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. “None of the homeowners featured on the show know they’ve been chosen to receive a home makeover – it’s a surprise, so I can’t say any more about the episode we’re involved in at the moment. You’ll have to tune in and see it for yourself!” The new architecture also means the pages on the content rich site now load in milliseconds, ensuring that potential customers visiting the site are engaged for long enough to register their interest. 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. Owing to the property’s location in heart of the Yorkshire Dales, it was also vital that the new windows and patio doors offered superior thermal efficiency and acoustic performance as well as ease of operation and an attractive appearance. Friends and colleagues gathered to applaud worthy winners across seven categories – and recognise the creativity and dedication which underpin the whole sector’s contribution to the economy, to society and to customers, staff and stakeholders. British Glass is organising a one-day seminar on funding for decarbonisation and energy efficiency work on Thursday 2 November (north of England, venue TBC) – which will be attended by British Glass members’ and non-members.
