Heavy Duty Exterior Door – The massive growth in demand for folding sliding doors within the previous a few years has caused a rapid increase in the choice of door systems available for your consumer.

Folding sliding doors are an perfect replacement for existing French or sliding patio doors where they can literally alter the existing opening and open the space to the exterior. This type of bi folding door is now becoming the most sought after door style for new construct and home extensions whilst also demonstrating a popular upgrade choice for homeowners adding a conservatory to their property on account of their capacity to seamlessly combine the brand new conservatory with the backyard efficiently bringing the outdoors inside.

Folding sliding doors not only enable wider manicured apertures but also the higher glass area allows huge flows of natural light to enter the home from the exterior which throughout the colder months will provide efficient utilization of solar gain to minimise heating costs. Doors are available in a choice of materials including timber, aluminium and PVC-u along with a choice of colors and finishes which can enhance any home.


You can choose from a number of engineered timber folding sliding doors including softwood or hardwoods like Meranti and European Oak. Timber is usually engineered or laminated to ensure it is structurally resistant to warping or twisting and doorways are typically available with a factory applied translucent blot or RAL colour paint finish.

As timber is a natural insulator timber folding sliding doors offer you the most energy efficient solution when combined with high performance double glazing supplying U values as low as 1.4.

Timber folding doors usually provide slim sight lines since the person door panels are typically hinged off each other with no use of further mullions between every panel and so maximising visible glass areas.

Timber is a natural sustainable material that is very energy efficient but may require regular maintenance within the life period of the door to maintain their stain or paint finish.


Aluminium folding sliding doors are typically manufactured from durable, powerful thermally broken aluminium profiles which have specifically been designed for the purpose.

Most systems use bottom rolling equipment so all the weight is carried at the base with manual rollers at the very top and panels are usually connected to sliding and floating mullions which help to ensure the door operates smoothly and effortlessly.

Aluminum is a popular choice for this kind of folding door since it is virtually maintenance free, hard wearing and great looking. Aluminum folding sliding doors are available in over 200 different RAL paint finishes which can normally be given in your choice of matt, silk or gloss finish. It is also possible to specify double colours with another colour internally and externally.


Also known as vinyl or PVC-u folding sliding doors this kind of door is comparatively fresh on the market place compared to aluminum or timber. Due to its relative low cost uPVC door producers have quickly adapted their current uPVC door profiles to make bi folding doors in reaction to an increasingly expanding market that demanded a more affordable folding door system. UPVC folding sliding doors can be substantially cheaper than their aluminum or timber counterparts but there’s frequently a trade-off in layout elements that may sometimes compromise the quality of the item.

Adapting bulky wide uPVC steel reinforced profiles which were initially made for traditional hinged exterior doors supposed glass sight lines were substantially reduced and the doorways used awful face fixed hinges and vulnerable gearing which also occasionally posed a security hazard.

However, some manufacturers have begun to present the next generation of uPVC folding doors using slimmer profiles and concealed gearing which compare favourably with those of timber and aluminium. Heavy steel profile reinforcement is starting to be replaced with lighter yet stronger recycled composite material that is also much more energy efficient.
