As if we weren’t aware enough of the potential energy crisis, delivery from the Alaska oil fields will now be reduced indefinitely. Get a grip on your heating and cooling costs, folks—this is serious! So, I think it’s a great time to look at energy efficient improvements and technologies that are coming to the rescue. The first one to catch my eye was the Durazone Roofing System from UCSC of Phoneix, Arizona. This spray polyurethane foam roof system starts by priming the roof sheathing with Solargain Primer to reduce the roof’s heat gain. Their foam insulation is then applied at a thickness of 3.5 inches, to produce an R-Value greater than 20. The final surface application is a series of elastomeric coatings, first a base and then a topcoat, for reflectivity to prevent heat gain and protection from UV rays to reduce deterioration of the surface coatings. This is cool roof technology that is aiming to support a zero energy residence. Any step we can take toward that goal is most welcome.
