Retrofit your home while protecting the integrity of your existing walls. The GreenFiber Sidewall Nozzle allows you to easily install loose-fill insulation in sidewall cavities—the second major area of energy loss in most homes. This one-piece attachment makes the recommended two-hole, double-blow technique simple and easy to perform. Available by special order only.
