Glasses are typically used for vision correction, such as with reading glasses and glasses used for nearsightedness. Safety glasses provide eye protection against flying debris for construction workers or lab technicians; these glasses may have protection for the sides of the eyes as well as in the lenses. Some types of safety glasses are used to protect against visible and near-visible light or radiation. Glasses are worn for eye protection in some sports, such as squash. Glasses wearers may use a strap to prevent the glasses from falling off during movement or sports. Wearers of glasses that are used only part of the time may have the glasses attached to a cord that goes around their neck, to prevent the loss of the glasses. 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. 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. This beautiful bespoke bottle was designed by M&E Design. It perfectly demonstrates how glass can be used as a vessel for ambition, style, and sophistication. The bottle was created with none of the usual visual cues of a standard whiskey bottle. Instead, it was crafted to celebrate the liquid inside and the process behind its creation. The design takes its cues from laboratory glassware found in the micro-distillery and the paneling of a whiskey cask. It has been shaped to refract and bounce light. The side panel embossing produces a Kaleidoscope of patterns within the body of the bottle, bringing Method and Madness together. Offering exceptional thermal efficiency, build quality, and desirable minimalist aesthetics, Üni_Slide can achieve frame sightlines as slim as 20mm, and a slim central interlock, while being able to support sliding panels of up to 3m high and 2.2m wide. The product can be assembled in a limitless run of units, with each panel capable of holding up to 320kg of glass. Martin Nettleton adds: “We invested in the campaign to target those larger installation and distribution companies increasingly dissatisfied with the big fabricators who are starting to compete with them by setting up their own networks of trade counters and distribution outlets.
