The W40 steel profile offers the same design aesthetic as the W20 predecessor but with some additional features.

The W40 Steel Profile Design Plus London

Introduced in the 1990s, The W40 steel profile series compliments the slim, classic look of the W20 window with an increased profile depth.

Slim sight lines, large panes, thermally efficient and beautiful aesthetics.

Although the site lines are largely unchanged, the greater depth allows for additional benefits to the steel windows:

  • Increased thermal efficiency
  • Larger double and triple glazed units (up to 26mm in thickness)
  • Improved acoustic performance
  • Increased strength
  • Concealed Multi-point locking system

As a result of the deeper sections, W40 Steel Doors are well suited to external applications as well as in commercial use. The W40 doors and windows comply with Part L of current building requirements for heat loss.

In addition, the thicker sections allow for larger windows and doors to be manufactured. When sturdy and robust windows and doors are required the W40 steel range will not disappoint.
