Acoustic enclosures




Sound Insulation with acoustic foam offer the perfect blend of technical specifications and eye-pleasing aesthetics. The increased NRC ratings across the board will meet even the strictest audiophile's needs. Whether you're a professional musician creating a sound studio, or simply trying to help control some sonic anomalies in your hall, gym or church

We offer the complete range of acoustic foam in order to meet your acoustic needs. Order by the pack and/or larger sizes for Note regarding custom cut pieces: We try to provide one seamless piece for your order. However, since this foam is manufactured in pairs, we will sometimes send two pieces of half the size you've ordered

Acoustic foam is not fire retardant. Use at your own risk.

For total sound blocking it is necessary to control the flow of air into and out of a room. Sheet rock walls, ceilings, and floors should be further insulated with 6mm. Acoustic foam is best applied to your walls and surfaces with a heavy staple gun or our adhesive spray. Remember, most acoustic sheets larger than 82" x 96" will have seams. During the vacuum packing process (for shipping) these seams can open. It is recommended that you purchase a can of foam glue to mend any seams that may have ripped during shipping.


Acoustic absorption is the key to this line! Go with our 2" Wedges when you're trying to tame frequencies in smaller areas. These are our most popular seller and work great with most acoustical needs. Our 3" Wedges are better at absorbing low-end frequencies than the 2" version. Medium sized areas will appreciate the acoustic accuracy of the 3" wedges. 4" Wedges are best for larger sized areas with bass control issues. If you need maximum acoustic control and sound accuracy, 4" is the size for you.

In general, the pyramids are better at diffusing sonic anomalies than their wedge counterparts. By having 4 sides exposed, as opposed to 2, sound absorption is reduced while sonic accuracy is heightened. Pyramids will produce a much richer, more complete sound than wedges. Go with the larger sizes when battling against the undesirable sonic effects that bigger rooms pose.

The Noise Reduction Coefficient (commonly abbreviated NRC) is a scalar representation of the amount of sound energy absorbed upon striking a particular surface*. An NRC of 0 indicates perfect reflection; an NRC of 1 indicates perfect absorption

* In particular, NRC is the average of six sound absorption coefficients of the particular surface at frequencies 125 Hz, 250 Hz, 500 Hz, 1000 Hz, 2000 Hz and 4000 Hz. These frequencies encompass the fundamental frequencies and first few overtones of typical human speech. Therefore, the NRC provides a decent and simple quantification of how well the particular surface will absorb the human voice.
