You’ll have to tune in and see it for yourself!” Commenting on the recent renovations, Ms Stephens said: “I am absolutely delighted with the work that has been carried out and Dortech’s customer service and professional installation has been second to none. The popular programme, which has been running since 2011, and regularly draws audiences in excess of 4m, sees a team of home improvement experts led by Alan Titchmarsh transform properties for deserving families in difficult circumstances. To complete the stylish extension, a number of the property’s existing hardwood windows have also been sympathetically replaced. Tasked with identifying a system that could match the visual appeal of the original wooden frames whilst offering improved quality, usability and security, the Dortech team took the innovative step of suggesting a change to aluminium. After reviewing alternative products on the market, Senior’s high quality PURe® aluminium windows were found to significantly outperform cheaper aluminium systems and offer the perfect solution in terms of both performance and aesthetics. Sunglasses allow better vision in bright daylight, and may protect one's eyes against damage from high levels of ultraviolet light. 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.
