54mm ThicknessAvailable sizes: 6', 8', 10', 12', 14' or 16'The folding/sliding doors and frames have premium grade Schlegel® weather seals and patented high performance stainless steel folding/sliding hardware with matching pvd chrome door handles. Every door and frame is "double sealed", front and back, to prevent draughts and water ingress.The bottom of the frame of the standard doorsets has a unique timber/aluminium combination cill design, incorporating an aluminium sub-cill for optimum drainage, and specifically designed for use in external wall installations.With the timber cill incorporated, the doorsets have been weather tested to BS6375 Part 1.The doorsets feature 24mm thick Pilkington K Low E Glass Double Glazed Units, which is tempered to the latest tempering standards - BS EN 12600 and BS EN 12150.“Tempered” means that it is up to five times stronger than standard glass and, for safety, if smashed, exhibits similar properties to a car windscreen, breaking into small pieces rather than highly dangerous shards.The doors comply with Building Regulations (Part L) and have a thermal rating 1.9 W/m2K. This helps to keep your home warmer in the winter and cooler in the summer and also helps lower the carbon emissions from the property. All doors and frame sets are made from engineered timber, including a laminated hardwood core, which provides added stability and reduces twisting, bowing, warping and splitting.Each access door has a robust, 3-point security locking system, which is engaged by lifting the handle and locked with a turn of the key in the Euro cylinder. Additionally the doorsets incorporate internal drop bolts in between each folding “leaf”, which slide up and down into the timber of the frame. The bottom bolt always locks for increased security.All sets are top hung, so unlike more temperamental and troublesome bottom roller systems, they won’t jam or stick when slightly clogged with everyday dirt and debris. Whilst “top hung” is mechanically the most efficient method, it means all the weight hangs from the top, so it is imperative that an adequate lintel is over the brickwork opening and that the VUFOLD frame head is securely fixed into the lintel.The majority of components are pre-machined for ease of assembly.Frame fixings, special lintel fixings which don’t require rawl plugs, special drill bits and screw driver bits are also included. ( NB - designed for a standard fitting. Some properties, such as timber-framed houses, may need different fixings.) Comprehensive installation instructions are also included.
