Magazines do that, report emerging technologies and materials, though I haven't seen steel SIP's in JLC yet. Steel in SIP's fixes the lateral deflection issue, makes the product green but costs extra because of the price of steel. I don't get the part where they say termites won't eat it. They love it, at least the ones here do. Marc Marc, Termites might nest in the foam core of a steel skinned SIP, but it provides no food source for the insect. If they are nesting in the foam core there must be a source of moisture and wood/food near by. Some metal SIP companies can provide a foam core that is borate treated. This can eliminate nesting insects.
