Exceptional Thermal EfficiencyTraditional sash windows are notorious for being drafty and cold. Modern uPVC sash windows utilize multi-chambered profiles that trap air, acting as an insulating barrier. When coupled with high-performance double or triple glazing, these windows can attain an "A" energy ranking, significantly decreasing heating expenses and carbon footprints.2. Improved SecuritySecurity was a major worry about older sash styles, which often featured easy locks. Modern uPVC windows are equipped with reinforced frames and advanced multi-point locking systems. Toughened glass or laminated safety glass can also be integrated to offer an additional layer of security versus burglars.3.
