Condominium Project

AireBarrier brings new continuous insulation technology to the concept of dealing with air leakage in bricks. For this retrofit project, the user needed not only an air barrier for bricks, but also an air barrier adhesion that would bond the wall to the new framework. For this particular project, it was estimated that because AireBarrier had a 350 p.s.i. strength that it could create continuity on the wall. This would bring an end to the air leakage which existed through the wall which was causing tremendous damage to the interior walls. This is when the customer contacted Sealant Technologies, Inc for assistance. 

Introduction

Brick walls are sturdy structures that are not only functional in weight support, but ruggedly aesthetic. Brick walls can be found inside a residential dwelling, separating two rooms or as an exterior facade. However, brick is porous and is not easily sealed. Moisture can easily seep into a building through a brick. To prevent moisture, which can lead to mold and mildew growth, you'll have find a way to seal air in order to stop the air transfer which is what a good air barrier will do.

This was an unusual project in the sense that due to poor construction in 2004, these stairwells were built without any support from the framework and were for the most part, free flowing. Because AireBarrier uses high density polyurethane, the adhesion capabilities allows this air barrier to cover the entire wall, no matter what the substrate is and to provide a continuous and seemless seal. This not only provides strength, but also an air barrier adhesion that will stop intrusion of the wind and elements.

Creating A Continuous Wall

Air barriers are systems of materials designed and constructed to control airflow between a conditioned space and an unconditioned space. The air barrier system is the primary air enclosure boundary that separates indoor (conditioned) air and outdoor (unconditioned) air. In multi-unit/townhouse/apartment construction the air barrier system also separates the conditioned air from any given unit and adjacent units. The high density air barrier also typically define the location of the pressure boundary of the building enclosure.

Bonding Brick & Metal

Air barriers are intended to resist the air pressure differences that act on them. Rigid materials such as gypsum board, exterior sheathing materials like plywood or OSB, and supported flexible barriers are typically effective air barrier systems if joints and seams are sealed. Spray foam systems can also act as effective air barrier systems either externally applied over structural elements or internally applied within cavity systems.

Air barrier systems keep outside air out of the building enclosure or inside air out of the building enclosure depending on climate or configuration. Sometimes, air barrier systems do both. Air barrier systems can be located anywhere in the building enclosure – at the exterior surface, the interior surface, or at any location in between. In cold climates, interior air barrier systems control the exfiltration of interior, often moisture-laden air. Whereas exterior air barrier systems control the infiltration of exterior air and prevent wind-washing through cavity insulation systems.

Testimonial

The significant advantage of exterior air barrier systems is the ease of installation and the lack of detailing issues related to intersecting partition walls and service penetrations. An additional advantage of exterior air barrier systems is the control of wind-washing that an exterior air seal provides with insulted cavity frame assemblies

Summit Builders Testimonial

The significant disadvantage of exterior air barrier systems is their inability to control the entry of air-transported moisture into insulated cavities from the interior. As a result most exterior air barrier systems are insulated on their exterior side with rigid or semi-rigid insulations that are not sensitive to wind-washing.
