Quiet Qurl® Sound Mat

The perfect solution for limiting airborne and impact noise that passes through floors and walls.

This resilient mat absorbs noise when sandwiched in a mass-spring-mass building design.

Designed for critical applications in which gypsum concrete will be utilized, Quiet Qurl prevents liquid moisture from passing through to the substrate – an essential quality for wood frame construction.

Quiet Qurl® systems are available in .125", .25", .40", & .75" thickness

Quiet Qurl: Raising the bar

Designed for use with underlayments such as gypsum concrete and lightweight conrete, the Quiet Qurl® system dramatically reduces impact and airborne noise transfer.

Frequently Asked Questions about Quiet Qurl® for Architects and Developers

Quiet Qurl® is an engineered acoustic mat placed beneath gypsum concrete to effectively mitigate sound transmission in multifamily residential and commercial structures. It’s strategically designed to meet or exceed building code acoustical requirements.

Quiet Qurl® significantly enhances the Impact Insulation Class (IIC) rating, providing a resilient isolation layer to minimize impact-related noise such as footsteps, ultimately improving occupant comfort and satisfaction.

Consider your project’s targeted sound performance levels (IIC ratings), floor assembly construction, and intended gypsum concrete thickness. Quiet Qurl® is available in four thicknesses—013 (1/8”), 025 (1/4”), 040 (3/8”), and 075 (3/4”)—to meet varying acoustical and structural needs.

Quiet Qurl® MT offers superior sound control in thinner assemblies, enabling cost-efficient designs by allowing a reduction in gypsum concrete depth without compromising acoustical performance.

Minimum pour depths are: – Quiet Qurl® 013: 3/4” – Quiet Qurl® 025 & 040: 1” – Quiet Qurl® 075: 1.5”

Quiet Qurl® systems consistently meet or exceed IIC and STC requirements set by local and national building codes, providing assurance of acoustic compliance in your project documentation and approvals.

Specify Quiet Qurl® by thickness and product type in project specifications. Products can be procured directly through our dedicated sales network or authorized distribution channels, which offer technical consultation and logistical support.

Quiet Qurl® mats ship on standardized pallets: – Quiet Qurl® 013 & 025 MT: 18 rolls per pallet – Quiet Qurl® 025 & 040 MT: 10 rolls per pallet – Quiet Qurl® 040, 075 & 075 MT: 8 rolls per pallet

Quiet Qurl® installations performed by trained contractors qualify for our comprehensive 10-year system warranty, ensuring confidence in the long-term acoustical performance and durability of your project.

Yes, Quiet Qurl® products can be combined in single truckload shipments, accommodating specific project requirements with flexibility in pallet configuration (up to 26 pallets per truckload).

Quiet Qurl® is designed to be compatible with most gypsum concrete systems, provided they meet specified minimum thicknesses and maintain a minimum compressive strength of 2000 psi.
