Specialty Flooring Underlayments
Quality underlayment well matched to the installation can provide several benefits that enhance a hardwood flooring installation. To that end, MP Global Products developed two fiber paddings, Insulayment and QuietWalk, with special characteristics that make them suitable for use under wood floors. Insulayment acoustical underlayment is a high performing, sound suppressing product for installation under glue down or nail down hardwood or engineered wood floors, while Quiet- Walk is designed for use under floating wood and laminate flooring. Both underlayments deliver multiple advantages. They smooth out little subfloor imperfections so the finished floor lays as close to flat as possible. In addition, QuietWalk boasts a “moisture management system” unlike any other underlayment that will handle moderate amounts of moisture from either above or below. In addition, both products quiet impact sound and floor-to-ceiling noise. Insulayment glues onto a structurally solid concrete or wood subfloor, and wood planks adhere directly to it. QuietWalk rolls out and tapes at the seams. Both products take advantage of MP Global’s unique manufacturing process (used in all its fiber padding products) which results in randomly air-laid filaments that cushion the floor and absorb impact sound, enabling the underlayment to act as a highly effective isolation barrier that dampens impact noise traveling from an upper living area to a lower living area. They also maintain excellent compression resistance for the life of the floor and disperse impact energy of each footfall, lessening strain on knee and hip joints and improving overall walking comfort. These two products are firm enough to resist crushing under the weight of the floor, unlike lesser products that can flatten out over time, especially in high-traffic areas. Moisture handling is excellent. In addition to the vapor barrier film on the top-facing surface of QuietWalk, the randomly air-laid filaments can wick subfloor or incidental perimeter moisture and disperse it through the pad. Moderate amounts of moisture will eventually evaporate over time, provided the source of water, such as a leak, is stopped. Insulayment and QuietWalk are quality upgrades from basic products commonly referred to as “2 in 1” polyethylene or polystyrene products and have the added selling point of costing less than froth foam, rubber or cork underlayment that shares similar sound numbers. Both products also have an environmental story. Insulayment is third-party certified to contain 100% post industrial/pre-consumer fibers, while QuietWalk is third-party certified to contain 95% post industrial/pre-consumer fibers. Both are LEED compliant and can contribute to credits in the Materials and Resources category. As well, each has passed California’s Section 1350 for CHPS and Standard Office, the most rigorous emissions test widely recognized around the country. Insulayment and QuietWalk are also approved for use over radiant floors.
