Styrofoam board insulation, typically made from expanded polystyrene (EPS) or extruded polystyrene (XPS), is generally considered safe for use inside homes when properly installed. It is non-toxic and does not emit harmful fumes under normal conditions. However, it is flammable and should be protected with appropriate materials, especially in areas close to heat sources. Additionally, it’s important to ensure that it is not exposed to moisture, as this can lead to mold growth or degradation of the material.
Yes, DOW blue board, which refers to extruded polystyrene insulation, can be used under concrete floors. It provides thermal insulation and can help prevent heat loss, making it suitable for use in slab-on-grade construction. However, it’s essential to ensure proper installation and consider any local building codes or requirements for insulation in flooring applications.
