Safety & Security Glass


Surely this is a familiar site. A broken toughened pane of glass at a phone box. Not nice to look, a complete mess but very safe. Toughened Glass is a safety glass that shatters into millions of tiny pieces. The reason for this is so big shards of glass that can cause the most severe damage are eliminated.

Toughened Glass is approximately seven times stronger than normal glass, and has a very good bounce type of property. That means when fitted in patio or french doors it resists things like footballs and bangs from soft plastic toys and furniture quite well. Its also a requirement in low level windows below 800mm and up to 300mm surrounding any door.

Any type of Glass can be toughened,Obscure patterns are just as easy to get toughened as the process of heating up and cooling down are done the same way. Every pane of toughened glass must have the safety standard kite mark shown in the corner. This can vary with different manufactures, but it should be acid embossed or screen printed so it cant be removed. And be marked BS6206/A.

Toughened Glass can be Laminated together to take security to another level if required. These type of applications are required on buildings and lifts. If a pane were struck on the corner and shattered then the clear butyl sheet that is bonded to both panes keeps all the glass together.


Laminated glass is two or more panes of glass bonded together with interlayer(s) of polyvinyl butryl(pvb). The interlayer keeps the glass together and can also distribute impact energy, giving valuable resistance against attack. When broken, cracking is typically limited to the ares of impact. Laminated glass can be glazed within 24 hours. This is a true safety glass and meets BS 6206 requirements.

Ordinary annealed glass breaks easily. Tempered glass, while stronger, shatters under a greater impact. But laminated glass is different. If laminated glass is broken, the vinyl interlayer remains in the frame, with glass fragments adhering to the interlayer. This provides a strong barrier against forced entry and cannot be cut from one side only, which renders glasscutters useless.

Laminated glass is normally used when there is a possibility of human impact or where the glass could fall if shattered. Skylight glazing and automobile windshields typically use laminated glass. In geographical areas requiring hurricane-resistant construction, laminated glass is often used in exterior shopfronts, curtain walls and windows. The PVB interlayer also gives the glass a much higher sound insulation rating, due to the damping effect, and also blocks 99% of incoming UV light.

The brilliant invention of laminated glass came about over 100 years ago, when a French chemist accidentally dropped a glass flask. The flask had, by chance, become covered with a material that was similar to the present day PVB, and the chemist - noticing that it did not break - was inspired to look further into the reasons.

Tinted Glass

Usually given a bronze, grey or blue cast, tinted glass dramatically cuts glare and heat from the sun (solar gain) yet only slightly reduces the amount of light admitted into your home. Where sun-caused fading or damage may be a serious problem, such as at unprotected south-facing windows, you may want to opt for glass with a solar bronze, grey or blue tint to reject UV rays.
