Product Name: Treadstone ® M2 
Product Family: Treadstone ® 
Acoustic Underlayment 
Treadstone ® M2 is a versatile sound control solution 
for effective noise reduction in multi-level building 
applications. As a polypropylene-based, three- 
dimensional mesh mat, Treadstone ® M2 delivers 
reliable acoustic performance while contributing to 
sustainable building practices. This bulletin outlines 
the ways Treadstone ® M2 can support LEED 
certification efforts. 
LEED Credit Contributions 
1. Low/No VOC Contribution 
Treadstone ® M2 is manufactured from polypropylene 
synthetic monofilaments that are UV stabilized. No 
adhesives are used in the manufacturing process, 
making it a VOC-free product. 
- Material Composition: The mat’s construction 
ensures it does not emit volatile organic com 
pounds (VOCs) throughout its lifecycle, 
contributing to LEED credits in the Indoor 
Environmental Quality (EQ) category, 
specifically the Low-Emitting Materials credit. 
- Healthy Indoor Environment: Treadstone ® M2’s 
VOC-free profile helps maintain better indoor air 
quality, making it suitable for projects that meet 
stringent LEED standards for healthy living 
environments. 
2. Recycled Content 
Treadstone ® M2 features 84% post-industrial recycled 
content by weight, which enables it to contribute to 
LEED credits under the Materials and Resources 
(MR) category. 
MR Credit 4: 
Recycled Content: While LEED prioritizes 
post-consumer content, post-industrial materials 
still count toward this credit. Treadstone ® M2’s 
high recycled content supports the reduction 
of virgin material usage and waste, making it 
an environmentally conscious choice for 
projects targeting sustainability goals. 
TECHNICAL BULLETIN 
LEED Credit Opportunit ies for Treadstone ® M2 Sound Mat 
Additional Technical Features of Treadstone ® M2: 
- Compression Resistance: Offers excellent 
compression resistance with its unique U-shaped 
geometry, ensuring durability and long-term 
performance. 
- Sound Control: With 1” of underlayment, impact 
noise (IIC) can be reduced by 10 dB in wood-framed 
assemblies and 20 dB in concrete assemblies. 
- Versatile Application: It maintains its acoustic 
properties with a wide spectrum of floor coverings 
and is suitable for a variety of construction designs 
- Low Profile: At just ¼” thick, Treadstone ® M2 is an 
ideal solution for low-profile sound control. 
- UL Listed: Included in 100 floor-ceiling designs, 
enhancing its adaptability for various construction 
projects. 
Summary of LEED Credit Opportunities: 
- EQ Credit: Low-Emitting Materials – VOC-free 
construction 
- MR Credit 4: Recycled Content – 84% post-industrial 
recycled content
