A single 200 sq. ft. bundle is $50, with a price break for quantity down to about $46 a bundle. The only improvement that I would make to this product is that it would come in white. This material is manufactered by Adams as well.
Keep up the good work dz1sfb. I'm interested in learning more about this High Performance Underlayment. What is the thickness?
Also...bundling may not be an issue if the material is cut into separate pieces. It's the folding of the long continuous foam that introduces all the curvature into the sheets.
I notice we have an Allied Building supply here in Columbus.
I'm going to take a spin down there and see if they have they stock the High Performance Underlayment product.
