Cellular PVC Panels

[rhubbell]

I am building a "larger" (6 x 12) camper. Wondering if anyone has used cellular PVC sheets for walls, floor or, roof. There are several companies you may have in your area such as Versatex, Veranda, Azek ... The material will not absorb water, i lighter than plywood, and is UV stable. Only two issues I can see is the price and expands more (10%? ) more than plywood. I know boat builders us something similar but even more expensive. I appreciate any feedback.

Watch out for expansion and contraction.

The only information I could find was about 10% greater linear coefficient of thermal expansion. Any experience with the product as to how much expansion/contraction for construction purposes?

I have used PVC dimensional lumber as drip rails and installed with SS fasteners. The boat builders use StarBoard which is quite expensive. I have used it as a sort of chair rail in food trailers. I personally dont believe that it is as solid as wood or metal, it flexes quite easily but it pays to experiment. I am still contemplating using ABS over foam for my next build.
