Description

Our Traditional Flush Casement windows deliver outstanding performance and are manufactured bespoke to suit traditional or contemporary properties. 

This window is internally beaded to meet PAS 24 security levels and has applied slim glazing bars to maintain the aesthetics of the original window but with a much higher performance, typically achieving a whole window U value of 1.4 – 1.0 W/m2K and acoustic ratings Rw of 29-38dB depending on the make-up of the glass unit. 

Constructed with slim frame and sash profiles, the Traditional Flush Casement Timber Window uses concealed friction hinges which can be side, top or bottom hung. 

Traditional Flush Casements can be supplied fully finished with a 3-coat spray-applied microporous water-based paint system or can be supplied primed only for a topcoat to be applied on site by others. 

All our Traditional Timber Casements come with a choice of fasteners, stays and restrictors with a wide range of option finishes. 

Features and benefits:

  • With smooth lines, these traditional flush timber casement windows sit beautifully in the frame, and are Secured by Design (SBD) certified.
  • These flush casement timber windows open outwards and can be top or side hung.
  • They can also be supplied fully reversible to enable external glass to be cleaned safely from inside the building: perfect for high-rise developments.
  • Available in four glass options, mounted in hardwood of softwood frames.
  • Double and triple glazing is available.
  • With double gasketing, weather containment is assured; and beading is mounted internally to enhance security.
  • FSC certified.
