Why Choose Perforated Products?
Over 75% of applications will use a perforated product. WarehouseFoil’s perforations are still small enough that even the perforated foil acts as an air barrier. The perforations are too small for liquid to pass through, but they do allow gas (water vapor) to pass. This means the building doesn’t hold moisture against the walls or ceiling and it can dry properly. For more info, check out this page on our site: Perforated vs. Solid Foil, Which One Do I Need?

Why Choose Solid Products?
If you’re in an extremely cold climate or looking specifically for a vapor barrier, then the solid products are for you. When using these products you should make sure the areas are sealed air tight since these products do not breathe and will not be able to dry out any moist air that gets between them.
