After many years of vandalism, the Head of School Security Jimmy Månsson - who has several years of good experience with Hammerglass - decided to install unbreakable Hammerglass in all windows in this new construction.
Hammerglass Insulate is an excellent choice against vandalism and burglary. The system is approved according to EN 356 up to Security Class P8B in the configuration /6mm Hammerglass/12mm gap/4-4-1 laminated glass/.
