Norfolk, Neb.—LuxWalk, a new high-performing underlayment engineered specifically for floating or glue-down LVT that effectively soothes impact sound and floor to ceiling noise, has delivered impressive numbers in IIC and STC tests.
In a recent IIC test designed to measure the impact sound transmission performance of LuxWalk installed under 5mm floating LVT over 6-inch concrete with no ceiling, the assembly achieved an excellent sound rating of 52, appreciably higher than the rating of 50, which the International Building Code (IBC) suggests.
In addition, a recent STC test that evaluated the ability of LuxWalk installed under 5 mm floating LVT with no ceiling achieved the same outstanding rating of 52.
With thinner LVT, the numbers are even higher. In the IIC test, 4.2 mm luxury vinyl planks installed over LuxWalk and 6-inch concrete with a suspended ceiling achieved a noteworthy sound rating of 72. In the STC test, 4.2 mm luxury vinyl planks over LuxWalk and 6-inch concrete with a suspended ceiling achieved a noteworthy rating of 66.
