Impact Sound Transmission:
ASTM E492-96, ASTM E989-89 Impact Insulation Class (lIC) = 58
Standard Classification for Determination of Impact Insulation Class designed to measure the impact sound transmission performance of a floor-ceiling assembly, in a controlled environment.
Sound Transmission Loss:
ASTM E90-99, ASTM E413-87 Sound Transmission Loss (STC) = 54
Standard Test Method for Laboratory Measurement of Airborne Sound Transmission Loss of Building Partitions and Classification for Rating Sound Insulation to measure the sound insulation properties of the test specimen,--in a controlled environment.
Installation Instructions:
1. Lay the underlayment on the floor with the Mohawk logo facing up. The direction of the underlayment should_ be parallel to the direction of the laminate floor.
2. For the first row of laminate, the underlayment should be placed so that approximately 1 inch (2 cm) overlaps onto all perpendicular walls. Place the following row next to the first on top of the lower moisture barrier flap.
3. Remove the adhesive strip and fold back the upper flap onto the second row. Make sure that the underlayment fits together tightly (don't leave gaps).
4. On the last row, place the underlayment 1 inch (2 cm) up against the wall. To join rolls on the short side of the underlayment, use a moisture resistant tape to connect the 2 pieces so that water cannot penetrate the underlayment.
