MP Global’s LuxWalk Achieves Impressive IIC and STC Sound Test Ratings

| MP Global Products' LuxWalk has achieved impressive IIC and STC sound test ratings. |
LuxWalk, a new underlayment from MP Global Products, engineered specifically to cushion floating or glue-down luxury vinyl flooring (LVF) and to soothe impact sound and floor to ceiling noise, has achieved impressive IIC and STC sound test ratings, according to the company.
In a recent IIC test, designed to measure in a laboratory environment the impact sound transmission performance of LuxWalk installed under 5mm floating luxury vinyl tile (LVT) over 6-inch concrete with no ceiling, the assembly achieved a sound rating of 52—higher than the rating of 50 that the International Building Code (IBC) suggests.
Additionally, in a recent STC test, which evaluated the ability of LuxWalk installed under 5mm floating LVT with no ceiling, the assembly also achieved 52.
With thinner LVT, the numbers are higher yet: In the IIC test using 4.2mm luxury vinyl planks installed over LuxWalk and 6-inch concrete with a suspended ceiling a sound rating of 72 was achieved. In the STC test, the 4.2mm luxury vinyl planks over LuxWalk and 6-inch concrete with suspended ceiling achieved a rating of 66.
LuxWalk’s sound test results provide documentation that can be shared with specifiers, owners, and building inspectors at commercial or multi-family housing projects who are evaluating sound suppression.
"At 25/1,000-inch thickness and featuring a smartly engineered heavy duty design, LuxWalk adds the right amount of cushioning under LVF, which can otherwise easily compress to the base on which it rests when pressure is applied to it," said a company representative. "LuxWalk minimizes impressions and indentations that can occur in the finished floor and retards movement of LVF installed over it, helping reduce abrasion of the underside of the LVF."
According to the company, LuxWalk also carries a Water Vapor Transmission Rate of .273 grams per 100 square inch per day.
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.
