Visofold 1000-Slim Aluminium Bifold Doors

Visofold 1000-Slim Aluminium Bifold Doors

Aluminium folding doors with slim sightlines

FD2U aluminium bifold doors are manufactured from slim thermally broken profiles to ensure maximum glass widths can be acheived using the minimum number of panels.  There are no additional mullions required between the panels that broaden the sight lines so when panels are folding sliding in the same direction the width of the aluminium from edge of glass to edge of glass ranges from 122mm down to a very slim 94mm depending on model selected.

The new Cortizo Bifold-Plus door has a sightline of only 110mm and an overall 0.8 u-value when specifying the triple glazed option.

Luxury aluminium folding doors


Our ranges of aluminium folding doors are designed by two of the UK's leading architectural aluminium system suppliers Smart Systems and Cortizo.  The Smart and Cortizo ranges of bifolding doors have been available in the UK and Europe for a number of years offering both domestic and commercial folding door applications.

Aluminium doors are particularly renown for their ease of operation and reliability in service and our doors also benefit from a stainless steel roller system at the bottom with the panel tops also guided by rollers for smooth running and easy operation. There are no heavy-weight lintels required as the doors are bottom rolling and not hung from the top.

Individual door panels can be up to 1.2 metres wide x 3.0 metres high* to provide wide glass apertures using minimum aluminium profiles which allows natural light to flood into the room.

*Cortizo Bifold-Plus only.  Visofold 1000 Slim maximum panel sizes are 1200mm wide x 2500mm high with Visofold 6000 range maximum panel sizes of 1000mm wide x 2200mm high.

Garden room bifold doors

Garden room bifold doors

Our aluminium bifold doors are the perfect solution for garden rooms as not only do they provide a glass frontage to the room but all our doors are bottom rolling with all the weight of the door on the bottom.  

We also offer a range of standard size doors which are competitively priced and allow you to construct the opening to suit the door.

Standard Size Bifold Doors
Floating corner post

Floating corner post

This corner set has a fully weathered flush track system and has been designed with a moveable corner post that slides open with the main traffic door set eliminating the need for an external fixed corner post.  The corner post shown in this photo is actually on the inside. 

With the appropriate steelwork in place this system also creates a true cornerless bifold door arrangement.

As featured on Channel 4 TV's 'Double your house for half the money'

We supplied and installed this anthracite grey 3 panel aluminium bifold door for an edition of this popular home improvement program presented by Sara Beeney. The door was installed into a basement in a terraced property in Clapham, South London to create extra living space and provide the main source of natural light into the room.

Low Threshold Option

Low Threshold Option

The Cortizo Bifold-Plus offers a fully weathered flush bottom track that provides seamless floor levels inside and out as you will see from the image opposite.  Combined with an adequate drainage system the flush track is the perfect solution for eliminating any possible trip hazard.

Offering full protection against the weather this option provides a solution for many who do not want a rebated threshold that usually requires a step down from the internal floor level and can mean up to 50mm high of step-over aluminium upstand above your internal finished floor level.

There is also a non-weathered low threshold available on both the Visofold and Cortizo door that allows you to create flush floor levels between two internal living spaces such as between the main house and conservatory by sinking the threshold into the floor merging the two floor areas into one.

Aluminium folding doors are ideal for use as conservatory doors and are often requested by customers who feel aluminium provides a stronger durable door especially when wider openings are required. When fitted in conjunction with a steel portal frame doors up to 6 metres or wider can be fitted to open-up the complete front of a conservatory or as shown here two bifold doors can open up the corner of the structure with stunning effect.
