Spray foam insulation works by reducing the transfer of heat between your home’s interior and the outside environment. Since warm air rises, it tends to escape through the roof in winter, while in summer, the attic absorbs heat that seeps into your living spaces. Insulation acts as a thermal barrier that slows this process.

When installed properly, insulation traps air within its fibers or foam cells, limiting the flow of heat. This creates a stable indoor temperature and reduces the need for constant heating or cooling.

Understanding Insulation Performance

The effectiveness of insulation depends on its R-value, which measures thermal resistance. The higher the R-value, the better the insulation performs. Factors like material type, thickness, and installation quality all influence performance.

Spray foam offers excellent air sealing, while fiberglass and cellulose provide reliable coverage at lower costs. Together with proper ventilation and air sealing, attic insulation ensures your home remains energy-efficient, comfortable, and cost-effective throughout the year.
