Hello Greg,
At our office located in Galveston Texas we design structures in compliance with the 2006 IRC and 2006 IBC (multifamily and commercial) with the Texas Revisions. Compliance with these codes is essential to being able to get an insurance certificate (WPI-8). WPI-8 certification is required for:
structural
roofs
siding
windows
exterior doors (including garage doors)
and now fences.
The Texas Department of Insurance (TDI) requires each of these items to receive a WPI-8. Only engineers appointed by the TDI are allowed to perform these inspections. I am one of these; however, the TDI list all appointed engineers on their web site.
Based upon structural testing done in my lab in Austin (ASTM E72, and ASTM E1886) SIP's perform quite well in hurricane wind zones and are far superior to wood frame construction and cost less that wood frame construction that has sufficient "hurricane ties" to comply with the IRC. TDI currently has no SIP product evaluations and they do not have a specific product acceptance criteria for SIPs. I have worked with one of my former graduate school classmates at TDI (Paul Bove) do develop an acceptance criteria for SIP data evaluation. We have agreed that until TDI can develop their on acceptance criteria TDI would accept the same acceptance criteria used by the International Code Council (ICC). The Acceptance Criteria for ICC is is called AC04 and is available free on line at the ICC web site.
If you have any specific questions please feel free to contact me off line.
