Moisture Barrier: A moisture barrier is laminated to Whisper Wool to prevent condensation from contacting the installed flooring and promotes quick and easy installation.

Mold Proof: Antimicrobial treatment prevents mold, fungus, and bacteria growth if airborne spores are present. If other underlays do not specify this treatment, it probably means their product does not include it. Under humid conditions mold spores will grow on any material, such as foam, pvc, and cork recycled textile waste.

Quiet: Laboratory tested sound ratings on laminate of IIC=60, STC=54 are of the highest in the industry.

Resilient: Wool fiber is extremely resilient, long lasting, and won't break down like air products in foam products.

Sound: Absorbs sound energy and mechanical impact energy.

Insulation: Provides thermal insulation.

Size: Individual rolls are 3 feet wide and 33.5 feet long (100 sq. ft.) and is 1/8 inches thick.
