Description

Energy efficient windows which make use of symmetrical multi-chambered PVC-U profiles, reducing unnecessary steel reinforcement. Flush sash windows are beaded internally or externally and offer a number of features and benefits in a range of styles. The slim frames increase the flow of natural light as well as creating an enhanced field of view - and with the sash fitting flush against the outer frame, replicate the appearance of pre-1932 timber windows.


Available in EnergyPlus six-chamber profile, offering Windows Energy Ratings up to A++ depending on glazing options, the range is available in a wide choice of colours and finishes from stock, with special colours available on longer lead times.


Features and benefits:

  • Patented co-ex bubble gasket.
  • Thermally efficient.
  • 100% lead-free PVC-U.
  • Easy to install.
  • Ten year profile guarantee.
  • Slim sightlines.
  • Replicates a pre-1932 timber window.
