Chris has several decades of steel SIP building experience, and has been a big help for me getting steel SIP building started in California. I can assure everyone he knows his game quite well. Currently, I am building a 4,300 SF Custom Mexican Hacienda out of steel SIPs near Joshua Tree National monument in California. Seismic zone "E", and in a high risk wild fire zone, harshest CA climate zone. Before I choose steel SIPs I researched several other types including Mgo SIPs, OSB, and other varieties. Steel SIPs are made by several companies in the US including permatherm, and this company does have structural and fire test reports. I have read all of them. I can assure everyone that these panels are hardly a "fad", rather they have been around for a long time, and are the future in my view. They accomplish a lighter, simpler load bearing structure, leading to lighter less costly foundations, less crane time, easier connections, and less and cheaper skilled labor. You can also get them up to 25 feet + long, which 2 men can tilt up with a cable on top and a guide below. You can quickly enclose a 2-3 story building. I have not experienced any issues with finishes. Stucco, wood siding over batons (1x3 rain screen) As far as the Caribbean- If you had done some homework, you'd know that it's really not all shanties for poor people. The fact that they have used these panels for housing projects and even schools, fire houses, and medical offices, the Curacao Airport should tell you something - Logistics, tools & equipment, and skilled labor are limited depending on where you are. You need something that will work and makes practical and financial sense. So if anything, it should tell you why they choose steel SIPs over other types.
