Vapor Barrier Foil

Introducing a vapor barrier designed to counter both condensation and evaporation. This anti-corrosive vapor barrier sheet acts as a shield, protecting materials in the building envelope from moisture damage.

Constructed from two sheets of pure aluminum with an integrated mesh for mechanical reinforcement, it not only extends the lifespan of consumable products but also enhances the overall comfort within the building space.
