Edgetech’s technical director to present at GPD China

According to Tracy Rogers, technical director, Edgetech I.G., Cambridge, Ohio, condensation is the third thermal performance parameter alongside U-factor andsolar heat gain coefficient. In his Glass Processing Days China presentation, Rogers will cover health concerns and the effects of condensation on the integrity and long-term performance of fenestration systems, according to an April 19 release. This year’s GPD conference, to be held June 2-3, in Beijing, will focus on challenges and solutions facing architectural glass and solar applications.

Rogers’ technical paper titled Considerations for the Condensation Resistance of Fenestration Assemblies provides an in-depth look at U-factor and condensation resistance basics, system ratings for thermal performance and the relative effects of U-factor and condensation resistance using third-party data.

“Performance factors that may have a minimal impact on U-factor and/or SHGC may be critical in the prevention of condensation formation that may, if not controlled, lead to health concerns and building component or system damage,” Rogers said in the release. “At GPD China, I will compare the difference between the performance of fenestration products relative to U-factor and condensation resistance and outline principal design features to improve the latter.”

According to third-party, independent testing, Edgetech’s Super Spacer provides the leading condensation resistance of any spacer in North America – up to 131 percent better than metal bar, the release stated.
