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. “We are a trade specialist so all retail enquiries and enquiries from smaller independent installers are handled by our customers, which means they are sharing directly in the success of our campaign.” Founded in 2006, Fenster is one of the West Country’s leading aluminium suppliers. In addition to offering the full range of products from Smarts, the company also manufactures Üni_Slide, an ultra-slim aluminium sliding door, equally suited to commercial and residential applications. 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.
