When is insulating glass fogging not considered failure?

The appearance of condensation between the panes of an insulated glass (IG) unit is an indication the hermetic seal of the unit has been breached or compromised, thereby allowing outside moist air to infiltrate the air space where it condenses on the interpane surfaces of the glass. One could argue semantics, but this is the generally accepted meaning of the word “failure” as it relates to IG units. In this case, the failure is characterized by an ever-present condensation between the glass panes.

Fluid-applied thermal break coatings 101

Architects designing with concrete balconies, cantilevered beams, roof penetrations, parapets, canopies, spandrel glass, and other ornamental architectural features are often limited in executing these design elements because they can create thermal bridges that extend beyond the insulation systems within the building envelope.

Continuing the Debate on Solar-driven Moisture

Our January 2013 article, “Ensuring Moisture Protection for Manufactured Stone,” written by Jeff Diqui, Arch. Eng., CSI, resulted in a letter to the editor from another frequent contributor to The Construction Specifier.

In the spring, Maria Spinu, PhD, LEED AP, e-mailed her comments:

I want to compliment Mr. Diqui on a generally well-written and informative article, but I wish to address the statements made … Continue reading Continuing the Debate on Solar-driven Moisture
