Is Castleblock™ harmful to the environment?
Castleblock™ is highly beneficial to the environment. By incorporating both the means of construction and insulation, building with Castleblock™ eliminates most waste. And because all Castleblock™ structures are insulated, energy use in finished structures is reduced substantially. Finally, the manufacturing process is neither harmful to the environment nor to the people who make Castleblock™ – CFC’s, HCFC’s or other toxic substances are not used in its manufacture.
