Supportive Government Regulations

The U.S. government has been proactive in promoting energy-efficient building practices through various incentives. According to the article published by the U. S Department of Treasury on 19 July 2024, President Biden’s Investing in America initiative introduced significant opportunities for American families to reduce energy expenses through home upgrades, improved insulation, and energy-efficient renovations. This initiative is supported by the historic Inflation Reduction Act (IRA), which includes an $8.8 Billion allocation to the U.S. Department of Energy’s (DOE) Home Energy Rebate programs. Moreover, the Home Efficiency Rebates (HOMES) program offers support to homeowners and renters for comprehensive energy-saving renovations, while the Home Electrification and Appliances Rebates (HEAR) program assists in adopting energy-efficient solutions, including the transition to electric appliances. These supportive regulations are driving increased adoption of energy-efficient insulation products, further boosting United States insulation market demands.

Technological Advancements

Recent developments in insulation technologies are creating a huge impact on the U.S. insulation market. Aerogels, which are lightweight and have the capability to resist heat transfer very effectively, are opening up new dimensions of thermal performance. Moreover, they offer excellent insulation without adding bulk to buildings. For instance, a Maryland-based small business, Liatris, Inc., has demonstrated a “super-insulation” product made using silica aerogels dried in a matrix with reinforced fiber. Funded by the U.S. National Science Foundation (NSF), company’s aerogel-fiber composite delivers two times the R-value per inch of foam insulation and can be manufactured using existing capital equipment and processes for high-volume production.
