Acoustic & Vapor Barrier Underlayment – OmniChoice Vapor Bloc

OmniChoice Vapor Bloc is the high-performance "peace-of-mind" solution for condo owners and health-conscious renovators who want to silence their space while protecting their floors. This antimicrobial underlayment combines high-density memory foam with an integrated polyethylene vapor barrier to stop moisture in its tracks—protecting against up to 10 lbs of vapor transmission. It is best used in multi-level apartments and condos under laminate, LVP, or hardwood to meet strict building sound codes while providing a plush, premium feel underfoot. You choose Vapor Bloc not just for its impressive IIC 73 sound rating, but for its eco-friendly, LEED-contributing composition that ensures your indoor air quality remains as pristine as your new floors.
