Expancel is a powerful ally in both roof coatings and in wall coatings. The microspheres are optimal for developing highly flexible exterior coatings and cool roof coatings used on concrete and similar materials.
Solar reflectance in cool roof coatings
Compare with other fillers commonly used in cool roof coatings. You'll find that most of them are not only heavier, but also offer less protection from the sun. That´s because our microspheres are packed with powers that include high solar reflecting and thermal insulating properties. Expancel's proven track record for reflecting visible and near-infrared light, and its resilient nature, makes it a perfect ingredient for formulating an elastomeric cool roof coating with superior quality.
In warm climates, air conditioning takes the lion's share of total energy consumption, with percentages around the 70 mark in residential areas. Our tiny microspheres make it possible to reduce this number by minimizing the need for turning up the AC when it's hot. Elastomeric cool roof coatings with Expancel can bring down the external surface temperature of a building by as much as 15°C/27°F*. Not only does it help keep things cool inside, it also makes relying on energy-draining air conditioning a whole lot less. In fact, by applying an Expancel-formulated coating to the metal roof of a large, one-story commercial building, cooling energy consumption was reduced by more than 40%.
*number may vary depending on intensity of solar radiation and roof type.
The science speaks for itself. The graph above compares spectral reflectance of binders with TiO2, CaCO3 and Expancel Microspheres (). From this graph it is obvious that by replacing inorganic filler with Expancel, the hiding power as well as the total solar reflection of the coating improve. This also makes the coating appear whiter.
