NFRC certified.- U-values as low as .20 One of the best energy performances in the steel windows industry, with values rivaling high-performance wood windows.- Factory glazing means products will ship with NFRS label attached to glass.

  • Metalizing process ensures that the window will be free from rust and helps to increase the window's lifespan.

  • Polyester powder coating means that a steel window will not need to be painted for at least twenty years. We have our exclusive finish colors selection. A wide range of colors are also available and can be specified using the RAL color chart system.

  • Opening windows can be hinged on the side or the top and come complete with ironmongery that can be sympathetic to the original or with a more modern look. They have a double weather seal and so exceed PAS23 requirements.

  • Glazing decoration can be specified so that the window retains an existing leaded, Georgian or Modern glazing appearance. The glass units are made up of soft coat glass which helps retain the heat in a home, low ion glass which draws the suns rays through the glass in the winter months, Krypton gas helps increase thermal insulation as well as the added benefit of increased sound insulation and a warm edge spacer also helps increase thermal insulation.

  • Doors are manufactured from either W20 or W40 steel profiles and complement the steel window in profile and style. Single and double (French) doors are available and can be manufactured to very large dimensions.

  • Doors are available with traditional mid rails and kicking panels or with large full height glass panes. Locking mechanisms can be traditional mortise locks with lever/lever handles and shoot bolts or concealed multi locking with an internal handle.
