1. Fiberglass-Reinforced Plastic: "FRP Roof Decks: A Solution for Challenging Conditions" is a decent starting point for information about this type of roof deck. The article comes across as trying to promote FRP, but it still has useful information. From the November 2011 issue of Interface magazine. Available on the website of RCI, Inc.
2. Lightweight Insulating Concrete: "Lightweight Insulating Cellular Concrete: A Seamless Roof Deck Installation" by Leo A. Legatski is a good basic introduction to this material. Available on the RCI, Inc. website in the May 2000 issue of Interface magazine.
3. OSB/Plywood: Excellent article for history and comparison: "Choosing Between Oriented Strandboard and Plywood" by Paul Fisette is available on the website of the Building and Construction Technology Program at UMASS Amherst.
7. Manufacturers: See here for a list of roof decking manufacturers.
