Commercial Window 40mm - Design

The 40mm Commercial Window has been designed to provide a practical solution for low and high rise commercial buildings as well as use in residential projects.

The key objectives of the design were to provide:

  • Strength to accommodate very high and specific wind zone requirements.
  • Flexibility to accommodate commercial or residential installation detailing.
  • Option to integrate with commercial and residential hinged doors.
  • 25mm cover facing.


These objectives are met through key design features in 40mm Commercial windows which include:

  • Use of flanged or chair frames with beaded seismic frame and sill tray option providing flanged, fixed or seismic frame options.
  • Casement and awning sashes (with manual, remote or powered operating gear).
  • Strong and heavy box back mullions for large windows or joinery subject to higher wind zones.
  • Light, medium and heavy duty mullions and transoms to suit low to very high wind pressure zones.
  • Split mullions for continuous walls of windows (horizontal or vertical).
  • Frames which accommodate glazing from 4mm-24mm with a variety of bead options, sloped or square.

The split mullions eliminate the need for bulky coupling when long runs of windows are required whilst meeting the seismic/expansion requirements needed in many situations.


Sizes

Maximum sizes for awning, casement, fixed windows and sashes varies by width, height, wind zone and glazing requirement. Your local Bradnam's branch will be able to advise whether a configuration is possible.

As a guide fixed window panels up to 2.0m height 1.2m wide are recommended with sashes of 1.8m x 1.2m. Other sizes are possible please contact you local Bradnams fabricator for advice.

Note: For compliance with NZS 4211:2008 or NZ Building Code F4 safety from falling, a security stay, safety latch or restrictor must be used for certain sash sizes.

  • A range of 6 mullions and transoms ranging from standard, medium and heavy are available to accommodate style or performance strength required to meet deflection requirements.
