Lamvin Dual Core Hanging Baffle Pull Test Press Release
Hanging one or more fiberglass acoustic baffles over an audience or large assembly is potentially dangerous. Yet, regardless of brand, it happens quite often and without anyone giving much objective consideration to the structural integrity of the embedded attachment points in the fiberglass baffles. That is, until now.
Lamvin Acoustical Products, Inc., recently completed certified laboratory pull testing on their Sonic Series, Dual Core hanging baffle suspension tabs, becoming the industry’s first acoustic products manufacturer to complete and publish their results.
It is common practice for acoustical consultants and contractors to specify and install ceiling-mounted acoustic baffles and clouds, some weighing 56 lbs or more. What’s not a common practice is having the embedded attachment points safety tested for pull-out strength. We believe Lamvin is the first and only US manufacturer to do so.
QAI Laboratories in Rancho Cucamonga, CA ran ASTM D 1037-12 attachment security and integrity testing on Lamvin’s popular Sonic Series, 2” Dual Core baffles. ASTM D 1037-12 is a Modified Fastener Withdrawal test used for evaluating the properties of wood-based fiber and particle panel materials – Section 16: Direct Screw withdrawal.
Lamvin’s Dual Core suspension tabs withstand an average load of 131 lbs. per point.
When applied to a 4’ x 8’ x 2” Dual Core baffle, which is one of Lamvin’s heaviest products, QAI’s test results show these 56 lb baffles have an overall safety ratio of 7:1 – when hung from at least three points, which is the minimum number allowed. This means each point is rated at 2.34:1.
Do you have confidence in the structural integrity of your current, or pending, overhead acoustic treatments? If not, now might be a good time to contact Lamvin.
