Application

Particularly suitable for use in conservation areas.

Description

A range of purpose made windows, manufactured from W20 steel sections which offers versatility in both size and shape.


Features and benefits:

  • The ability to reflect older styles - and the slim frame members - make this range particularly acceptable for use in conservation areas.
  • Matching doors are available in the Corporate® W20 range to provide a total system solution - hot-dip galvanized and polyester powder coated doors match the slim sightlines of the windows.
  • If not direct fixed, fixing brackets are designed to be bolted to frame and screw fixed to structure.
  • Fixing brackets, screws and bolts, etc. are supplied by Crittall as part of the window frame.
  • The type of bracket will be determined by the manufacturer after receipt of order, in consultation with the main contractor and architect.
  • Glazing up to 16.4 mm thick can be accommodated.
  • Delivered unglazed for site glazing. Crittall can also supply glazing units.
  • The thickness of glazing units will determine the types of gaskets and beads supplied.
