basic information
Variable Moisture-Permeable Air-Sealing Sheet [G.F. Barrier] This is an air-sealing sheet that regulates humidity. It is suitable for high airtightness and excels in moisture regulation. Specifications: Width 150cm × Length 30m, Thickness approximately 0.3mm ■ Adjusts humidity within walls throughout the year During high humidity conditions in summer, it allows moisture to escape from the walls to the interior, preventing summer-type internal condensation. In winter, during low humidity conditions, it prevents moisture from moving from the interior to the walls, preventing winter-type internal condensation. By preventing condensation within the walls, it protects insulation materials from deterioration due to moisture, maintaining insulation performance and enhancing airtightness. ■ Good workability The sheet is flexible, strong in tension, and made of easy-to-handle material. Its translucency allows for easy confirmation of the position of wooden structures and insulation materials, enabling simple and quick installation. When used in current high insulation and high airtightness homes, it prevents deterioration of the structural and insulation performance, maintaining an energy-efficient and comfortable environment.

Applications/Examples of results
Throughout the year, it controls the humidity inside the walls and constantly promotes dryness. The deterioration of building materials due to moisture not only leads to the occurrence of pests and mold but also threatens seismic resistance and health. Additionally, the deterioration of insulation materials compromises airtightness and thermal insulation, so by using variable humidity control airtight sheets, you can enhance airtightness and improve the energy efficiency and durability of the house.
