ASSA ABLOY Group Brands Frameworks, Graham and Maiman have teamed up to launch Serenity, a wood door and aluminum frame sound-rated door opening solution.
Available in sizes up to 9 feet, the wood doors and aluminum frames, along with PEMKO seal kit, have been acoustically tested together, to achieve an STC (Sound Transmission Class) rating of 35 per ASTM E90 (Standard Test Method for Laboratory Measurement of Airborne Sound Transmission Loss of Building Partitions and Elements) and ASTM E413 (Classification for Rating Sound Insulation).
The Serenity opening is available in various wood door options from Graham and Maiman, including a 20-minute fire rating, with any commercially available veneer, and must be ordered with a Frameworks Type II aluminum frame.
