Durashield® is a tongue-and-groove fiberglass pultruded panel comprised of a pultruded skin over a foam core. Durashield panels are designed to be used as walls, roofs, and covers.

The pultruded fiberglass skin is available in either an isophthalic polyester or vinyl ester resin. Both resin systems provide flame retardance (UL94 VO). The vinyl ester is utilized in extreme corrosive applications. A synthetic surfacing veil is incorporated into the skin to improve weathering, corrosion resistance and resistance to degradation from ultraviolet rays. Resistance to weathering can be further enhanced by the application of a polyurethane paint.

The core material is a rigid closed-cell urethane foam. The ends of the panels must be encapsulated or coated with a resin similar to the skin resin to maintain the corrosion and weather resistant qualities of the total panel.
