DURASHIELD® is a tongue-and-groove fiberglass pultruded panel comprised of a pultruded skin over a foam core. The panel provides the following features and benefits:

• Integral Insulation
• Lightweight
• Corrosion Resistant
• Low Conductivity
• High Strength
• Flame Retardant
• Transparent to Electromagnetic Emissions

Applications

DURASHIELD® panels are designed to be used as walls, roofs and covers. Typical applications are:

• Radar, Microwave, Radio and TV Antenna Enclosures
• Enclosures for Electrical Equipment
• Enclosures of Chemical Processing Operations
• Buildings for EMI Testing (Computer Testing)
• Chemical Pit Covers
• Roofs on Wet-End Pulp and Paper Manufacturing
• Modular Buildings

Process

The DURASHIELD® is a tongue-and-groove panel comprised of a fiberglass skin pultruded over a foam core. (see photo at right).

The pultruded fiberglass skin is available in either an isophthalic polyester or vinyl ester resin. Both resin systems are flame retardant (UL94 VO). Vinyl ester is utilized in more 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 foam core provides an insulation "R" factor of 7 for the 1" panel and 21 for the 3" panel.
