Air barriers are designed to control the leakage of air into and out of a building, and a growing number of building owners, federal agencies, and green building trade groups are calling for their use. Here are 5 benefits of installing an air barrier.
1 - Improved Indoor Air Quality
Air barriers keep dust and other pollutants from entering the building. They also help keep out water vapor, which can lead to airborne diseases.
2 - Reduced Energy Consumption
Air leaking in and out of a building raises its energy consumption. It makes the air-conditioning systems, heaters, and ventilators work more. It is estimated that, in buildings with no air barriers, around 25% of excess energy is used to condition the air. With roof air barriers, the movement of air is blocked, making buildings more energy-efficient.
3 - Reduced Operating Costs
With barriers, there is no air leakage, hence air conditioning, heating, cooling, and ventilating is much easier, allowing you to replace large heating and cooling equipment with smaller models.
4 - Fire Safety
Fire and smoke spread with the movement of air. Hence, with roof air barriers, there is less of a chance that the interior of a building will catch fire or that a fire will spread quickly.
5 - Improved Durability and Lifespan of the Building
Water vapor that enters the building can condense and turn into liquid, causing mold and mildew. Mold and mildew can cause building materials to deteriorate. With an air barrier, this water vapor is prevented from entering the building in the first place.
