ECOWOOL BROWNIE
ECOWOOL BROWNIE RIGISLAB

ECOWOOL BROWNIE RIGISLAB is designed specifically for press fit installation without the need for stapling or fastening. It can be fitted between timber or steel studs in a wall cavity and ceiling system applications. They resist vibration or shake down and fit readily around uneven surfaces.




  • PROPERTIES
    The slab are compatible with wood or steel studs in ceiling and walls. The sound control batts can effectively increase STC ratings by 8 to 10 points. Use of resilient channels can make wall assemblies even more efficient by increasing STC values by as much as 4 to 5 points depending on the construction:
    • Wood frame construction – residential homes and light commercial buildings
    • Metal frame construction – commercial buildings
    • Manufactured homes – modular or manufactured housing
    • Engineered wood construction – assemblies framed with 305 mm to 488 mm on-center cavities, wide-spaced wood trusses or I-joists
    • Suspended ceiling systems – sized to fit above 0.61m x 1.22m ceiling panels
