Muffling Technology Provides Extra Thickness for Extra Performance in Rehab Construction

Quiet Qurl® 65/075 N MT is a noise control insulation mat designed to limit impact noise between floors. A white liquid moisture-resistant fabric is laminated to the surface so that gypsum concrete and 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. The MT fabric has the ability to add 5 to 7 IIC points to a mat’s performance through diffusion of air pressure in the cavity.

The product is designed for retrofit of existing buildings in which a ceiling assembly is not utilized. In critical areas of new or retrofit construction, 65/075 N MT will provide the highest level of noise performance available on the market in any entangled net product. 

Note: In all retrofit and loft conversion applications performance should be proven with on-site field tests. No floor/ceiling performance on prior projects can replicate performance on another specific project.



  • Retrofit applications of old buildings - especially historical tax credit apartments and future condominiums
  • Loft conversions
  • When a resilient ceiling is installed
  • With hard surfaces: concrete, stone, tile, vinyl and hardwood
  • With topping layers: gypsum concretes, lightweight concrete, mortar beds and plywood
  • When ceiling construction is not an option

Features and Benefits

  • Excellent performance at reducing sound in mid and high frequencies
  • Performance in wood frame construction and in concrete structures
  • Extra resiliency for greater sound absorption
  • Thick system, in which floor height is not an issue
  • Lightweight and easy to handle
  • Zip-strip included for simple and fast installation
