I am having a house built in PA on a hill top that is fairly windy. The builder uses only rigid foam sheathing (1/2"TUFF-R is the brand they use) with metal straps for bracing. When I suggested interest in using a solid sheathing instead to make the house more solid they basically said I was being rediculous and that using the tuff-r would prevent the vinyl siding from warping. This is most likely the house I will stay in for a long time so I want to do it right. I haven't committed to this builder yet and am considering going with some one else that will cosider solid sheathing. I hate seeing warped vinyl siding. Any opions on this are appreciated.
