Radiant Barrier Explanation
At last Saturday’s volunteer day, our awesome group of volunteers helped us install a “radiant barrier” insulation system to make our building extra energy efficient. A radiant barrier’s a layer of metalized material that you can put in the envelope of a building to strongly enhance its insulation. It comes in large rolls, similar to foil. Insulators like fiberglass or cellulose work by resisting conductive and convective heat, whereas radiant barrier works by reflecting heat. Using both heat resistors and heat reflectors will ensure the best overall insulation.
This past weekend, we installed radiant barrier material on the entire ceiling of our store – meaning that in the winter, heat will be reflected down from the ceiling to keep the store warm, and in the summer, keep heat *out*. Radiant barrier basically reflects heat back in the direction of its source, so it keeps heat that is coming from the outside out, and keeps heat coming from the inside in.
