DOORS&WINDOWS New mainframe boasts 8-chambers Sheerframe 8000, the very latest suite of lead-free 70mm window system profiles from the pioneers of thermoplastic extrusion, now offers a new 8-chambered mainframe option designed to provide an array of specification benefits. »»Available in popular contour styling, the new 8-chambered mainframe is slim in appearance with a large face of 52mm to complement the 60mm intermediate frame and the 70 x 70mm large frame. When used in combination with a 5-chambered sash fitted with an expanded PVC foam Thermlock frame reinforcement and 44mm Argon gas-filled triple glazing, the 8-chambered mainframe window specification will comfortably deliver an A+ WER “zero carbon” thermal performance with an impressive U-value of just 0.8 W/m2K. With a 14mm wide rebate upstand and a 56mm glazing area, the Sheerframe 8000 system offers a future proof choice of 28mm, 36mm, and 44mm double and triple glazing along with a glass bonding platform built in from the start. “The 8-chambered mainframe gives greater structural strength and enables fabrication of largespan windows requiring no reinforcement in most cases,” comments David Strang, Sheerframe’s Group Key Account Director, “and this new Sheerframe 8000 profile specification is also a winner in terms of reduced cost and superior thermal performance.” C L E A RV I E W-U K .
