 You may have noticed the logo for the Environmental Protection Agency’s Energy Star program attached to various appliances, electronics, office equipment, heating and cooling products — and the list goes on and on. But what exactly is Energy Star? Energy Star is a program to identify and promote energy-efficient products and buildings in order to reduce energy consumption, improve energy security, and reduce pollution. An Energy Star rating means the product has been tested and found to meet high standards for energy efficiency.
However, did you know that one such requirement for roofing products can apply to RV roofing membranes? A key feature in energy efficiency in roofing products is a factor called reflectivity. What is reflectivity? It’s the measurement of a material’s ability to reflect solar energy back into the atmosphere. It is like the expression: “Right back at you.” Light hits a surface and, instead of being absorbed, it is “reflected” back into the atmosphere. Reflectivity is measured as a percentage on a scale from 0 (hotter interior) to 100 (cooler interior). The higher the number the better, since it is reflecting more light. It’s what makes for a “cool” roof.
There are many roofing choices available nowadays for RVers, whether you are buying a new RV or replacing a roof on a current RV. There are different colors, different types (EPDM, TPO, etc.) and different textures. But for greater reflectivity, flexibility and long life, look to products like DiFlex II Polar White and its Energy Star testing performance. In order to be eligible for the EPA’s Energy Star program, our DiFlex II Polar White roofing had to have a reflectivity greater than or equal to 65 percent. Polar White’s reflectivity is a whopping 86 percent, putting it well ahead of the requirement, and designating Polar White as the kind of roofing material that can make a difference in your energy costs. It helps extend the life of your air conditioner because it runs less. And because it runs less, it also saves energy while reducing noise in the campground, something your neighbors will appreciate as well.
