StoGuard Passes the Test in Boston
BEC Air Barrier Challenge

                                          
                                     Ten Teams Attempt To Build, Test, and Pass ASTM Tests


Sto Corp., the innovative world leader in cladding, coating, and restoration systems, was the only entity to fully pass both air and moisture testing during a recent BEC/BSA 2010 Air Barrier Design Challenge held in late May.

Hosted by Architectural Testing Inc. (ATI) in Chelmsford, Mass., ten teams of practicing design and construction professionals assembled 4’ x 8’ building envelope mock-up panels with a variety of membrane and fluid-applied air and moisture barrier systems. The Sto Team used StoGuard which was the only product tested that did not leak in both the air and water tests, including at the sensitive material joints or at screw holes.

The two testing methods  used in the challenge were the ASTM E 783 (field test for air leakage) and the ASTM E 1105 (field test for moisture leakage).

“Even though all the wall assemblies in this test passed the air leakage test, Sto was the only one that had absolutely no moisture leakage,” stated Lisa Petsko, Sto product manager for StoGuard. “The Challenge results point to the fact that a “thicker” membrane is not always better, meaning that membrane systems that claim the they are more effective because they are thicker (sometimes up to 90 mils), did not perform as well as a fluid-applied system like StoGuard at around 6 mils on the wall Why pay for more when it is not needed.” 

StoGuard also has code recognition where many of its competitors lack recognition. This gives StoGuard a performance advantage with industry-proven testing.

StoGuard can be used underneath wood, vinyl, cement siding, cement stucco and other exterior insulation and finish systems.

The StoGuard assembly consists of the following: 
>> StoGuard joint treatment – various options available.
>> Sto Gold Coat? or Sto EmeraldCoat? both waterproof coatings applied by spray, roller, or brush to wall sheathing, prepared concrete, or concrete masonry wall construction.  Sto Gold Coat® is specially formulated for use under EIFS and other claddings while Sto EmeraldCoat? is specially formulated for use under stucco and other claddings.

Together these components create a seamless, structural air and waterproof barrier that greatly improves indoor occupant comfort and reduces energy costs in comparison to house wraps in wall assemblies.
