Quiet Qurl^® KEENE BUILDING PRODUCTS introduces the first thin profile mat to offer luxury performance in about a quarter inch.  Quiet Qurl^® 55/025 MC MT 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 polypropylene 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. A point bonded, moisture resistant fabric is laminated to the surface so that gypsum concrete & other materials can be placed to create a floating floor. On the bottom side of the MT version, a highly compressible polyester fabric is bonded. This “muffler” almost completely compresses when installed with a 1.25” gypsum concrete floor underlayment. The compressed material adds only five hundredths of an inch to the overall assembly. Quiet Qurl^® is a CLASS A fire rated product & passes a Robinson Wheel Test with 1.25 inch (2.54 cm) of gypsum concrete with a Light Commercial Rating. The MT addition will create an additional 5 IIC points for the assembly verse standard version.  In laboratory tests, QQ 55 025 MT reduces five to 7 dB from 125 Hz to 2500 Hz.

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 an “extra Heavy Duty” rating per   ASTM CE 627.
