NEW MAINFRAME BOASTS 8-CHAMBERS
17th February 2015

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 large-span 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.”
