When it comes to manufacturing home insulation products, a few states clearly stand out in the U.S. These states not only support a strong labor force in insulation manufacturing but are also home to some of the industry’s biggest names. If you're in the building materials or home construction space—or just interested in where the backbone of energy efficiency begins—here are the top five states you should know about.
1. Ohio: The Insulation Industry’s Heartland
Ohio leads the nation in employment in the insulation manufacturing sector. With its central location, strong transportation infrastructure, and deep manufacturing roots, Ohio is a key hub for companies producing fiberglass, foam, and other insulation products. The state supports both production and innovation, making it a magnet for insulation giants and skilled labor alike.
2. Texas: Big on Manufacturing, Big on Growth
Texas isn’t just known for oil and energy—it’s also a powerhouse for insulation manufacturing. The state’s booming construction market drives high demand for insulation materials, especially in rapidly growing metro areas like Dallas, Houston, and Austin. Its business-friendly environment continues to attract major players in the industry.
3. Georgia: A Southern Stronghold for Insulation
With manufacturers like Knauf Insulation maintaining significant operations in Georgia, the state has become a strategic location for insulation production. Access to ports, a growing housing market, and a skilled workforce make Georgia an ideal base for distributing insulation products across the Southeast and beyond.
4. California: Pioneering Energy Efficiency
California's stringent energy codes and focus on green building have made it a leader in insulation innovation. The state’s high demand for energy-efficient homes drives significant local manufacturing activity. Companies like Johns Manville have a presence here, helping to meet the needs of one of the largest construction markets in the country.
5. Indiana: A Midwestern Manufacturing Powerhouse
Rounding out the list is Indiana, where insulation manufacturing plays a vital role in the state’s broader industrial economy. Indiana’s central location makes it a prime distribution point for insulation products headed to both coasts. With companies such as CertainTeed operating facilities here, Indiana continues to be a critical part of the national supply chain.
Why This Matters
The insulation manufacturing industry not only supports thousands of jobs across these states but also plays a critical role in making homes more energy-efficient and reducing carbon footprints. As demand for sustainable building materials continues to grow, these five states will remain central to supplying the U.S. with high-performance insulation products.
