Air barrier

(redirected from Air barriers)

Air barrier

Building assembly components that work as a system to restrict air flow through the building envelope. Air barriers may or may not act as a vapor barrier. The air barrier can be on the exterior of the assembly, the interior, or both.

The article reinforced the distinction between vapor retarders and air barriers. It also recognized that the positive impact of airtightness is still not widely appreciated within the construction industry.
With a thorough understanding of air barriers, a qualified design team should have no trouble achieving 0.40 cfm/[ft.sup.2] (2.03 L/s x [m.sup.2]) with any of the commonly used air barrier systems.

CPA Engineered Solutions reports it is a total air solutions company providing engineered solutions for compressed air generation and treatment, process drying, pneumatics and industrial automation, air knife drying systems, air energy management, Enershield air barriers, heat recovery fans and Steril-aire germicidal UVC emitters.
DOE Office of Building Technologies, tested the effectiveness of air barriers. It prepared energy simulations for three types of commercial buildings in five types of climates (Bismark, ND; Minneapolis; St.
For optimum control all models are fitted with a built-in Building Management System (BMS) interface as standard, meaning the air barriers can operate as part of an integrated energy management system for improved people comfort and control.
The movement of air and vapor into the interior of wall assemblies is controlled by two different materials: moisture barriers and air barriers. Moisture barriers simply prevent the passage of water.
Workshops will include air barriers, acrylic waterborne coatings and failure analysis.
Both closed-cell and open-cell spray polyurethane foams are excellent air barriers. Additionally, because closed-cell spray polyurethane foam resists both air movement and water vapor movement, air barriers and vapor barriers usually can be eliminated, further reducing the amount of building material needed.
This type of airflow has poor thermal transfer characteristics of energy from the hot air to the product being processed because of the laminar air barriers around the product.
