Technician repairing a wall-mounted furnace ## How does a radiant barrier work? The sun heats the roof, and the underside of the roof deck radiates that heat down into the attic. A radiant barrier is a reflective foil layer stapled to the rafters or laid under the roof deck that reflects that radiant heat back and gives off little of its own, so the attic, the ceiling below it and any ducts in it stay cooler. It only works against radiant heat, so its benefit depends on how much sun the roof gets. Installer working on an attic ceiling ## Is a radiant barrier worth it in the Valley? Because it blocks radiant heat from the roof, a radiant barrier earns its keep in hot, sunny climates, and most of all where ducts and the air handler sit in the attic. The San Fernando Valley has long, sunny summers. It is worth it when: - Your AC and ducts are in the attic; if that system is also near the end of its life, see [AC installation](https://elviraoceanair.com/ac-installation-ca/). - The roof gets full afternoon sun. - Upstairs or top-floor rooms stay hot into the evening. It is less useful in a shaded house or one with no attic ducts and deep insulation already. ## Radiant barrier vs attic insulation They solve different parts of the problem. Insulation slows heat conducted through the ceiling; a radiant barrier stops radiant heat from the roof. A barrier does not replace insulation, and many attics benefit from both. See [attic insulation](https://elviraoceanair.com/attic-insulation-ca/). Attic rafters above insulation ## The installation process 1. Attic inspection: roof framing, ventilation, existing insulation and ducts. 2. Foil installed on the underside of the rafters with an air gap and the reflective side facing the open attic. 3. Attic ventilation checked so heat can leave the space. 4. Optional: insulation topped up and ducts sealed in the same visit; see [air duct replacement](https://elviraoceanair.com/air-duct-replacement-ca/). ## What customers say about Elvira Ocean Air ★★★★★ > "Sam and his team were amazing start to finish."
