Adapting bulky wide uPVC steel reinforced profiles that were originally designed for traditional hinged external doors meant glass sight lines were considerably reduced and the doors used ugly face fixed hinges and exposed gearing which also sometimes posed a security hazard. However, some manufacturers have started to introduce the next generation of uPVC folding doors using slimmer profiles and concealed gearing that compare favourably with those of timber and aluminium. Heavy steel profile reinforcement is starting to be replaced by lighter yet stronger recycled composite material that is also much more energy efficient.
The huge growth in demand for folding sliding doors over the last two or three years has led to a rapid increase in the choice of door systems available for the consumer. Also referred to as bi fold doors, bi folding doors, multi fold doors and concertina doors they are best known as folding sliding doors because of the opening action itself. This type of door can provide unobstructed openings of up to 6 metres and sometime more as the panels simply fold, slide and stack neatly to one side or both sides of the aperture. Folding sliding doors are an ideal replacement for existing French or sliding patio doors where they can literally transform the existing opening and open up the room to the outside. This type of bi folding door is now becoming the most sought after door style for new build and home extensions whilst also proving a popular upgrade choice for homeowners adding a conservatory to their property due to their ability to seamlessly merge the new conservatory with the garden effectively bringing the outside inside.
Aluminum slide doors uses thermally broken, strong and durable aluminum for this purpose. Such doors have been used in hotels and restaurants since many years. They are the older forms of sliding doors that have been used in both commercial and domestic areas. The system designed for the purpose uses top that has guide rollers and all the weight is put to the bottom. This way smooth operation of opening and closing of door is achieved. It is still one of the most demanded materials for sliding doors as they dont require much maintenance. Plastic or PVC is another popular choice in sliding doors since they are the latest ones. The cost of doors with plastic is the least as compared to other materials. They are the best choice when there is demand of affordable and long lasting doors. At times you will have to compromise with the quality of plastic if you want a good design.
TIMBER You can choose from a number of engineered timber folding sliding doors including softwood or hardwoods such as Meranti and European Oak. Timber is normally engineered or laminated to ensure it is structurally resistant to warping or twisting and doors are normally available with either a factory applied translucent stain or RAL colour paint finish. As timber is a natural insulator timber folding sliding doors offer the most energy efficient solution when combined with high performance double glazing offering U values as low as 1.4. Timber folding doors usually provide slim sight lines as the individual door panels are normally hinged off each other without the use of additional mullions between each panel and therefore maximising visible glass areas.
