Description

The 58BW ST HI Steel Replacement Window System provides the look of steel with the benefits of aluminium. Designed to replace and complement existing steel windows, the range has been specifically developed for use on listed buildings, warehouses and similar buildings, where steel windows have always traditionally been fitted.


It is available in a wide range of styles including top hung, side hung, fixed, light and French casement light and French casement, the system cleverly replicates the narrow sight lines associated with steel windows whilst providing superior performance and security. The system also includes hardware that is sympathetic to traditional steel window designs.


Features and benefits:

  • Slim sightlines to match existing steel windows.
  • Internally and externally beaded for ease of site glazing on high-rise applications.
  • Distinctive polyamide thermal break design to improve performance.
  • Integrated deep head profiles for ease of trickle ventilation.
  • Accommodates standard hardware including friction stays and shoot bolt locking.
  • Accommodates up to 32 mm glazing units for thermal and acoustic performance.
  • Casement clips available for easy fit and removal of dummy vents.
  • Dedicated fixing straps for ease of installation.
  • Four different sash profiles to achieve design and planning permission requirements.
  • Available in single or dual colour polyester powder coating, texture and anodized finishes.
