Architectural aluminium systems supplier Kawneer widens its window range
Architectural aluminium systems supplier Kawneer has widened its AA®540 window range with side-hung and bottom-hung variants of its tilturn system. The new AA®543 side-hung and bottom-hung open-in variants join the original AA®543 tilturn (tilt for ventilation and turn for cleaning) and an AA®541 casement and AA®542 pivot window. The company says the windows have U-values down to 1.5W/m2K and full compliance with Document L, while optional trickle ventilation also helps meet the requirements of Document F.
