We proudly display every brand we supply, and any research into these brands will confirm their quality.

Lesser quality bi-folds can be problematic due to their moving parts. Lesser quality bi-folds often require constant adjustment, which can become costly. Be wary of companies that do not disclose the manufacturer they use.

Double glazed: The standard option with two sheets of 4mm glass and a 20mm thermal spacer. Suitable for most applications and the most cost-effective.

Triple glazed: Adds an extra sheet of 4mm glass, improving energy rating and noise reduction. More expensive and heavier than standard glass.

Laminated: High-security glass that holds together when shattered. Suitable for larger panes or in vulnerable areas where security is a concern.

Integral blinds: Magnetic integral blinds inside the glass. Suitable for customers who want privacy without retrofitting blinds or curtains.

Stock colours are Anthracite Grey, Black, and White. We can also offer any colour from the RAL colour chart. To quote for a bespoke RAL colour, please use our online door designer.

In our experience, uPVC bi-folding doors tend to have more maintenance issues. Due to their size and moving parts, bi-folding doors lend themselves better to stronger materials like aluminium. uPVC bi-folds are more prone to ‘dropping’ and need more adjustments, making them less reliable than aluminium doors.

Yes, you can have a traffic door that acts independently from the other doors. This will be the master door on your design, so for example, if the doors slide right, the traffic door will be on the far left.

On 3, 5, and 7 pane designs, the lead door acts as a traffic door. For 2, 4, or 6 pane designs, make sure the door is hinged at the wall side for it to act as a traffic door.

Bi-folding doors (also known as ‘fold and slide’ doors) consist of multiple door leaves (usually between 2 and 7) that fold back on themselves to create a full opening. The doors can slide one way or both ways and fold back onto each other. They run on a track, and magnets hold the doors together for easy folding.

Bi-folding doors are popular because they allow large openings to the outside, making them a stylish and secure product.

2 pane bi-folding doors remain popular due to their stylish and functional nature, allowing full access to your home. Many building companies still specify 2 pane bi-fold doors on new builds, showing their continued popularity.

The minimum width for a 2 pane bi-fold door is typically 700mm per door (1400mm overall). Although smaller sizes are possible, most customers opt for wider doors, such as 2 metres, for better views through the glass.

No, 2 pane bi-fold doors are very secure. Our aluminium doors come with insurance-approved locking systems and 3-star cylinders, resistant to drilling, picking, or lock-bumping. Laminated security glass can also be added, which will not shatter under attack and is required on new builds to meet 2022 security regulations.

A two-man team can fit 2 pane bi-fold doors in a few hours if the opening is prepared. Removing an older door may extend the installation time, but most of our 2 pane bi-fold doors are installed in new openings, such as extensions.

Good quality aluminium 2 pane bi-fold doors should last a long time. Our product comes with a 10-year guarantee and a 5-year glass guarantee. With proper maintenance, such as regular cleaning and lubricating of moving parts, aluminium doors can last 25 years or more without peeling, bowing, or discolouration.
