Sapa ¾«¶«Ó°ÊÓ Systems has developed the Crown Window System to help specifiers meet the higher levels of the Code for Sustainable Homes
The thermally broken aluminium casement windows have slim frame sightlines - 35mm for fixed lights and 59mm for an opening light plus the outer frame.
The windows can achieve a window energy rating of A and a U-value of 1.6W/m2K with conventional double-glazed sealed units.
