Sliding soundproof airtight door – SP450 STILLROOM®

The SP450 STILLROOM® airtight door was developed to offer a door that is both airtight to guarantee the containment of sterile environments or those sensitive to bacterial or particulate contamination, and which, at the same time, provides high performance acoustic insulation.

It is designed for surgical suites, sterile areas, disinfection rooms and other controlled environment areas.

The performances of SP450 STILLROOM® airtight doors have been tested by certified test laboratories, which have issued airtightness and acoustic insulation certificates.
