"Winter is moisture-proof, summer is moisture-permeable." It is a special airtight sheet that maintains airtightness throughout the year while allowing permeability to change according to the humidity conditions within the wall.
■Winter moisture-proofing, summer moisture-permeability While ensuring airtightness (preventing air passage), this smart vapor barrier functions like a regular moisture-proof airtight sheet in winter by not allowing moisture to pass through, and in summer, when the interior of the wall becomes hot and humid, it allows moisture to pass through, maintaining a good condition inside the wall throughout the year. In summer, moisture tends to move towards the indoor side due to the temperature gradient, but if a regular moisture-proof airtight sheet (PE sheet) is installed, the humidity between the insulation and the PE sheet may become extremely high. Particularly, right after construction, the structural elements and moisture released from the foundation concrete are significant, leading to increased humidity inside the wall and further raising the risk.

basic information
VCL Smart® is a variable permeability and airtight sheet. It maintains airtightness at all times while having moisture-proof properties equivalent to that of a moisture-proof sheet in winter, and exhibits moisture permeability like a breathable waterproof sheet in summer, thereby suppressing condensation and mold within wall structures. It can be installed using the same methods as regular moisture-proof airtight sheets. For more details, please refer to the catalog.
