What type of foam is used for stucco?
Polystrene. Most of the foam boards used with stucco in the one coat system are made out of polystyrene, which is moisture repellent and relatively rigid in terms of its structure. Polystrene is similar to polystyrene foam, but is harder and more durable. It is also used extensively in packing and model making.
How is foam molded?
The structural foam molding process requires an inert gas (such as nitrogen) to be mixed with the chosen plastic material inside an extruder barrel. This mixture is then injected into a mold using less pressure than what is common in injection molding. Once injected, the gas expands, filling the mold cavity.
Can you stucco over foam?
Install stucco as an exterior wall cladding over rigid foam insulation with proper preparation to provide water management as well as a sound substrate for the stucco. Flash all windows, doors, and other penetrations to the water control layer prior to installing the insulation.

What is better EIFS or stucco?
The fiberglass layer provides more durability, even against hard blows from weather. EIFS is notably lighter than traditional stucco, however. It is 80-percent less heavy than stucco, but it has a higher R-value, coming in between 4 and 5.6, which is notably higher than the 0.20 R-value of regular stucco.
