Quiet Qurl^® 60/040 MC is a nominal 0.375 inch, random filament, cuspated geometric patterned 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. With all the moisture issues in construction today, Quiet Qurl^® 60/040 MC prevents liquid moisture in lightweight concrete and gypsum concrete from passing through to the substrate – an essential quality for wood frame construction. Quiet Qurl^® 60/040 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.

Applications   • Multi-Family Construction: Apartments and Condominiums • 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) and still achieve an IIC of 50 or greater • To help achieve an STC level of 50 or greater with many types of subfloors 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. • Passes The Robinson Wheel Test with a light commercial rating with a 1.0”    FIRM-FILL® underlayment - ASTM E 1007.
