壁内結露を防ぐ「呼吸する壁」の秘密とは？先進ドイツのシュタイコゼル徹底解説・第二弾

About the functionality of Steikozel, a "breathable insulation" Wood fiber insulation is characterized by its high moisture absorption and release properties, making it less susceptible to condensation. Mold and wood-rot fungi are dangerous when relative humidity exceeds 80% for long periods of time. Wood fiber insulation can retain approximately 4-5 liters of water vapor per cubic meter, reducing the risk of condensation. In a condensation simulation using WUFI, depending on the wall's internal structure, relative humidity can exceed 80%, but wood fiber insulation's moisture absorption reduces the relative humidity to the 70% range. To take advantage of this moisture absorption and release and moisture retention properties, no "airtight sheet" is used. This fundamentally prevents the "summer condensation" that has become a recent problem. In Japan's rapidly changing climate, with its high temperatures and humidity, "high airtightness" fails. The three key features for building a comfortable home are "high insulation," "high heat storage," and "medium airtightness"! #Steikozel #InnerWallCondensation #SummerCondensation #CapillaryPhenomenon #WUFI #CypressDurability #HoryuJiTemple #MediumAirtightness ■■RelatedVideos■■ Steikozel Explained: Part 1 Aren't you just looking at thermal conductivity?
