Acoustic data is available on this product, please contact the Technical Services Department for further information.

Promat PROMASEAL® Fire Barriers are designed to be installed within openings in masonry, concrete or stud partition walls. The Promat PROMASEAL® Fire Barrier is cut to size such that a firm friction fit is achieved. Using a trowel or pallet knife, apply a layer of Promat PROMASEAL® Fire Barrier Coating to the areas in contact with the opening and also ‘butter’ onto the edges of the batt.

Where Promat PROMASEAL® Fire Barrier batts are cut to accommodate passage of services through the batt, the batt should be cut tight into the opening and tight around the service penetrations.

Promat PROMASEAL® Fire Barrier Coating must be used to point-in any service penetrations through the batt.

Services should be supported no more than 500mm from both sides of the PROMASEAL® Fire Barrier. Cables and services do not need coat back.
