Underlayment

Sponge Cushion Inc., DeciBLOK

Colors:

High-performance acoustic underlayment

Our popular underlayment, DeciBLOK provides great support, sound insulation and durability for flooring. DeciBLOK™ acoustic wood, engineered wood, and laminate floor cushion, is composed of a lightweight, cellular sponge rubber mat, that is layered between two polyester non-woven films. It is designed to reduce flooring noise by dampening impact effects and by isolating sounds to the room where they are created. It is antimicrobial and non-allergenic; plus it inhibits and retards micro-organisms, odors, mold and mildew. DeciBLOK is also available with a moisture vapor barrier for concrete subfloors.

DeciBLOK's good memory prevents compression, and its low R-value makes it ideal for floating floor installations over radiant heat. It can also be glued down for even better sound quality and further reduction of impact noise.

DeciBLOK is very easy to use; simply roll it out and cut it with a razor blade to fit the room. It has a slight rubber smell when first out of the package, but this goes away and leaves no trace once covered with a floor. Completely non-toxic, it doesn't contribute to indoor air pollution. CRI Green Label Certified for indoor air quality.

DeciBLOK with Moisture Barrier is also available.

Why we like it

We've used this since 1991 underneath our radiant-heated floating floor. It doesn't compress, crumble, disintegrate or out-gas like most foam pads. It also allows heat to easily pass through.

Features & benefits

  • Long-lasting — highly stable; will not crumble and maintains elasticity through years of service
  • Non-toxic — uses food grade polymers used in chewing gum; antimicrobial and non-allergenic
  • Safe — for everyone, including the chemically sensitive; learn how to test a non-toxic product for tolerance
  • Mold-resistant — inhibits and retards micro-organisms, odors, mold and mildew on or below grade applications
  • Radiant heat safe — low R-value of .10, will not inhibit transfer of heat; no performance decrease at high temperatures
  • Installs anywhere — can be installed above or below grade, over any sub-floor
  • Eco-friendly — 100% recyclable; at least 20% post-industrial recycled content; meets or exceeds indoor air quality standard established by CRI Green Label Program
  • Easy-to-use — rolls out easily and lays flat

Alert: This pad has a rubber smell when first opened; however, the odor is non-toxic. Like all products, it should be pre-tested if you're chemically sensitive.
