Lamothe Spray Foam Insulation has announced the expansion of its residential and commercial insulation services to additional service areas. The company provides spray foam insulation services in Waltham, MA, for property owners seeking to improve thermal performance and energy efficiency in buildings.

Spray foam insulation is a building material that expands upon application to fill gaps, cracks, and cavities in walls, attics, basements, and crawl spaces. According to the U.S. Department of Energy, air leakage accounts for 25 to 40 percent of the energy used for heating and cooling in a typical residence. Properly installed insulation helps reduce this energy loss by creating an air barrier that minimizes thermal transfer between interior and exterior environments.

Energy consumption data from the U.S. Energy Information Administration indicates that space heating and cooling represent the largest portion of energy use in American homes, accounting for roughly 51 percent of total residential energy consumption. Insulation improvements are among the most common energy efficiency upgrades undertaken by homeowners. The Environmental Protection Agency estimates that homeowners can save an average of 15 percent on heating and cooling costs by air sealing their homes and adding insulation in attics, floors over crawl spaces, and accessible basement rim joists.

The insulation industry has seen steady growth in recent years, driven by building code updates, energy efficiency programs, and increased awareness of the relationship between insulation and utility costs. According to market research firm Grand View Research, the global spray foam insulation market was valued at approximately billions in 2023 and is projected to expand at a compound annual growth rate of 7.8 percent through 2030. Residential construction and renovation projects represent a significant portion of this demand.

The expansion enables the company to serve customers beyond its established service territory. Robert Lamothe, owner of Lamothe Spray Foam Insulation in Waltham, stated that the decision to extend coverage was driven by increased demand for professional insulation services in surrounding communities. "We've seen consistent interest from property owners looking for reliable insulation solutions. This expansion allows us to respond to that need while maintaining the same installation standards we've built our reputation on," Lamothe said.

Massachusetts building codes require minimum insulation R‑values that vary by climate zone and building component, following the International Energy Conservation Code with state amendments. Compliance is verified through local inspections. Proper insulation, such as spray foam, helps control air infiltration and moisture, maintaining consistent indoor humidity and reducing mold risk. Additionally, through the Mass Save® program, homeowners in Massachusetts can receive rebates covering 75‑100% of the cost of insulation and air‑sealing upgrades

Commercial property owners use insulation to lower energy costs, which can represent about 30% of total operating expenses, and to meet sustainability targets. Programs like Mass Save offer rebates for insulation upgrades that improve energy efficiency. The region’s cold winters and humid summers create demand for insulation that performs consistently, reducing heating and cooling loads.

The building envelope, walls, roofs, foundations, windows, and doors, is key to energy performance, with insulation working alongside air sealing to control heat and moisture. Installation quality is critical, as gaps or compression can reduce effectiveness, making professional installation essential.

Insulation projects start with assessing existing conditions, identifying problem areas, and selecting appropriate materials based on building age, construction type, and code requirements. The industry continues to evolve with new materials, installation techniques, and regulations, supported by ongoing contractor education and building science research to ensure effective, durable performance.
