#ALCHouse #ExteriorInsulationSystem #ETICS #ALC #alcmate #PassiveHouse #GermanHouse #FAKOHAUS #Insulation #MoldPrevention ALC houses are known as lightweight building materials with excellent insulation properties. However, the insulation performance of ALC is not always constant. If the ALC contains a significant amount of moisture, its thermal conductivity increases, and as a result, its actual insulation performance may decrease. In particular, ALC may have a high moisture content immediately after manufacturing and during the initial stages of construction, and it takes time to reach an equilibrium moisture content. In this video, we explain the key points you must know to understand the exterior walls of an ALC house. We cover what ALC moisture content is, why internal moisture in ALC reduces insulation performance, why judging exterior wall performance solely based on dry thermal conductivity shown in catalogs can be dangerous, and, from a building physics perspective, why FAKOHAUS views an exterior insulation system as a safer method than a single wall for ALC house exteriors. If you are a prospective homeowner planning an ALC house, it is important to understand ALC's moisture content, thermal conductivity, and the actual exterior wall system configuration, rather than simply trusting the claim that "ALC has good insulation." FAKOHAUS evaluates the performance of ALC houses not based on product names or material images, but through architectural physics analysis and proper exterior wall system design. In this Part 1, we will focus on explaining the relationship between internal moisture in ALC and its insulation performance, and in the next Part 2, we will compare the differences between single-wall ALC and exterior insulation systems.
