Continuing Education; Senergy Commercial Wall Systems

Thanks to the Team at the Reference Library for hosting weekly Lunch and Learn seminars!

Last week we learned about Commercial Wall Systems and a more in depth look at Building Envelope Barriers.
For those who maybe aren't as familiar with this process we'll go ahead and share some of the terms and content we learned...
Sheathing is an air barrier material.  It is continuous with joins and is air tights.  It shall be durable to move with the walls.  Shall be joined in an airtight and flexible manner to adjacent materials.  i.d. must be part of the barrier.

Water Resistance on the other hand is a fluid applied barrier and must also function as water resisitve barrier.
Water Resistance tests include;
UV light exposure for 210 hours at 135 degrees to 140 degrees Fahrenheit
Accelerated aging with 25 - 6 hour soak and dry cycles.
Hydrostatic Pressuce (AATCC127 standards)
Shall not leak
Air Barrier be be durable
AC212 Accpetance Criteria
