Based in Maple Heights, Ohio, SAPboard is a subflooring system developed by RSP Industries for use in the construction market. It serves as an alternative to traditional cementitious underlayments and includes an integral sound mat to address acoustics. The system is described as achieving sound absorption of up to 59 IIC and 62 STC. It is designed to limit noise transmission between living spaces, a common concern in multi-unit and hospitality projects, and can be installed during framing, allowing sound barriers to be built in without demobilizing trades to pour gypsum concrete.

The target market includes architects and builders working on larger structures such as multifamily dwellings and hotels, where floor-to-floor sound transfer is a key issue. The product combines the convenience of subfloor installation with acoustic isolation capabilities, offering installation benefits. The company positions itself in the construction industry with a focus on integrated sound control during framing, aiming to streamline project workflows in environments with strict acoustical requirements. SAPboard is produced by a small team based in Maple Heights, Ohio.
