In January 2007, tests were conducted to study the effectiveness of Masonry Technology's Sure Cavity SCMM 2532 drainage plane product. These tests were supervised and independently verified by Stork Twin City Testing.
The test was conducted on two identical 4x8 wall panels. The only difference was that the Control Panel contained no drainage plane. It was a typically constructed thin veneer wall with a surface of scratch coat followed by metal lath, two layers of building paper and a layer of plywood. The MTI panel was exactly the same except for a layer of SCMM 2532 between the metal lath and the building paper.
WME or Wood Moisture Equivalent is a scale of moisture levels in wood. According to a variety of resources, moisture content in the 16% to 20% range is enough to support surface fungi. Moisture levels above 20% lead to various types of rot.
The MTI Panel stayed dry, with all layers reporting <10% Wood Moisture Equivalent over the course of a week following testing. The Control Panel with no drainage plane got wet and stayed wet longer, with layers remaining above 16% WME for six days.
Sure Cavity™ recently underwent 4 weeks of testing to see whether it harbored fungus or kept it at bay. The results: Sure Cavity™ is proven to be resistant to five fungi that are common to building construction and potentially harmful to occupants.

Testing has just been completed to see how Sure Cavity™ holds up against an important weathering agent: UV exposure. Sure Cavity™ proved itself again, and held strong during 9 solid weeks of intense UV exposure without any signs of damage.
