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.
These are not only for places where you need wider place but they are also perfect for places where you need more sun light and fresh area. They give wider space for entry of light and air. The glass used in new innovative slide doors can help in reducing the heating losses as they provide efficient solar gain. When you go to buy these doors then you have ample number of choices in the material and color. There are materials like timber, PVC, aluminum etc.Timber has been used largely with both hardwood and softwood in places where one wants the structure to be resistant against twisting or warping. You find these sliding doors with RAL paint or translucent strain finish. These are very good insulators and therefore efficient energy solution as timber is well known for being a good natural insulator. Good care is taken to maximize the area of glass and reduce the area of panel and framing.
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.
Let us look in to the two main types of doors available today. Top hung Sliding Doors This is the most commonly used type of sliding doors. They are used in commercial places and homes as well. Two trolley hangers are used to hang the door at the top. The hangers take all the weight of the door, which makes the door slide easily without any problems. Track stoppers are fixed on the concealed tracks at both ends. They are responsible to hold the doors at both ends on the track. This type has the maximum weight limit depending on the trolley hangers used. This is the reason most suppliers provide door weights. In simple words, the size of the door matters when using top hung doors.
