Each door in Masonite’s Lemieux Torrefied Collection is put through a protective torrefaction process — which means that the wood is heated over time, making it highly resistant to heat, cold, and moisture. The company says the doors can be safely installed without a roof overhang or in direct sunlight. A full range of sizes, species, and designs is available, with varying prices; a two-panel torrefied poplar door costs about $1,075 as a prehung unit.
