Spray Foam in Older Buildings

Efficient Foam Insulation Inc. keeps warm air inside during winter and prevents hot air from entering during summer, reducing heating and cooling costs. Many older buildings don’t have sufficient insulation, and that can create drafty rooms and costly energy bills. However, addressing these issues can be tricky in old houses, as moisture management and ventilation are critical. This article explores options for achieving an efficient and comfortable living space without compromising the integrity of the building’s structure.

Spray Foam in Older Buildings

Spray foam is a tried-and-true approach to insulating new construction, as it seals air leaks and fills gaps and odd-shaped spaces with minimal disruption to the wall structure. It’s also highly effective, providing an R-value of 6.5 to 7 per inch. However, it’s not always an option for insulating existing walls because of the need to access the entire wall cavity.

Additionally, if the walls are previously insulated with traditional fiberglass, it’s important to remove that insulation prior to applying spray foam as it will trap moisture and prevent wood from drying naturally, creating mold, rot, and rodent infestation. Moist fiberglass can also develop a musty smell and attract insects, which will further compromise the integrity of the home or business.

Spray foam is not a permanent solution, but can be used to supplement other types of insulation and save money on energy costs. The process is quick and efficient, minimizing disruption to the homeowner or business owner, and can be performed in stages. Because spray foam chemicals are toxic prior to hardening, occupants should stay away from the area for about 24 hours following application.
