Rice hulls

They will take on moisture and swell. That will take a toll on the material.

I built a cover for the skimmer of an ingrown pool some dozen or so years ago? using that sawdust? and plastic? decking material.? It? did take on moisture and? started shedding material from the surface and eventually? failed completely.? It took more than a decade.? Maybe they will get more life from rice hulls??

Just catching up on this old house. Last week’s episode showed this PVC with rice hull product which they are using for trim. Especially interesting is that one can take a wedge out (similar to Rockler miter fold) from the middle of a long trim board and fold it 90 degrees (some heat required) to make a seamless corner trim board.

Has anyone used this product? Comes in sheets as well as boards. Paintable and stainable (apparently to look like wood).

Last time I got excited about a new siding product rated for ground contact made out of waste ash was short lived. At?$80 a board (5 yrs ago), it is definitely out of my price range.?

PS, they never mentioned the product name on the show. A search brought up ACRE which match the description. Not sure if there are other manufacturers supplying the same product.
