WINDOWS

Glazed areas are vulnerable and should be kept to a minimum wherever possible. Where glazing/windows are necessary they can be protected by various methods.

Window locks should be fitted to all opening windows, preferably 'frame to frame' designs.

Conventional glazing can be replaced with laminated glass (conforming to British Standard 5051) or a polycarbonate subsuite, beaded internally, to give greater impact resistance in areas prone to vandalism or where valuable equipment may be stored. Used in conjunction with security grilles/bars, this measure will give a good level of protection. It should be remembered that the extra thickness and weight of laminated glass can mean that special frames and fittings are needed.

Externally fitted roller shutters can offer greater protection. As attacks are still made on roller shutters it is recommended that they are connected to the intruder alarm system, to provide an early indication of attack. Some new shutter designs are more attractive to the eye and have also been tested to prevent attack by vehicle. However, planning permission may be required for some forms of shuttering.

Use of shatter and privacy window films should also be considered. Shatter film can be bonded to conventional glazing to protect against glass fragmentation and provide a further barrier. Privacy film provides the facility of one-way vision and can prevent the criminal from surveying the interior prior to entry. This also conceals valuable equipment and assists confidentiality particularly where computer monitors are in widespread use.

Internal grilles or bars correctly fitted, (preferably larger than the window itself), offer a higher standard of protection.
