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.

The cost of an attack with broken glass is high and can be an inconvenience: 

  • Security company emergency call
  • New window pane m2
  • Installation

Moreover, in the case of a burglary:

  • Stolen damaged inventory
  • Insurance and police declaration
  • Cleaning costs
  • Work hours lost
  • Psychological distress

Recommended uses

Schools, shops, shopping malls, public buildings, office blocks, petrol stations, pharmacies, bus shelters, media display cabinets – or anywhere you want to protect against vandalism or break-ins.
