MP Global introduces premium acoustic underlayment for LVF

[Norfolk, Neb.] MP Global announced the introduction of LuxWalk, a sound-suppressing underlayment for superior performance under floating or glue-down luxury vinyl flooring (LVF).

According to the company, at 25/1000” thickness and featuring a smartly engineered heavy duty design, LuxWalk adds the right amount of cushioning under LVF. It also retards movement of LVF installed over it, helping reduce abrasion of the underside of the LVF.

Because luxury vinyl flooring can easily compress to the base on which it rests when pressure is applied to it, underlayment with good compression resistance is important. LuxWalk, which has great compression resistance testing results (exceeding test machine limits), it enhances LVF’s performance, minimizing impressions and indentations that can occur in the finished floor.

Made from polyethylene film that incorporates blended recycled polyester fiber (derived from soda bottles diverted from landfill) with hot-melt adhesive, LuxWalk, with 31 percent post-consumer recycled content, is LEED compliant and will contribute to MRc 4.1 to 4.2 credits.

In the IIC test, designed to measure the impact sound transmission performance of a floor-ceiling assembly in a controlled laboratory environment, 4.2 mm luxury vinyl planks installed over LuxWalk and 6” concrete with suspended ceiling achieved an impressive sound rating of 72.  

In the STC test, which measures the sound-insulating property of a partition element expressed in terms of the sound transmission loss, 4.2 mm luxury vinyl planks over LuxWalk and 6” concrete with suspended ceiling achieved an outstanding rating of 66.

LuxWalk has full film coverage and carries an excellent Water Vapor Transmission Rate of 273 grams per 100 sq. inches per day, improving the way LVF handles potentially harmful moisture.
