We spray Urethane foam for insulation, for moisture control, or for structure. Spray Foam is available in densities ranging from 1.8 pounds per cubic foot up to about 40 pounds per cubic foot. At 1.8 it is like Styrofoam or the foil faced urethane found at a building supply store. At 40 pounds it is like a rock. In various densities in between it can be anything necessary to meet the structural capability required by the task.  It can be used to make surfaces that need to be walked on in a theater set, be used to cast “wood” trim, or a huge variety of other applications.

Hard Coats are like foams that don’t foam, and they can range from fully rigid to very flexible. They are also available in various fire-rated versions including full Class 1 (UL E-84) versions. Hard coats are used to protect carved foam objects. They can be sprayed over Styrofoam or urethane foam to create a hard, fire rated finish, and can be sprayed either smooth and glossy or textured with a variety of patterns. Hard coats can be sprayed in molds to reproduce any variety of surfaces. This hard skin can then be be backed with foam to produce solid parts, hollow parts, or to integrate molded surfaces with an underlying armature.

EARTHANE is our own, water-“blown” urethane foam product. In place of chemical blowing agents like Freon and other highly reactive materials, EARTHANE uses water to make it turn from a liquid to a foam. The resin component is sugar based and a solid step in the direction of plastics made from renewable resources. EARTHANE is spray applied for current construction applications and for some theater, display and other applications. In our shop, we use EARTHANE to cast objects, composite cores, provide structural support and a variety of other applications. Earthane can be formulated for spray or poured application in a variety of densities from about 2 pounds per cubic foot to about 50 pounds per cubic foot. Properties vary from a rigid foam insulation to a structural foam that can be machined with metal working tools.
