Air Barrier Considerations
1.607.227.1378
Builders of spray foam insulated homes eliminate most air/vapor retarder installation and moisture problems. spray foam provides an effective, continuous air barrier to both outside humid air in cooling climates and inside humid air in heating climates.
No building wrap or additional vapor protection is required except in the most severe Northern climates or situations where there is a continuous, year round vapor drive in one direction, such as encountered in indoor swimming pool enclosures. In such situations, a vapor retarder paint is recommended. Please note, too, that spray foam is available in both open and closed-cell varieties to accommodate different requirements especially when it comes to moisture-laden environments.
Spray foam is also the perfect solution for sealing cavities at joist ends, as these areas have a high potential for air leakage.
Because of it's low air permeance, spray foam is not infiltrated by moisture-laden air. When applied to a vapor permeable surface, condensation will not occur within it. Please email us for more information. We have reprints of many technical articles available.
