Insulating paint. It sounds good, and it’s a theory that’s been around since NASA conducted research in the 1980s. The basic concept — an exterior paint with effective insulating properties that could be easily applied to a house to inhibit heat loss and heat gain — could revolutionize energy efficiency and indoor comfort by eliminating the need for labor-intensive conventional insulating materials. Still, just one commercially available insulating paint that makes limited claims has yet to reach the market.
Does It Really Work?
As research continues, however, results of multiple tests to confirm the efficacy of insulating paint formulas have proven, at best, inconclusive. Only one university experiment reported positive results, achieving a 20% reduction in heat loss when the insulating formula was applied to exterior walls that received full sun exposure.
What’s The Better Option?
Unless or until more-conclusive results are confirmed, most industry experts, including those at the Department of Energy, recommend utilizing standard insulating methods and materials for optimum reduction of unwanted heat loss or heat gain. Here’s how to get maximum benefit from proven, conventional insulating methods:
-
- The attic is ground zero for heat loss and heat gain in most residential structures. In our climate zone here in Northern Ohio, current Department of Energy recommendations call for insulating the attic to a level of R-38 to R-60. If you’re installing common fiberglass batts, this means total depth should be at least 12 inches and may be as deep as 20 inches. For blown-in cellulose insulation, the recommended depth range is 10 inches to 17 inches.
- In addition to bringing attic insulation up to current standards, take steps to reduce air leakage into and out of the house. Track down cracks, gaps, and other openings that let heat escape in winter and invade during summer. Seal leaks with caulking or expandable foam. Also, check the weatherstripping around doors and windows and replace any that’s worn or missing.
