Composite Fire Door Meets Local Standards As local authorities across the country are adopting the 2000 International Building Code and requiring a 20-minute positive pressure rated door, Therma-Tru says it is providing home builders and remodelers with an affordable and attractive solution to meeting the new standard. Therma-Tru Doors says it is manufacturing the industry's only fiberglass entry door that meets the standard without intumescent jambs or weather stripping applied to the jambs. The door achieves its fire resistance though a patented core material, according to Therma-Tru. Therma-Tru is a member of the National Council of the Housing Industry — the Supplier 100 of NAHB. The door is available in a complete product line: - Fiber-Classic® grained or Smooth-Star® smooth finishes are offered in three-foot and two-foot, eight-inch widths and flush, four-panel and six-panel styling. Therma-Tru's standard compression weather strip — which is included with any of its Split Jamb or Expandable Plus steel frames, or available separately — is an “H” rated product, making it the perfect accessory for 20-minute rated positive pressure installations.
- Similar sizes and styles of Benchmark wood-grain or smooth-finish fiberglass doors are also available.
Therma-Tru began distributing the doors during the final quarter of last year. Headquartered in Maumee, OH, and founded in 1962, Therma-Tru was a pioneer in the fiberglass entry door industry and today offers a complete portfolio of entry and patio door system solutions, including decorative glass doorlites, sidelites and transoms, and door components.
