  • Is this product recommended for exterior wall installation in cold Minnesota weather? If not, do you have a product that is?
    Also, what is maximum wall thickness this product can accommodate? 12" to 14"?

    Hello Gil Fleischhacker,
    • Although some customers still use these products for outdoor, the manufacturer voids the warranty if you do. We do not have any outdoor compatible products.
