Safety and Sustainability by Design

Eliminating Hazards & Elevating Standards with M4 & NOCOM

One of the most pressing job site concerns today is respirable crystalline silica dust, which may be released when sanding, cutting or demolishing portland cement boards or poured concrete / gypsum toppings. Because of its long-recognized risks, OSHA places strict limits on exposure, creating not only safety concerns but added compliance costs for contractors.  M4 & NOCOM panels eliminate this risk. Third party verifications confirm our products contain no silica, no crystalline quartz, no asbestos, no formaldehyde, and no VOCs.

NOCOM & M4 Contain No Silica & No Crystalline Quartz - Backed by our International EPD Reporting Program

Verified by Third Parties

Don't just take our word for it. MPI products such as NOCOM Subfloor, M4 Underlayment & M4 Wall Sheathing are backed by third-party documentation from agencies including UL, ICC, QAI, and Intertek for fire, acoustic, durability, and health performance. In addition, our Environmental Product Declaration (EPD S-P-12112), published under the International EPD® System, provides transparent, third-party verified data on environmental impacts. This ensures that our claims are documented and comparable under the same framework used across the global construction industry.

M4 Environmental Product Declaration

Healthier by Design

• No crystalline quartz or silica dust – Eliminates a major OSHA-regulated hazard common with some portland cement boards and poured concrete or poured gypsum toppings.

• No asbestos, no formaldehyde, no VOCs – Safer for installers and better long-term indoor air quality.

• Mold and corrosion resistance – ASTM testing confirms resistance to biological growth and corrosion on steel, aluminum, and copper.

Sustainability Through Durability

• Dimensionally stable – Panels resist swelling, cracking, and shrinking under jobsite conditions.

• Longer service life – Reduced replacement cycles mean less material waste and lower environmental burden over decades.

• Dry installation – Panels install with mechanical fastening only. No curing, no temporary heating, and no added moisture in the building envelope.

Smarter, Cleaner Construction

• Lightweight panels – easier to handle and significantly lighter than poured concrete or  gypsum toppings

• No surprises on site – Factory-made panels install cleanly, avoiding cracking, shrinkage, or leveling problems common with wet pours. 

• Faster timelines – Install with standard carpentry tools and immediately move on to framing and finishes – no curing, no waiting, no wasted time. 

The Bigger Picture

True sustainability requires products that are safe for people, durable in service, and transparent in reporting. M4 / NOCOM panels meet this standard by eliminating silica and other harmful substances, extending service life, and publishing verified environmental data through a global EPD program.

Conclusion

With M4 & NOCOM panels, you’re choosing a system that is safer for installers, healthier for occupants, and verified for environmental responsibility. No silica. No quartz. No compromises. Learn more about our EPDs, tested assemblies, and certifications on our Resources page.
