Acoustement 40

Pyrok Acoustement 40 is a nominal 41 PCF (air-dried density) Portland cement/exfoliated vermiculite spray-applied formulation 100% free from asbestos and mineral fibers, polystyrene, and cellulose. Pyrok Acoustement 40 is highly abuse resistant (impact, abrasion, moisture, hostile industrial environments), has excellent adhesion to a variety of substrates, allows substrates to breathe and be cleaned by a variety of methods.

Pyrok Acoustement 40 can be used as a decorative surfacing material or as a combination of these qualities even in conjunction as a fireproofing material.

This material is recommended for exterior exposures where resistance to environmental pollution, rain, corrosion, and spalling is required. It may be used in interior exposures where superior abuse resistance is required.

Typically Pyrok Acoustement 40 is specified for transportation facilities, correctional projects, lobbies, atriums, tunnels, natatoriums, gymnasiums, manufacturing facilities, contact wall areas, and any other area requiring high abuse resistance and sound absorption qualities.

It can also be used on interior surfaces of walkways, hallways, and rooms where a purely decorative finish is desired.

Pyrok Acoustement 40 may also be used on ceilings as a combination acoustical finish and fireproofing material.

Custom integral coloration is available within the limits of iron oxide pigmentation.

Pyrok, Inc. recommends application of Pyrok Acoustement 40 be performed only by approved Pyrok applicators. An approved applicator list is available from Pyrok, Inc.
