Designed for use in single-family and light commercial construction. Also ideal for renovation projects.

Product Description

The next generation in underlayment performance is here. Gyp-Crete 2000® now delivers compressive strengths between 2000 psi (13.8 MPa) and 3200 psi (22.1 MPa), enhanced resistance to surface abrasion, and even faster drying time. It's ideal for use over wood subfloors in single-family, light commercial and multi-family construction, as well as renovation projects. Its crack-resistant surface provides a perfect base for practically any floor covering.

FSTC - Field Sound Tranmission Class in accordance with ANSI/ASTM E 336 and E 413.
STC - Sound Transmission Class in accordance with ASTM E 90 and E 413.
IIC - Impact Insulation Class in accordance with ASTM E 492.
FIIC - Field Impact Insulation Class in accordance with ASTM E 1007 and E 989.

All acoustical testing was done by Riverbank Testing Laboratories; Intest, Inc.; or Twin City Testing Corporation. For type of floor covering used, channel spacing and other information, contact Maxxon for test reports by number. For good acoustical performance, the selection of a floor/ceiling system attaining a minimum 60 STC and IIC is recommended. Systems attaining ratings less than 55 STC and IIC provide only marginal acoustical performance. The Maxxon floor underlayments and Acousti-Mat® are but single components of an effective sound control system. No sound control system is better than its weakest component. Care must b taken in the installation of all components of construction to assure the ultimate designed acoustical performance.
