MP Global Products' new LuxWalk underlayment for Luxury Vinyl Flooring.

MP Global Products' new LuxWalk is a sound-suppressing underlayment for floating or glue-down Luxury Vinyl Flooring (LVF).

According to the company, LuxWalk is a great match for condos, high rise apartment complexes, and anywhere else where sound control between floors and excellent IIC and STC sound test ratings are considerations, LuxWalk is designed and engineered to soothe impact sound and floor to ceiling noise.

At 25/1000 inch thickness and featuring a smartly engineered heavy duty design, LuxWalk adds cushioning under LVF and retards movement of LVF installed over it—helping reduce abrasion of the underside of the LVF.

Made from polyethylene film that incorporates blended recycled polyester fiber (derived from soda bottles diverted from landfill) with hot-melt adhesive, LuxWalk, with 31% post-consumer recycled content, is LEED compliant and will contribute to MRc  4.1 - 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 millimeter luxury vinyl planks installed over LuxWalk and six inch concrete with suspended ceiling achieved a 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 millimeter luxury vinyl planks over LuxWalk and six inch concrete with suspended ceiling achieved a rating of 66.

"Both these rating are appreciably higher than the ratings of 50 that the IBC (International Building Code) suggests," said a company representative. 

LuxWalk’s sound test results provide documentation that can be shared with building inspectors who are evaluating sound suppression, whether or not the manufacturer of the luxury vinyl flooring has, independently, tested for sound reduction. 

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