same principal as armoured laminate glass , just cheaper....good find...may go belt and braces and get this fitted to....worked out on average for my 2 windows and 2 doors that are being fitted an extra £100 per unit to upgrade to armoured laminated glass and tougher frames with all round shootbolts(well worthwhile i think) where this really comes into its own is retro fitting to already in place windows and doors.
Nothing is fool proof for a sufficiently talented fool!!!!
