Hammerglass Single

Hammerglass - Single Glazing

If aesthetics are an issue when selecting the type of window protection to install at your establishment, then Hammerglass offers the perfect solution. It provides an invisible deterrent against vandalism and casual intruder entry, looking like standard glazing from a distance.

Hammerglass offers virtually unbreakable, bullet and blast resistant* glazing solutions to anyone in need of protection against broken glass and burglary. Our customers include local authorities, schools, shops, businesses, public buildings and individuals who face high costs for replacing glass panes after vandalism and burglary attempts.  (*non-scientific test)

What Is Hammerglass?

Hammerglass must NOT be confused with regular polycarbonate.  Regular uncoated or thin coated polycarbonate quickly becomes yellow and abrades easily over time.  Hammerglass is a specially coated polycarbonate sheet and its coating consists of a silicone oxide layer, which is similar to glass. This combination provides unique qualities.
