Entrance metal doors with glass produced by Steel Line company are safe and reliable. Such doors have three-chamber glazed windows with energy-saving spacer that retain heat in the building and provide high rates of noise insulation.
For safety sake we use anti-shattering glass coated with protective cover. It is able to withstand the blows from which normal glass would be shattered immediately. Due to the strong adhesion of the adhesive glued layer the coating is firmly attached to the glass so that even if the glass gets shattered, the pieces will remain glued together.
The glass has mirror tinting that gives the effect of a one-way visibility.
