Allstyle Bi-fold Doors

Smart Aluminium

Offering impressive opening apertures that unite internal and external areas, Allstyle bi-folding doors create unique living and social areas. Suitable for both residential and commercial applications, and ideal in domestic applications as an alternative to sliding doors, or to open up an entire wall as part of a conservatory; the system will make the most of a beautiful view or bring a garden into the home.


Used commercially in a bar, café or restaurant, they can create a glazed screen that allows in the maximum ingress of light in inclement weather, and will also easily glide to open up an entire wall in warmer weather. A choice of opening configurations to suit any application. Choose to fold the sashes internally or externally, place the opening at the side so the sashes all fold one way, at one end, to create a single entrance door for easy access, or in the middle to give the option of a double door.

Low Thresholds – Our bi-folds have the option of either low thresholds for unimpeded, easy access, or rebated thresholds that offer improved weather resistance and are available in a choice of standard or non-standard colours, including dual and a range of textured finishes.


High-Security Locking System – Our folding sliding doors are fitted with the latest high-security locking. On styles supplied with a traffic door, lever handles operate a high-security hook bolt locking system and a profile key cylinder allowing access from both inside and outside. Bi-fold doors supplied without a traffic door do not have external access and can only be opened from the inside by operating the shoot bolt locking system, using the handles fitted to the meeting stiles of the door.


Traffic Door Option – Many styles can be specified with a traffic door which provide a normal day-to-day door leaf, allowing easy access to the garden without opening the whole bi-folding door up, either like a conventional door or French door.



Our range of aluminium bi-fold doors is fully compliant with Doc L of the Building Regulations (Conservation of Fuel and Power).


Allstyle aluminium bi-folding doors are manufactured with a polyamide thermal break, creating a barrier between both the internal and external aluminium sections – reducing heat loss.


Where ordered with glazing, our bi-folding doors can be supplied with double or triple glazed units with a centre pane U-value of 1.2W/m2K and an overall U-value of 1.8W/m2K.


Our bi-folding doors, manufactured from aluminium, are an innovative product and aluminium is, without a doubt, the perfect material for the manufacture of bi-folding doors. Its strength to weight ratio is unparalleled, it won’t expand or contract in extreme temperature conditions, and it is virtually maintenance-free. Also, aluminium can be powder coated to practically any colour, even in a marine-grade coating.


Affordable Aluminium bifold doors are manufactured from slim thermally broken aluminium profiles, which provide strength and security, allowing you to fold and slide the panels back to left or right and open up a wide, unobstructed opening to a patio or garden.

Aluminium bi-folding doors have grown in popularity over the past decade and have become a fundamental feature when designing new-build homes, extensions, or renovation projects. There are many reasons for this rise in demand – they are versatile, save space, increase natural light, and bring your outside inside with a flush floor level. A folding and sliding door enables you to open up to 90% of a wall, transforming any space.


They are a very effective alternative to the traditional aluminium French door or even an aluminium sliding patio door, both typically offering a much lower opening at approximately 40%.
