(1) The "Global Durability Specification" of TRU-CORE® protected trim has its own unique retention and penetration requirements that are based on a global compilation of standards and independent testing to allow the TRU-CORE® protected trim to be durable in any country.
(2) LOSP with 2 azoles and Permethrin is not standardized by the AWPA (American Wood Protection Association) for any uses. The WDMA (Window and Door Manufacturers Association) has approved several somewhat similar, but also very different, types of formulations for envelope protection to their own standards.
