Synerjy UPVC

Synerjy is a 70mm multi-chambered ovolo UPVC system developed as a new build and replacement solution where a more traditional looking window and door system is specified. Synerjy combines the sculptured features of traditional window beading with the modern benefits of quality, low maintenance UPVC. The elegant sculptured edge is carried consistently across window, door and beading detail and a range of heavy duty couplings and expansion mullions are available for structural glazing if you’re looking for an ovolo system for larger commercial projects.

Synerjy features:

  • Three outer frame sizes including a chamfered option
  • Low sightline gaskets
  • Combined bubble and flipper gasket for enhanced weather protection
  • Full depth Eurogroove
  • Decorative options including sash horns and Georgian bars
  • Identical bead and up stand detailing for equal sightlines
  • Choice of woodgrain finishes and colours

The flexibility of the Synerjy window system enables various window specifications to be used to achieve a given target U-Value to optimise the best value for money for any given project, up to and including Passivhaus standards.
