The new range has been designed to act as a full replacement for sash windows, allowing building managers to integrate security through design into a property. The range also eliminates the need for secondary glazing or further planning permission.

Claiming to offer the best security performance in the market for sash windows, the windows are made of steel-reinforced hardwood and intruder-proof glazing, which is rated to BS EN 14449. Steel-reinforced box sections with integrated wall fixing points, and steel-reinforced sashes further enhance the security. All windows feature six locking points and high quality brush strips for draught and sound proofing.

To integrate the windows into any design, they are available in three different variants – 6mm single pane laminated glass, anti-bandit 20mm double-glazing, and 30mm triple-glazing. All sashes are of single-pane construction with internal glazing bars, in a variety of sizes. If the appearance of multiple panes is required, stick-on external glazing beads are also available to complete the look.

KSDW plans to get these sash windows tested in 2013 to achieve Secured By Design approval.
