Enfield Garage Door Locks – The massive increase in demand for folding sliding doors over the previous two or three years has led to a rapid increase in the option of door systems available for your consumer. Also known as bi fold doors, bi folding doors, multi fold doors and concertina doors they’re best known as folding sliding doors because of the opening activity itself. This sort of door might offer unobstructed openings of around 6 metres and more as the panels only fold, slide and stack neatly to one side or both sides of the aperture.
Folding sliding doors are an ideal substitute for existing sliding or French patio doors in which they could literally transform the existing opening and open the space to the outside. This sort of bi folding door is now becoming the most sought after door style for new build and house extensions whilst also proving a popular upgrade option for homeowners including a conservatory for their property due to their ability to merge the new conservatory with all the garden effectively bringing the outside inside.
Even though the original concept of a folding sliding door dates back over 100 years in which they were frequently used for closing off little storage areas now’s folding sliding doors are designed to be high performance energy efficient terrace doors utilizing the latest advanced insulation features in both door and glazing construction.
Folding sliding doors not only allow wider unobstructed apertures but also the increased glass area allows huge flows of natural light to enter the house from the outside which throughout the colder months will offer efficient use of solar gain to minimise heating expenses. Doors are available in a selection of materials including wood, aluminium and PVC-u along with a selection of colors and finishes that can enhance any house.
You can choose from many of engineered wood folding sliding doors including softwood or hardwoods such as Meranti and European Oak. Timber is usually engineered or laminated to ensure it’s structurally resistant to warping or twisting and doorways are normally available with a factory applied translucent blot or RAL colour paint finish.
As wood is a natural insulator wood folding sliding doors offer you the most energy efficient solution when combined with high performance double glazing offering U values as low as 1.4.
Timber folding doors typically offer slight sight lines since the person door panels are normally hinged off each other without the use of further mullions between every panel and so maximising visible glass locations.
Timber is a natural renewable substance that’s very energy efficient but will require routine maintenance over the life period of this door to keep their stain or paint finish.
Aluminium folding sliding doors are normally manufactured from durable, powerful thermally broken aluminium profiles that have specifically been created for the purpose. These systems are in use for several years in both domestic and industrial installations such as restaurants and resorts.
Most systems utilise bottom rolling gear so all the weight is carried in the bottom with guide rollers at the very top and panels are often connected to slipping and floating mullions which help ensure the door operates smoothly and effortlessly.
Aluminum is a favorite option for this type of folding door since it’s virtually maintenance free, hard wearing and good looking. Aluminum folding sliding doors are available in over 200 different RAL paint finishes which can usually be specified in your choice of matt, silk or gloss finish. It is also possible to specify dual colours with another colour internally and externally.
Also known as vinyl or PVC-u fold sliding doors this type of door is comparatively new on the market place when compared to aluminum or wood. Owing to the comparative low cost uPVC door producers have quickly adapted their existing uPVC door profiles to make bi folding doors in response to an increasingly expanding market that demanded a more affordable folding door method. UPVC folding sliding doors could be substantially less costly than their aluminum or wood counterparts but there’s frequently a trade-off in design elements that may sometimes compromise the quality of the product.
Adapting bulky wide uPVC steel reinforced profiles that were initially made for traditional hinged external doors meant glass sight lines were substantially reduced and the doorways utilized ugly face fixed hinges and vulnerable gearing which also sometimes posed a safety threat.
However, some manufacturers have started to present another generation of uPVC folding doors with thinner profiles and concealed gearing that compare favourably with those of wood and aluminium. Heavy steel profile reinforcement is beginning to be replaced by lighter yet stronger recycled composite material that’s also more energy efficient.
