Acoustic ratings of Rw 29–31dB and an anticipated life expectancy of 60 years with regular maintenance complete the specification.

Operating on a cord, weight and pulley system – with a spring balance option also available – these windows are available fully finished or primed, with a wide choice of ironmongery finishes.

Manufactured in engineered laminated pine, hardwood or Accoya from FSC or PEFC certified sustainable sources, these box sash windows achieve air permeability of Class 3, water tightness of Class 5A and wind resistance of Class 4C.
