We've been using this underlayment for two decades with very good results. Unlike most underlayment, this one won't fall apart, crush or disintegrate over time. It holds up well to heavy foot traffic and also has excellent sound deadening qualities. The built-in vapor barrier saves you the step of installing a separate barrier underneath your flooring.

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 will not inhibit transfer of heat; no performance decrease at high temperatures. Note: foil looking covering is actually mylar and not aluminum foil so it won't reflect heat.

• Eco-friendly – 100% recyclable; at least 20% post-industrial recycled content; meet or exceed indoor air quality standard established by CRI Green Label Program
• Easy-to-use – rolls out easily and lays flat

Alert: DeciBlok has a rubber smell when first opened. While it is non-toxic, it may initially aggravate some sensitivities.
