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.

    Exactly as advertised and shipping was very fast. Turned these into acoustic panels for a studio and could not be happier with the results. Absorbs low frequency better than expected! Thanks!

    Excellent low frequency absorption at an affordable price

    Posted by Robert on 22nd Jun 2020

    I have bought nine bats of the 4# 4 inch mineral wool insulation for low frequency absorption in my studio control room. The absorption coefficient is excellent and that was a huge surprise to me as I was skeptical with the affordable price. I will be buying much more for ceiling clouds and wall/ceiling corners in the near future.

    The only con is that the insulation comes directly boxed with no wrapping , so you do not know if it is thermafiber or rockwool, but thats not as big of a deal since it works.

    Using these is the most economical way to make sound absorbing panels to stop unwanted sound reflections off wall, ceilings. Very effective for my stereo system.

    These 4 inch thick panels really soak up the sound! I built nine panels so far and I’m already thinking about building more.

    Awesome Sub-Bass absorption made here.

    Posted by Rick D. on 5th Aug 2019

    I put these sheets of insulation in the cavities behind a pair of large planks,
    I use to hold my consoles...
    covered the openings with upholstered pegboard and Wala!
    Instant sub-bass low frequency bass trap. Sucked up a lot of the
    30 to 100hz range that was muddying the waters.
    Bottom end is really tightening up now....
    This stuff is ideal for maximum low frequency absorption, if you put a
    membrane in front of it. I have another application for this stuff and will
    get another couple of boxes when the timing is right.
    Thanks again BIP, for a great product and great service.
