We consider our process, quality controls, and warranty superior to pressure treated products and we will not allow the Industry to put us in their same category when our products are more technologically advanced and safer, while providing protection for a wide range of products beyond landscape timbers and mud sill
The other method is to staple R-19 fiberglass batts to the mud sill
(member onto which the joists are set) and drape them down to the soil, which needs to be thoroughly covered with 6-mil plastic in any case.
We need to continue embracing technologies that will protect the wood fiber strength on more than just the mud sill
so the wood fiber strength will be present when tested, instead of just allowing termites and rot to destroy the engineering values.
