How did the Fiberglass Segment Dominate the North America Building Thermal Insulation Market in 2024
The fiberglass segment held the largest share of the market in 2024, due to factors such as cost-effectiveness, easy installation, and greater availability. Moreover, the major building firms have been actively seen in preferring these fiberglass batts and rolls for construction in recent years. Also, by having excellent fire resistance and greater thermal performance, the fiberglass segment is set to create a competitive advantage in production spaces.
The polyurethane segment is expected to grow at a notable rate during the predicted timeframe, consistent with its characteristics, such as the greater thermal efficiency and ability to provide air-tight sealing. Moreover, by reducing the heat loss more efficiently, the polyurethane may remain in enhanced brand positioning and product offerings in the coming years.
Why does the Batts and Rolls Segment Dominate the North America Building Thermal Insulation Market?
The batts and rolls segment held the largest share of the market in 2024, because they are the most affordable and commonly used form in residential construction. They can be easily cut to fit walls, floors, and ceilings, making them popular with contractors and DIY homeowners. Fiberglass batts are widely available at local hardware stores, which increases accessibility.
The spray foam segment is expected to grow at a notable rate due to having superior energy-saving properties as compared to batts and rolls. Moreover, the spray foam has the capacity to fill minor gaps and cracks, spreading the market potential in the current period. This makes buildings more efficient and lowers utility bills. Spray foam also adds structural strength and resists moisture, preventing mold issues.
How did the Wall Segment Dominate the North America Building Thermal Insulation Market in 2024?
The wall segment dominated the market with the largest share in 2024 because walls are the largest surface area of most buildings and the primary source of heat loss. Insulating walls provides the greatest impact on energy efficiency, making it a priority in both residential and commercial construction. Materials like fiberglass batts are specifically designed for wall cavities, making them convenient and cost-effective.
The roof segment is expected to grow at a significant rate because heat rises, and poorly insulated roofs cause major energy losses in buildings. With climate change causing hotter summers and colder winters, roofs are now seen as critical for energy savings. Advanced insulation materials like spray foam and polyurethane are increasingly used in roofing applications to improve thermal resistance and prevent leaks.
Can insulation Really Cut Down Energy Bills This Much?
The residential segment held the largest share of the market in 2024 because of massive housing demand and frequent retrofitting of older homes in the U.S. Families want lower energy bills, and insulation is one of the easiest upgrades to achieve that. Government programs and tax credits also encourage homeowners to insulate attics, walls, and basements. Fiberglass batts and rolls are widely used in residential projects, keeping costs affordable while improving comfort.
The commercial segment is expected to grow at a notable rate during the predicted timeframe because large office buildings, schools, hospitals, and shopping centers consume far more energy than homes. Rising energy costs and stricter building codes push businesses to invest heavily in high-performance insulation. Green building certifications like LEED also drive demand for advanced insulation in commercial projects.
United States Building Thermal Insulation Market Trends
The United States dominated the North America building thermal insulation market in 2024, akin to the advanced construction infrastructure and sustainability implementation. Moreover, the stricter energy efficiency standards are positioning industry for long-term expansion. Also, consumers are accepting the standards of thermal insulation that undergo the regulation of firms like LEED and federal energy codes in the current period. Moreover, the heavy push of the infrastructure updation is actively strengthening the foundation for future sector growth.
