4" Thick 4# Mineral Wool Acoustical Board

4" Thick Rigid Mineral Wool Insulation Boards are used as both acoustical and thermal insulation panels.  The 4" thickness provides both excellent sound absorption (NRC 1.10) and thermal insulation (R Value: 16.8) which makes this a very popular product in both the acoustical field as well as the industrial insulation industry. These mineral wool panels are sold in boxes of 3 panels which are 4" thick and have panel dimensions of 24" x 48".

ACOUSTICAL APPLICATION:
As the Acoustical Performance Chart listed below shows, the 4" Mineral Wool Insulation Boards are superior in sound absorption across the frequency spectrum.  4" Mineral Wool Panels absorb low, mid, and high frequencies which allows these panels to be made into bass traps (low frequencies) as well as Multi-Band Absorbers (all frequencies).  4" Mineral Wool Insulation Boards are the preferred core material for Bass Traps.  The mineral wool insulation is installed inside a frame and wrapped with acoustical fabric and placed in the back corners or back wall of a home theater, sound studio, media room, etc.
