A Protected Membrane Roof (PMR) system using STYROFOAM* insulation shields and protects a roof's waterproof membrane unlike a traditional roof system that does not cover the membrane. On a PMR roof, the membrane is placed beneath STYROFOAM insulation. The PMR roof protects the membrane against the most common causes of failure – sunlight, extreme heat, extreme cold, weather, and foot traffic. Traditional roofs are typically replaced every seven to 10 years. PMR roofs have lasted over 30 years. The cost savings to building owners are obvious. However, the benefits do not end there.

PMR Roofs are "Greener" Roofs
Currently, three to four percent of all waste in U.S. landfills comes from old roofs. By more than tripling the time a roof lasts, landfill space is conserved. In addition, STYROFOAM insulation resists water so well it can be reused if the roof is ever replaced, which saves even more landfill space.

PMR roofs help the environment in another way. Ever notice how large cities tend to be hotter than surrounding areas? This is because the many buildings and paved surfaces create an effect called a "heat island." PMR roofs stay cooler than black membrane surfaced roofs, helping to reduce this heat island effect.
