For more than 20 years, we have taken what is discarded and may be deemed as trash to some and have embraced those raw unwanted materials as our way of business. We are problem solvers, innovators, and an eco-aware company with environmentally friendly, high-performing fiber acoustic floor underlayment products for laminate, flooring underlayments for tile, and flooring underlayments for hardwood. We were 'Green' before it was even fashionable. Our QuietWalk® brand rapidly became a leading laminate floor underlayment for the entire floating floor underlayment industry. At first, our competitors scoffed at our 'ugly' underlayment, but today they are scrambling to invent their own green flooring underlayment story.
Our flooring underlayment options are specifically geared to address moisture protection, sound deadening, and sustainability. Many of our floor underlayment products meet the most rigorous independently certified indoor air quality standards.
Today, more than ever, architects and designers specify and recommend our flooring underlayment products for home construction, commercial, high-rise apartment complex or condominium.
