Does anyone know of a source for clear cross-linked polyethylene vapor barrier? There was a Bob Vila episode where this product was stapled over the wall studs and cellulose insulation was blown in. It was clear so you could see the insulation packed in the wall cavity. I watched the episode again and the product is labeled 'Good News', however, I can't find it or any equivelant thus far. I live in Seattle, WA but any source is welcome. Thanks.
