York was established in 1933 and is the original innovator in the field of through-wall flashings. York also carries Sealants that work for commercial and residential projects. Sealants are a critical part of creating a flashing system. Compatibility with your flashing materials and the products that they are in contact with in the cavity wall is critical.
