Why Your Tatami Mat Might Be Ruining Your Home’s Energy (And How to Fix It) Tatami mats—those traditional, engraved straw mats that have graced Japanese homes for centuries—offer warmth, texture, and timeless beauty. However, beyond their aesthetic charm, tatami mats can subtly impact your home’s energy efficiency and indoor environment in ways many homeowners overlook. If your tatami mat is contributing to hidden energy loss, discomfort, or even poor air quality, it might be time to reconsider its role in your space. ### The Hidden Energy Drain of Tatami Mats At first glance, tatami mats appear eco-friendly and insulating—but beneath their natural surface lies a hidden challenge. While tatami does offer some thermal insulation due to its layered composition (straw core, rush covers, —but the mat itself is not as efficient as modern insulation materials), poor installation, aging, or moisture exposure can drastically reduce its insulating performance.
