TOWER entrance doors have increased acoustic isolation (the result gained during tests in Centrum Techniki Okrętowej, Ship Design and Research Centre, in Gdansk was 41 dB). They are provided with four dead bolts and two steel metal plates inside the door wing. Such doors can be chosen either with steel door frame or MDF board.
Entrance doors accordingly to the name separate rooms within premises from outside. This can be either a staircase or entrance to another complex of offices within a bigger building. Entrance doors are used in places which require increased acoustic isolation or anti-burglary standards.
Provided is the choice of both natural veneer, timber, gloss and painted door coatings. One can also decide about the kind of door frame, either steel or MDF one.
