Monarfloor® Bridgestop® System

Acoustic Isolation System for Party Walls on Raft Foundations or a Continual Slab 

Monarfloor® Bridgestop® isolates both masonry leafs from each other, preventing an acoustic bridge by the collection of mortar at the base of the cavity. Monarfloor® Bridgestop® also isolates the party walls from the concrete sub-floor, reducing acoustic flanking, and improving the damping.

Where used with a gas or radon barrier, Monarfloor® Bridgestop® will ensure the integrity of the barrier from possible damage from mortar droppings.
