Dynofoam is a rigid, closed-cell, flame-retardant polyurethane foam with a density rating of 10 pounds per square foot. It exhibits a high strength-to-weight ratio due to its cellular structure and cross-linked resin.
Dynofoam will not swell, crack, or split on exposure to water and is resistant to U.V. exposure. Dynofoam combined with a high-tech polyurethane paint finish is the ultimate exterior foam letter product. It has the appearance of a cast metal letter, yet is lighter in weight and much more economical.
HowMac stands behind their high-tech Dynofoam product with a life time warranty.
