Difficult to force because of the inherent strength of their frames, steel windows are not liked by burglars. One of the best deterrents to a prospective thief is the traditional ‘cottage’ style steel window, divided into small frames, with interlocked steel glazing bars. Steel Window Association members also offer W40 steel windows that comply with Secured by Design requirements.
Steel Window Association member, Steel Window Fittings Ltd (SWF), manufacture most steel window hardware. SWF has been successfully manufacturing handles, stays, hinges, bolts and openers, as well as safety locks/restrictors and concealed multipoint hardware for metal framed doors and windows, to the commercial and domestic sectors, since 2011; both in the UK and globally.
The strength and security of steel windows and doors is increased through the use of appropriate hardware. When manufacturing new windows, Steel Window Association members provide locking devices, locking handles, concealed bolts and mortice deadlocks. Locking handles are also supplied for existing installations to provide the highest levels of security. To achieve the greatest protection against forced entry, hardware is attached using steel screws threaded into the steel frame.
A concealed multi-point cremone bolt locking system, operated through the frame by a geared handle, offers enhanced resistance to intrusion on new windows in the W40 range. When specified, glazed steel framed doors can be fitted with security mortice deadlocks.
Glass is not easily removed from today’s steel windows. Modern adhesive sealants and metal beads firmly secure the panes and, in vulnerable areas, small pane ‘T’ glazing bars and laminated glass can be employed, making breaking and entering difficult. Even if the pane is broken, locked handles and stays will maintain security.
Effective air movement need not be compromised by good security. A two point locking handle will allow the option of leaving the window cracked open or trickle ventilation can be provided through the head of the window.
