Insulation serves two primary functions: it minimizes heat transfer between spaces and enhances soundproofing capabilities. This dual-purpose functionality helps maintain comfortable temperatures and reduce noise transmission in buildings.

Several indicators suggest inadequate insulation: inconsistent temperatures throughout your home, elevated energy costs, noticeable drafts near windows, doors, or electrical outlets, formation of ice dams on the roof during winter months, and heating or cooling systems that seem to run continuously.

R-Value is a measurement used to quantify insulation's resistance to heat flow. A higher R-Value indicates superior insulation performance, meaning it's more effective at preventing heat transfer.

In most instances, it's possible to install new insulation over existing material. This is contingent on the old insulation being dry and free from mold. Adding new insulation can significantly improve overall thermal performance.

The lifespan of insulation varies by type. Cellulose insulation typically lasts between 20 to 30 years. Spray foam insulation can remain effective for up to 30 years and, in many cases, may last for the entire lifespan of the building.
