Tremco Acoustical/Curtainwall Sealant was developed for acoustical sealing of drywall/gypsum board partitions, curtainwalls, corridors and party walls.

  • Used as a lap joint and perimeter sealant for polyethylene vapour barriers over fiberglass batt or other insulations.
  • 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.
