One of the most critical areas in acoustic insulation of areas which house engine test benches, generators, air compression units or acoustic laboratories, is undoubtedly the doors, the gates and the windows. All these components must have noise reduction standards identical or superior to those of the walls, the ceilings and the walls which form the room itself. Bosco Italia doors and windows guarantee the highest levels of noise reduction (Rw - 40 - 50 - 60 dB).

DOORS AND GATES

They are built in very thick steel with one or two doors. The doors are padded with soundproofing materials and fitted into a very strong frame bolted to the brick walls of the chamber.

Roll-up Door shutters

applications:
Sound insulating roll-up shutters, are used to soundproof the opening spaces of industrial buildings whenever it is difficult to use traditional doors.

advantages:
•Drastic reduction of structural dimensions;
•Employment flexibility;
performances:
•Attenuation = RW 35 dB.
•Resistance to windforce = 700 N /mq.
•Speed of opening is of 0,6 mt/sec.
construction:
Hallington Roll-Up Doors shutters are made of overlapping elements. Every element is self-porting, monolithic and sound-insulating, and has the following dimensions:
Height = millimeter 600 x Length = mm.3.000 - 4,000 - 5,000 and Thickness =mm.100.
