well as through the floor to living spaces below
• Use under ceramic tile, stone, marble, engineered hardwood and
laminate floors
• Acts as a crack isolation membrane that resists transfer of stress
cracks from subfloor through to flooring surfaces
• Reduces thermal transmission, increasing the effectiveness of
floor heating systems
• Each sheet: 2' x 3'

* IIC measures sound such as moving furniture and walking, STC measures sound such as voices and television. Minimum sound rating required by most building
codes and architects is 50. R-Value is the rating used to measure resistance to heat flow. Δ Delta Rating is the only true measurement of sound reduction from a
product (not a floor assembly) in the industry.
