EIFS-Moisture

Reach A Higher State Of EIFS Consciousness

Moisture performance of EIFS is misunderstood and it continues to be a subject of consternation.  Much of the confusion stems from the fact that design criteria for EIFS assemblies incorporating cavity insulation plus outbound insulation panels have not been adequately addressed by the EIFS industry.  Manufacturers place the responsibility of assembly design squarely on the…

Wall Rainscreen

Is Your Rainscreen Deceiving You?

The rainscreen concept, now almost 50 years old, has only recently gained traction in current building practices.  As we explore here, simply placing a capillary break behind your cladding may not provide the protection you expect. Moisture management has always depended on a balance between the entry of water and the capability to remove it. …

Fiber Cement Panels

Unexpected Expansion Of Fiber Cement Panels

Fiber cement panels have become a preferred cladding system for a clean, monolithic aesthetic typically associated with more expensive claddings such as stucco or EIFS.   But the industry is seeing an alarming number of panel failures resulting in costly building repairs.  Many of these failures point to panel joint design and excess movement. Notwithstanding requirements…

Moisture Management

Doctrines For Moisture Control

Problems associated with water-induced failures became more prevalent in the 1980’s as a result of changing paradigms in design and construction practices.   These failures are often attributed to air-tight, energy-efficient designs initiated during the global energy crisis of the 1970’s.  Although applicable, this over-simplification ignores the fact that many energy-efficient buildings of this era have…

Building Failures

Redefining Building Failure

The phrase ‘building failure’ conjures images of fatal effects such as sudden collapse, material loss, and major structural defects.   But for decades the industry has embraced broader definitions – all representative of conditions that adversely affect the intended service life of components or assemblies.  For example, the Canadian Standards Association (S478-95) defines failure as the loss of performance…
