Quiet Qurl^® 55/025 MC is a nominal 0.25 inch, random filament, corrugated, “U” Groove core sound control mat designed to limit impact noise between floors. It is produced from an extruded polymer matrix of tangled monofilaments. The monofilaments are heat welded at the junctions to form a resilient structure that absorbs noise when sandwiched in a ‘Mass/Spring/Mass’ building design. Designed for critical applications where gypsum concrete will be utilized Quiet Qurl^® 55/025 MC prevents liquid moisture from passing through to the substrate – an essential quality for wood frame construction. Quiet Qurl^® 55/025 MC, a CLASS A fire rated product, allows moisture to continue to evaporate from the bottom side of the topping pour but prevents trapped moisture since it continues to allow moisture vapor to pass through. When used in conjunction with 1.0 inch (2.54 cm) FIRM-FILL® 3310 Gypsum Concrete, the combined system can achieve a “LIGHT COMMERCIAL” rating from the Tile Council of America.

Applications • Multi-Family Construction: Apartments and Condominiums • Retrofit applications with ceiling assemblies left exposed topping won’t pour    through the ceiling • Radiant heated flooring when pumped with light weight concrete or gypsum • With Hard Surfaces: Concrete, stone, tile, vinyl and hardwood • With Topping Layers such as: FIRM-FILL® Gypsum Concretes, Lightweight    Concrete, Mortar Beds and Plywood • With many types of subfloors (with or without ceiling assemblies, many types    of wood structural joists and ceilings) Features & Benefits   • Excellent performance at reducing sound in low and high frequencies. • Performance in wood frame construction and in concrete structures. • Minimal deflection and no creep or long term degradation. • Provides a thin profile for tight construction assemblies. • Lightweight and easy to handle.
