PVCU Window to meet Level 6

PVCU Window to meet Level 6
LB Plastics Ltd have produced a Pvcu window system that meets with Zero Carbon standards and claim to be the Uks first company to achieve a code for sustainable homes level 6 compliant window.
The window - Sheerframe HED (homogenous energy dynamics) is fully reinforced with Thermlock FP metal-free structural PVC foam which is 100% recycled, the lead free pvc possesses the same strength characteristics as an equivalent metal reinforcement and is both environmentally friendly and sustainable

Steel and aluminium reinforcement are known to affect the overall thermal performance of pvcu windows but . Sheerframe feature Thermlock®, developed by wrapping the metal in a specialist insulating thermoplastic compound.
The Sheerframe HED window manufactured in the UK has a 0.8 W/m2K U-value, is triple glazed with a solar factor of of 0.6 W/m2K and are certified to BS 7950 / BS 6375 with BBA approvals
Sheerframe windows feature four or five chamber profiles, increasing the honeycomb effect of the frame to reduce thermal conductivity

Recycling PVCU windows
The Vinyl 2010 Voluntary Charter which stretches’ across Europe sets outs that the production and disposal of PVC is carried out with total environmental responsibility.
The sheerframe window with a lifespan of thirty five years can be fully recycled when the frames are eventually replaced which makes this window fully sustainable

Scottish fabricator of the Sheerfame profile - CMS Enviro Systems Ltd have developed the capacity to recycle PVC and Timber windows/doors and. When the old frames are removed from a property they are broken down and recycled into
bi-products.. 100% of these bi products are then recycled to create a number of products including new windows.

What Is PVC
Polyvinyl chloride (PVC) is a thermoplastic material used in a everyday applications and products. The key raw materials used in the process comes from oil & salt . When the electrolysis of salt water takes place it produces chlorine, which when combined with ethylene, extracted from oil, produces vinyl chloride monomer (VCM). From here molecules of VCM are polymerised and a PVC resin is formed when additives are incorporated we end up with a customised PVC compound.
When PVC is plasticised it becomes flexible and is used in a number of applications ,flooring ,food packaging, medical products etc. rigid “PVC known as PVC-U”, the U meaning unplasticised is used throughout the building industry and the manufacture of window frames.
