Typical sunglasses are darkened for protection against bright light or glare; some specialized glasses are clear in dark or indoor conditions, but turn into sunglasses when in bright light. Most sunglasses do not have corrective power in the lenses; however, special prescription sunglasses can be ordered. Specialized glasses may be used for viewing specific visual information (such as stereoscopy) or 3D glasses for viewing three-dimensional movies. Sometimes glasses with no corrective power in the lenses are worn simply for aesthetic or fashion purposes. Even with glasses used for vision correction, a wide range of designs are available for fashion purposes, using plastic, wire, and other materials. Fabricated and installed by Dortech Architectural Systems Ltd, Senior’s patented PURe® aluminium folding sliding doors feature as part of a stunning extension to Ms Stephen’s home. Offering slim sightlines that maximise views of the property’s pretty garden, the narrow yet robust aluminium frames of the PURe® doors have been powder-coated to provide an attractive brown finish that further complements and connects with the outdoor space. The UK glass industry is pursuing an active programme on energy efficiency and decarbonisation. But building the business case to secure funds remains a barrier. Capital costs can be very high and paybacks periods are often in excess of two years; traditional loans are usually unattractive for this work. Awarded a UK patent, Senior’s PURe® range of energy-efficient aluminium windows and doors is the first on the UK market to benefit from an enhanced thermal barrier manufactured from expanded polyurethane foam (PUR). Traditionally used in cladding and insulation products, the innovative use of PUR as a thermal barrier in windows and doors gives the PURe ® range the potential to achieve U-values as low as 0.71W/m2 K when calculated as a commercial CEN standard window and 0.93W/m2 K when calculated as a CEN standard door.
