industrial and commercial applications. Doors can be
supplied to meet fire resistance.
Performance
Yokah acoustic doors are designed to perform. Our experienced acoustical engineers have produced innovative designs, which are combined with state-of-art sound reduction technology. This combination produces dramatic sound reduction properties at an affordable cost.
We use high-quality materials combined with precision
manufacturing techniques, to ensure that exacting
production quality standards are maintained. Sound
reduction materials developed for use in the aerospace
industry are precisely blended with superior design to
produce products with unparalleled sound reduction
qualities.
YOKAH acoustic doors offer STC rating of up to 53 in
accordance with the most recent ASTM E-90 standards
and are tested at Architectural Testing, Inc. Doors can
also be supplied to meet BS476: Part 22: 1987 and for
periods up to and including 2 hours integrity fire
resistance.
Sound-performance field test, however, is the only certain way of ensuring your complete satisfaction. We guarantee that our door assemblies, when correctly installed, will be within 5 rating units of the STC laboratory figures. Call your local representative or our
customer service department for specific details and for assistance in properly choosing the correct STC
system for your project.
