CityLam – Clear Laminates

The modern architect and designer have many facets of security to keep in mind in the early stages of their drawings, without the use of unsightly burglar bars. Furthermore the design professional needs to ensure that the occupants of the building have a necessary escape route in the event of a fire.
So therefore, added to this dimension the amount of natural light needs to be taken into consideration. The answer lies with CityLam and the use of a clear or tinted laminated safety glass

N.B. The size of the hole at penetration point is approximately 50mm in diameter. Many more blows are required to gain access.

Whilst glass offers a wonderful aesthetic appeal, architects and professional designers need to be aware of a number of safety features and factors not only in the office environment but also in the home. If the Laminated glass is broken, the glass will adhere to the PVB interlayer and should generally stay in the frame to give added safety rather than falling free and causing potential injury with flying glass shards.

By increasing the PVB interlayer the safety risk rating is achieved in the following detail:
