Acoustic and Fire Performance. One Sealant.

Arbo XL1075 Intumescent Acoustic Silicone Sealant is a specialist product that delivers both acoustic attenuation and fire resistance in a single application — ideal for party walls, separating floors, and fire-rated partitions where both sound and fire performance are required. The intumescent formulation expands under heat to seal gaps, while the acoustic properties help reduce sound transmission through joints and penetrations.

Supplied in a 380ml cartridge.
