Offers the best support, moisture protection and sound absorption for your floors.

ADVANTAGES

• • Reduces floor noise by providing excellent sound absorption

• • Provides cushioned comfort under laminate and floating wood floors

• • The Silencer SR™has high density and compression resistance properties that enable your floor to perform to its fullest potential and last a lifetime

• • The moisture barrier film and tape strip combine to lock out moisture and allow for quick and easy installation

• • Eliminates minor subfloor imperfections

• • Contains ultra•fresh™ anti-microbial which resists mold, mildew, and bacteria

• • The Silencer SR™ adds insulation value with an R-value of .205

• • Suitable for use with radiant heat flooring systems

• 100% recyclable, environmentally friendly, non allergenic and odorless

APPROVED SUBSTRATES

• • Dry, completely cured concrete (at least 14 days old with HVAC operating)

• • 3/4″ interior plywood or OSB flooring

• • Waterproofing and crack-isolation membranes

• Cement backer units

FLOOR PREPARATION

• • Subfloor should be clean and dry

• In geographic areas where concrete subfloors are subject to excessive moisture, a calcium chloride moisture test is required. Vapor emission readings in excess of 4 lbs. per 1,000 square feet in 24 hrs will require additional protection such as concrete sealant or polyethylene sheeting.

INSTALLATION Quick and easy installation* – requires no additional seaming tape, cuts with a knife

1. 1. Install The Silencer SR™ with film DOWN on subfloor

SOUND ABSORPTION PROPERTIES
Impact Insulation Class (IIC) This method is to measure the impact sound transmission performance of a floor-ceiling assembly (sound transmission through the floor)
IIC – Flooring – Sub-Floor
70 – Laminate/Engineered – 6″ concrete with ceiling assembly
59 – Hardwood – 6″ concrete with ceiling assembly

Sound Transmission Class (STC) This method is to measure the air-borne sound insolating property of a partition element for effectiveness in blocking sound
STC – Flooring – Sub-Floor
71 – Laminate/Engineered – 6″ concrete with ceiling assembly
53 – Hardwood – 6″ concrete with ceiling assembly

Delta IIC The db rating difference between a floor measured with an underlayment and with no underlayment
Δ IIC 22
