Lunawood Thermowood avoids chemicals in its manufacturing processes, relying solely on a treatment with high heat and steam that enhances the wood's durability. This allows for an extended lifetime and a surface that requires no finishing and less routine maintenance, regardless of climate. However, applying paints, oils, and other finishes is possible (please see HML's list of healthier finishes for recommendations). Since the processing eliminates natural resins, no resin will secrete through any applied finish or paint.

Per EPD, this product meets HML's criteria for low embodied carbon.
