Carpet underlayment

Product catalog summary

Overview
SOUNDOWN Acoustic Carpet Underlayment is designed to reduce noise in boats, particularly in living areas where flooring is a significant noise source. It is easy to install and can be used at any stage of the insulation process.

Specifications
The underlayment consists of a foam layer and an acoustic vinyl barrier. The foam decouples the mass layer from floor vibrations, effectively blocking noise from structureborne or airborne sources. It is available in various configurations with different weights and thicknesses:

2 lb/ft², 1/2” and 1/4” thickness
1 lb/ft², 1/2” and 1/4” thickness
0.5 lb/ft², 1/2” and 1/4” thickness

Physical Properties

Thickness: 1/4” to 3/4”
Weight: 0.55 lbs to 2.2 lbs per ft²
Flammability: Specific data available upon request
Specific Gravity (Barrier): 1.80 (ASTM D 798)
Hardness (Barrier): Shore A 90 Nominal (ASTM D 2240)
Stiffness (Barrier): 19.60 MPA (ASTM 749)
Tensile Strength (Barrier): 407 PSI (ASTM D 412)
Elongation (Barrier): 120% (ASTM D 412)
Tear Strength (Barrier): 77 lbs/1” (ASTM D 624)
Temperature Range: -40 to 255 degrees Fahrenheit

Performance
The underlayment enhances noise reduction, especially when used as part of a full insulation package. It is effective in sealing areas prone to leakage, such as hatches, and provides additional noise attenuation when combined with engine room insulation.
