AIR BARRIERS
be much more popular in northern climates of the United States and in Canada at this point.
Although barriers have become an integral part of today's masonry wall systems, careful consideration still must be taken in selecting anchoring systems that will perform well with the barrier material. The systems must also perform the No. 1 goal of properly holding the veneer in place. The growth of selecting an anchoring system based strictly on the recommendation of a barrier manufacturer, with little to no knowledge of the criteria for effectively holding a veneer in place, can be a dangerous situation for all parties involved. This is exactly why material manufacturers must work together to provide the most complete information possible for the designer and contractor. Just as important is the roll of the applicator for the proper installation of the system.
As the air barrier industry continues to grow and mature, newer issues become more prevalent, and all parties involved from the architect to the product manufacturer to the installer must have an understanding of each of their roles in developing effective continuous barrier systems. Detailing is extremely important, especially the details where the barrier ties into a roofing system and also the below-grade waterproofing, Failure to tie these systems together will result in an ineffective building envelope that does not perform its intended purpose. To be sure, growth will continue and with that will come more questions and issues that everyone must together solve. IMAS
