28 oz. Tube Acoustical Curtainwall Sealant (12 Tubes Per Case) | TRMACCW-QT

Tremco Acoustical/Curtainwall Sealant was developed for acoustical sealing of drywall partitions, curtainwalls, corridors and party walls. This sealant also is used as a lap joint and perimeter sealant for polyethylene vapor barriers over fiberglass batt or other insulations and may be used in contact with polystyrene.

• The application of Tremco Acoustical/Curtainwall Sealant greatly increases the Sound Transmission Class (STC value) of a system and reduces the decibel level when one or more beads are applied to a joint.
• Sealant does not cure or dry by design.
• It is a non-skinning, non-hardening formula that will remain viscous and tacky to further aid in decreasing sound transmission.
