The basic concept of barrier security is simplicity and security film laminates provide a cost effective way to simply and drastically improve the strength of the building perimeter by transforming ordinary glass into formidable transparent armor. Whether the threat is from forced entry by thieves, the forces of nature, or from the risk of a terrorist bomb attack clear security laminates provides peace of mind for occupants.
After three major losses the customer installed PDBL16. This attack was four hits from a cement block and the glass was intact with bandits fleeing. No further attacks in five years.
Observed by an outside camera the attacker used a baseball bat to strike the glass once in a "homerun" hit. The glass break detector triggered the outside siren and the bandit fled without penetrating the perimeter.
Transparent thin sheets of polyethelene terepthalate P.E.T. are bonded together in a lamination process using water clear acrylic adhesives and a scratch resistance coating on the inside surface. A final thicker coating of adhesive is covered with a release liner which is discarded at installation. Film laminates are pre-cut to the exact glass size and applied edge to edge on the inside glass surface. Glass is thoroughly cleaned and sprayed with a mounting solution and the pre-cut laminate is expertly fitted to the glass. The fitter using a proscribed method bonds the laminate to the glass using a polyurethane edged tool using high pressure. Performance is determined by drying time which varies depending on temperature and exposure to sunlight.
Glass at the breaking point, called the modulus of rupture bends slightly and the adhesives in the security laminates absorb the resulting energy re-directing the shock through-out the whole glass surface with the thickness of the film providing a mechanical barrier to prevent penetration of the glass/film structure.
Overall thicknesses vary from 6 mils to 21 mils (1 mil = 1/1,000 of an inch) with thicker films performing best against forcible entry attempts. The adhesive formula and thickness is critical. The adhesive must remain pliable even years after installation. The thicker the adhesive base the better the shock absorption ability. However few manufacturers have mastered the subtle challenges of security film lamination and choose to use the same adhesives as used on thin tint films

Opaque films completely block viewing through glass providing privacy while allowing transmission of light. Reflective films allow a view from one side while blocking the view from the other side. Light biasing is a very important consideration for one way viewing and should be discussed at length.
Perfect Defence Inc. ® offer a complete range of solar control films that reject both ultraviolet and infrared wavelengths and can drastically reduce the heat loading through glass. In addition to marked improvement to the comfort of occupants significant savings are realized by reduced air conditioning costs.
