An installer tapes down Keene Building Products’ QQ Step Soft Rubber Sound Control Mat.


The sound control products segment has become increasingly competitive. A category that previously was limited to underlayments and mats has grown to include adhesives and cushion products. With so many new products in play, contractors need to be extremely careful when choosing products for a specific project, companies in the segment say. Sound control products are not intended to be a one-size-fits-all solution.

“We realize that one product cannot solve all noise issues,” said Bill Devin, manager and director of marketing for Sound Seal’s Impacta underlayment business. “So we have probably 15 different underlayment systems. Our system for marble, for example, is completely different than our system for glue-down vinyl. And, that is completely different than our system for loose-lay vinyl.”

He also believes it’s important to work with an acoustical consultant on every job, to ensure the customer is getting the right product for the building. “Every job we do we run by an acoustical consultant,” Devin explained. “In the end, it can save people significant amounts of money down the line. Sound control shouldn’t be looked at as a temporary solution. It should last longer than the floor.”

Installed acoustical systems need to meet two building codes: IIC and STC. IIC (Impact Insulation Class) measures how well an assembly affects impact noise (for example, the sound of a woman in high heels walking on hardwood). STC, or Sound Transmission Class, measures how well an assembly reduces airborne noise, such as a loud television, radio or conversation.

However, according to Ellis Ponton, vp sales for Keene Building Products, even those relatively straightforward codes can prove confusing. “The IIC rating is the one everyone is looking at for impact reduction,” he noted. “But products do not carry an IIC rating. Only an assembly does. That’s a common mistake – general contractors and architects often ask what the sound rating or decibel rating is on a product, instead of the assembly.”

His company makes the QQ Step Soft Rubber Sound Control Mat, which is made using primarily recycled rubber. “It’s important to find ways to drive cost,” he said. “I don’t mean unit cost – I mean we have to look at the overall assembly, the cost of ownership, and the total cost of installing it. We’re trying to find ways to make the product easier to install, and are looking at ways to get better performance out of even thinner material. However, there are limitations to what you can do. You can’t go against the basic physics involved to deaden sound.” -Michael Chmielecki

Product Names: QQ Step Soft™ 1mm to 8mm are sound deadening products designed for use with the Quiet Qurl® system where hard surface flooring will be used. Recommended as a means to suppress cracks in tile applications while controlling impact noise, especially at the high frequencies. The recycled rubber mat can earn LEED credits; its composition is 100% recycled rubber. Quiet Qurl® 55/025 MC MT is a nominal 0.25”, random filament, corrugated, “U” Groove core sound control mat designed to limit impact noise between floors. Layers consist of a moisture control fabric, entangled net core & white polyester fabric. The point bonded, moisture resistant fabric is laminated to the surface so that gypsum concrete & other materials can be used to create a floating floor. On the bottom side is a highly compressible bonded polyester fabric. Quiet Qurl® RF is an alternative for all three versions of the standard Quiet Qurl product. It is designed for use when the gypsum concrete pour is not to standard thickness (1” with QQ 55/025, 1.5” with QQ 60/040 and always with QQ 65/075). The product combines a fiberglass fabric and a fiberglass scrim together, in combination with the standard entangled net core material. A fiberglass fabric is laminated to the surface so that gypsum concrete or concrete can be placed to create a floating floor. Quiet Qurl® Reinforcement RWT-040 is a 0.375” (9 mm), random filament, geometric patterned core crack suppression mat used to reinforce gypsum concrete & many types of concrete in thin applications. The 3/8” (8 mm) thickness product provides the added strength needed in the assembly when the gypsum concrete is less than traditional 1½” (50 mm) topping
