Roof Coating Product

Elastomeric Coatings are liquid applied, fully adhered, "rubber-like" protective membranes. They can be applied as part of a roof or wall system during the construction stage, in retrofit or as a maintenance application. Both primer and finish coats can be spray applied to ensure quick application, consistent appearance and a durable finish.

Reduction of heat saves a roof by limiting thermal shock and extending its useful life. Elastomeric Coatings are very versatile and can be used on virtually any clean, dry and mechanically sound substrate including built-up, modified bitumen, single-ply, metal, asphalt, polyurethane foam or concrete roofs as seen below.

Energy Efficiency

• High Reflectivity
• High Emissivity

Cool roof coatings reflect 70% to 90% of the sun's energy when newly installed. Most of the energy is radiated away. Conventional roofing materials have reflectivity of 5% to 25%, meaning they absorb 75% to 95% of the sun's energy. A typical “white” capsheet roof only reflects 25% of the sun's energy. The absorbed energy is transferred to the building.

Emissivity is the ability to radiate away absorbed heat. Most cool roof coatings emit 90% or more. Even though aluminum coated roofs are highly reflective they are not considered a cool roof because they only emit 50% to 60% of the absorbed energy.

A conventional roof can get up to 180º on hot sunny summer days. A cool roof coating keeps the roof at just 10º-15º above the air temperature. This means a cool roof can be 80º to 90º cooler than a conventional roof.

Even at relatively cool temperatures there is a big difference in how much heat is absorbed. The chart shown below, done by Lawrence Berkeley National Laboratory, demonstrates how different roofing materials are affected on a sunny day when the air temperature was only 55º.

Cooler roof surfaces means less heat is transferred into the building. If you air condition a building one will save money on cooling energy. How much savings will depend on many factors including roof insulation, cooling system equipment and other variables. In the right situation, a reflective roof can bring cooling savings of up to 50%, with a reduction in peak cooling demand of 10% to 15%.
