In Southern California's intense summer heat, a significant portion of the cooling load on your home comes directly from solar radiation absorbed through the roof and re-radiated into the attic space. A radiant barrier is a highly reflective foil material that, when installed on the underside of your attic rafters, reflects that radiant heat back upward before it can migrate down into your living space. Montebello Attic Insulation installs radiant barriers as a standalone upgrade or in combination with blown-in attic insulation for maximum summer energy savings.
Unlike traditional insulation, which slows conductive heat transfer, a radiant barrier specifically targets radiant heat — making it an ideal solution for the Montebello and greater Los Angeles area climate, where rooftop temperatures can exceed 150°F on summer afternoons. Studies have shown that properly installed radiant barriers can reduce cooling energy use by 5–10% in hot climates, and the reduction in attic temperature can also extend the life of your HVAC equipment by reducing peak demand on hot days.
Our installation team staples perforated radiant barrier foil to the rafter faces, ensuring proper airflow is maintained throughout the attic. Perforated material is chosen specifically because it allows moisture vapor to pass through, preventing condensation buildup — an important consideration in California's varied humidity conditions. The job is typically completed in a single day with no disruption to your home's interior.
