High Performance for Condo-Grade Noise System

Quiet Qurl® 040 is a noise control insulation mat designed to limit impact noise between floors. This resilient mat absorbs noise when sandwiched in a mass-spring-mass building design.

This mat prevents liquid moisture in lightweight concrete and gypsum concrete from passing through to the substrate, which is an essential quality for wood frame construction.



  • Multi-family construction: apartments and condominiums
  • When a resilient ceiling is installed
  • Radiant-heated flooring when pumped with lightweight concrete or gypsum
  • With hard surfaces: concrete, stone, tile, vinyl and hardwood
  • With topping layers, such as gypsum concretes, lightweight concrete, mortar beds and plywood
  • With many types of subfloors and still achieves an IIC of 50 or greater
  • Helps to achieve an STC level of 50 or greater with many types of subfloors

Features and Benefits

  • Excellent performance at reducing sound in mid and high frequencies
  • Performance in wood frame construction and 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, with a 1.5” underlayment – ASTM CE 627
