Air Barriers In Building Construction

Our reverse wound acrylic adhesive technology combined with an stpe based backing reduces labor costs with unmatched installation speeds.

Air barriers in building construction. Some of the more common are. Houses should always be built as airtight as possible don t let anyone tell you otherwise. Exterior air barrier system using precast site cast or tilt up concrete panels figure 3 photograph 3. Air barriers in building construction the control of air movement is critical to the control of moisture and the heating and cooling of a building in all climates and is determined by basic physics.

Interior air barrier system using gypsum. As a result they help prevent air. Experience the waves of acrylic adhesive. The job of a vapour barrier is to prevent vapour diffusion and the job of an air barrier is to stop air leakage through differences in air pressure between inside and out.

An air barrier system is an essential component of the building enclosure so that air pressure relationships within the building can be controlled building hvac systems can perform as intended and the occupants can enjoy good indoor air quality and a comfortable environment. Air barriers block random air movement through building cavities. The key elements affecting air barriers are wind stack effects and mechanical pressures.

Hvac system size can be reduced because of a reduction in the fudge factor added to cover infiltration and unknown factors resulting in reduced energy use and demand. 3m vapor permeable air barriers provide a robust solution that are easy to apply and allow your building to breathe while preventing penetration by wind or rain.
