    Safe Glazing

    Safe glazing


    Accident prevention and break-in protection come first: Aluminium and Glass Entrance Doors fulfil the highest demands of design and security. The 8-mm-thick laminated safety glass on the interior and exterior of the insulated glazing provides maximum security. In case of breakage, the glass splinters are bound and stay adhered to the plastic film on the inside, ensuring that there is no danger of being injured by the shards. Furthermore, the laminated safety glass offers better protection against burglars, because it makes reaching through more difficult.



    Thanks to a highly insulated edge compound with thermal break (warm edge), the glazing offers high thermal insulation for effective energy saving and high acoustic insulation for more peaceful living conditions.
