Durisol is the original ICF (Insulated Concrete Form) made from a proprietary cement-bonded wood fiber material. It is composed of specially graded recycled waste wood (100 percent clean, natural softwood lumber), that bonded together with Portland cement.
Hardened Durisol is lightweight, porous and very durable. It does not rot nor decay. It is vermin, termite and insect proof and does not support fungus growth. It is environmentally safe, does not contain nor emit any toxic elements, and is fully recyclable. It contains no plastic, foams or polystyrenes. Our latest product line provides thermal performance of up to R-28+ (steady state whole wall R-value). The Durisol wall forming system is a straight-forward method of building a reinforced concrete wall with built-in thermal, acoustical and fire protection. The wall forms are interlocking modular units that are dry-stacked (without mortar) and filled with concrete and reinforcing steel.
