ACOUSTIC CONSIDERATIONS
When noise reduction within a building is required TC-417 GP is an excellent choice. It exhibits the following acoustic attributes:

NRC (noise reduction coefficient):

ASTM C-423 90a 1.00 @ 2" / 50 mm.

ISO 354 0.95 @ 2" / 50 mm.

Excellent STC (sound transmission control) in wall, roof or floor assemblies when used in conjunction with other materials as determined by competent authorities.

Note! Effective acoustic control in any building is very largely based on a thorough understanding of its particular acoustic problems and the methods and materials needed to control them. Therefore, we strongly emphasise that no decision to use TC-417 GP thermal and acoustic insulation as an acoustic installation in any building be made until:

Our relevant test data is obtained (see below);
A qualified, local acoustic engineer, familiar with the project, be retained to interpret our data and to make recommendations concerning the use of our material.
