Window glazing EI30, EI60, EI90: Fire protection standardised all-glass walls
Fixed viewing windows without window sashes are an architectural element that is valued in many places in office and administration buildings as well as in sports stadiums and school buildings. Besides a great deal of natural light, the fixed glazing from Bühlmann brings improved fire protection and noise insulation into living and office space. Our fixed glazing with fire protection glass is also often used as fire protection building components in stairways and corridors with an escape route.
