New test data below proving all siding leaks and the conclusions highly suggested the use of FURRING STRIPS as the BEST means of preventing moisture build up behind siding and the BEST installation method to allow maximum Drainage and Drying for exterior cladding materials.

Understanding the Rain Screen Principle Rain Penetration, DSA, Deutsche Steinzburg America, Inc. "Rain screen walls provide an important advantage over single solid walls in that they can afford complete protection"

Why Don't They Build Houses Like They Used To?
"a vertical path for moisture to move behind the cladding is critical. Housewrap has proved in many cases to be insufficient. Furring strips or some other secondary protection is considered critical"

"The number of contractors reporting moisture problems (water penetration) behind vinyl siding continues to increase. Last year, 16% experienced this problem, and in 2005 more than 20% reported it-an overall increase of 31%. Most contractors attributed this deficiency to poor installation."
By William A. Lotz, P.E., Aug 1, 2002
"In other words, do not create a vapor dam in the wall when there is already a moisture problem. Doing so is like wearing rubber gloves over hands with a skin infection." Read More

"Worse yet, 84% of those surveyed said they would not purchase a home from a builder who had a mold problem in the past, and 48% said they'd consider filing a lawsuit against the builder." "It may cost more up-front to build a home that performs properly, in every aspect, but the quality control processes afforded under a building science approach can reduce moisture-related problems"
"In addition, home buyers will receive homes that are more comfortable and energy efficient, providing better value than homes built just a few years ago. Moreover, satisfied home buyers help drive referrals and differentiate builders and contractors from the competition."

"The solution, according to Nicklas, is installing a mechanical ventilation system and continuous air barrier on all six sides of the building." Read More
Rainscreen/fiber cement, by Thomas Lundberg "even when using caulked lap siding, high wind causes water to be drawn under the boards due to the air pressure differential between the cladding's face and backside."
"Builders in coastal regions should strongly consider some form of rainscreen to reduce the risk of sheathing mold."

Rain Penetration and its control
"water entry resulting from an air pressure difference can be controlled by the introduction of an air space. When the air pressures both outside and inside a wetted plane are equal, there is no air pressure difference to move the water inward."
"It has, however, been shown that through-wall penetration of rain can be prevented by incorporating an air chamber into the joint or wall where the air pressure is always equal to that on the outside."
"uncontrolled partial penetration, which is less frequently recognized, can permit undesirable quantities of water within the wall."
"This design minimizes the wind pressure difference across the exterior cladding rain screen thus reducing the predominant force that drives rain into the wall."
