GrassWorx Acoustic Matting is engineered to reduce airborne and impact sound between residential floors in apartments and condos—helping create quieter, more desirable living spaces. Our mats are listed in UL-rated flooring assemblies and deliver real-world durability in high-traffic environments.
Choose from our performance-proven product line—SC50, SC190, and SC250—to meet the acoustic demands of your build. Each is manufactured at our U.S.-based facility, ensuring consistent quality, fast delivery, and competitive pricing when you buy direct.
Why GrassWorx?
Smarter Design: Our mats are more rigid than entangled mesh and feature a light-colored backing that reduces heat transfer before gypsum is poured.
Easier Installs: With cleaner cuts, flatter rolls, and reduced matting-to-subfloor contact, installation is smoother and faster for your crew.
Long-Term Durability: Engineered to prevent crushing and resist degradation over time, our mats help maintain floor integrity and reduce costly repairs.
Unlike system-standard mats that require you to conform to someone else’s process, GrassWorx mats give you the flexibility to build to your own standards—with the added benefit of direct-from-manufacturer support.

GrassWorx Acoustical Matting products combine the best materials, engineering and industry knowledge for your project. Don’t overpay for an “all-in-one” product when you can buy the best acoustic control matting component for a fraction of the price. Our patented design achieves the highest results in the industry based upon the standard durability “Robinson” test (ASTM C627).
Our engineers buy the best components and understand the complicated physics of superior sound control to ensure these “highest results in the industry”. We have been proudly manufacturing GrassWorx acoustic mats for over 25 years and our products can be found across the United States.
Each of our three products are manufactured with at least 50% post-industrial recycled materials.
We manufacture in St Louis, MO, supporting local communities, and are able to ship products anywhere across the country easily due to our central manufacturing and distribution location. Don’t go the easy route, install the best and have superior sound control and keep your costs down.
An engineer at Monsanto in their auto headliner acoustics department became aware of a new demand for sound deadening materials. Multi-family apartments were being built in high numbers in Los Angeles, CA. The engineer was aware of the grass-like turf product and helped to create an innovation that would impact building codes in most municipalities going forward. The product structure has evolved over the past 30 years to create a solution that meets the environmental acoustical minimum performance in the current building codes across the U.S. Our current acoustical matting products look nothing like grass…to anyone but us.
Nature-inspired innovations and people with the passion and know-how is what sets GrassWorx apart in every industry in which we compete.
