insulating over recessed lights
spraying foam in attic spaces where recessed lights are installed poses some challenges.Spraying the foam directly on the light isn't recommended therefore there is a need for a fire safe protective cover. Many installers have come up with creative solutions but there are also off the shelf products that can solve this problem. |

We wrap all lights, IC rated or not, in Thermafiber aka Rock Wool aka Rotton Cotton aka "if you thought regular fiberglass was bad, get a load of this stuff". |

We slide a piece of rigid foam board above the light and spray it in place. If the cans are IC rated we wrap them with fiberglass. I wouldn't put any insulation material within 3" of non-IC rated cans, even roxul. |
