Why choose aluminium bifold doors?

patio folding door
Our aluminium folding sliding doors are strong and durable with slim sightlines and can be specified to open in or out. The Smart Systems Visofold Bi-fold door system uses dedicated aluminium profiles specifically designed for the purpose and has a long pedigree having been used for many years in Europe and lately in the UK as a folding sliding door suitable for both domestic and commercial installations.

Easy to Operate

Our bi-folding doors slide effortlessly using bottom fitted dual rollers running on a dual track and also have the benefit of nylon guide rollers at the top which together with a combination of floating and sliding mullions ensures positive and easy movement of the individual door panels during the fold and slide operation.

High Security Locking Standard

Traffic door handle Our folding doors are fitted with high security locking systems to ensure your peace of mind. For doors without a traffic door operation of the shoot-bolt locking system is only accessible from the inside using the key operated lockable meeting stile twist handles. Doors with a traffic door will have a lever handle operated multi-point hook lock system fitted similar to a normal entrance door. The handle also includes a profile key cylinder deadlock facility which is accessible from both inside and outside enabling a conventional entrance door facility without opening up the complete door.

The locking mechanism and rollers are fully concealed when the door is closed providing an aesthetically pleasing and secure folding door solution.

ENERGY EFFICIENT DOUBLE GLAZING

The solar control benefits of STAYCOOL also provide shelter from direct sunlight in the summer by reflecting 57% of direct heat from the sun and reduce glare by 35%. STAYCOOL is a neutral glass and does not have a coloured tint.
