A Quick Guide to Blast Resistant Glass

For a variety of both innocuous and malicious reasons, the modern world necessitates the use of blast-resistant glass more and more often in the design of building façades and interiors. When an explosion occurs, flying or falling glass and debris is the primary cause of damage, injury and death—not the blast itself.

Glass designed to withstand the force of an explosion is not a new development; however, recent technology has enabled glass manufacturers to significantly improve the performance of blast resistant glass to minimise the risk of fatal injury and maximise security.

What is blast resistant glass?

Blast resistant glass offers a substantial, necessary level of protection for people and property in the event of an explosion. Commonly referred to as bomb-proof glass or bomb-resistant glass, blast resistant glass consists of panels of glass that have been treated to resist impact.

They are usually layered with a polycarbonate glazing or laminate. The plastic laminate layer is designed to absorb the shock of an explosion or impact from blasted debris and to hold the glass fragments in place, so they don’t become additional injurious flying debris.

How does blast resistant glass work?

Blast resistance refers to the material’s ability to withstand a high pressure shock of very short duration, rather than withstand a large amount of pressure over time. Depending on the type and thickness of the glass, where it will be installed, the potential for accidental or deliberate explosion and the level of protection needed, manufacturers can specify the composition of the laminate and the design of the glass to offer the protection required.

Blast resistant glass does not remain intact in an explosion – the glass itself will shatter from the force, but the polycarbonate layer applied to the glass will retain the shattered pieces to prevent further injury to people or destruction of property.

Blast resistant glass is designed to work in concert with specially designed blast resistant frames, whether for windows, doors or interior divisions. The frame must be designed and approved for use with blast-resistant glass in order for the glass to be effective, as the frame will hold the bomb-resistant glass piece in place after impact.

Where is it typically used?

Blast resistant or bombproof glass can be used wherever there is a potential for accidental explosions or intentional attacks, such as on job sites where industrial explosions may occur or in targeted buildings like banks.

Windows and glass building façades are the most common uses, but bomb resistant glass can be used in security doors, interior walls or room dividers, glass flooring and anywhere else deemed at risk to explosions.
