Icynene is not your typical insulation. In fact, nothing at Sheldon Crossing is very typical which is why we stand out and stand above other housing communities. Simply stated, our advanced construction techniques are "state of the art." Icynene is a low density soft foam insulation, which is sprayed into/onto walls, underside of roofs and ceilings. It's sprayed on as a liquid and expands to 100 times it's volume in seconds to create a superior insulation and air barrier. Every crevice, crack, electric box, duct and exterior penetration is sealed to reduce energy-robbing random air leakage. The product is healthier, quieter and more energy efficient. In addition, Icynene delivers up to 50% energy savings versus traditional insulation.
