Jeff, We have used Thermo-ply on a military housing project in Southern California and have been told of it use on other military housing projects in Northern California and other states. I am not aware of any buildings which have gone through an earthquake though that used thermo-ply for the wall sheathing. As you noticed, the allowable shear is more than gypboard, but less than plywood. Since the thickness is only about 1/8 inch and roofing type nails are used for the attachment to the studs we only used it on very long walls (wall height/wall length ratio = 1/4 = 0.25). All shorter walls used plywood. The material seems rather flimsy and probably would not fair very well if you did some dynamic testing on a wall panel sheathed with thermo-ply. But, because of cost, we well most likely have to use it on any future military housing projects, especially since it has an approved shear value with an ICBO approval. Depending on the project which you are involved in, you might want to require some dynamic testing of a thermo-ply sheathed wall panel to determine how it actually performs. Michael Cochran Brian L.

I have a call into a local rep. Did any Northridge buildings use this and if so how did it perform. It has a 1991 ICBO # 1439. Maximum allowable aspect ratio is 2:1. One of the footnotes states that maximum wall height is 4 feet and it also references the conventional construction provisions of chapter 25 1988 UBC. It appears to have very limited applications. Looking at a sample, I am not surprised. Regards, Jeff Smith.
