SHA plans to use EIFS on future renovations, thanks partly to the product’s success at Cal-Mor Circle.

Cal-Mor Circle is part of a Seattle Housing Authority Homeworks program that is upgrading and repairing several SHA properties in multiple phases.

Joseph J. Jefferson & Son has finished five projects so far, with most of the work involving upgrades to the structural masonry exteriors. Several of the original masonry buildings had allowed water to migrate through the exterior masonry and into the interior finishes. To fix the leaks, Senergy base coat, mesh and finish were applied to the masonry.

Cal-Mor Circle was unique in that SHA decided to install a full exterior insulation finish system with 2.5 inches of foam insulation over the original masonry exterior. SHA performed a number of tests on the EIFS system during and after construction to ensure proper adhesion and to determine the viability of EIFS renovations on future projects.

SHA has specified EIFS for additional properties due to its long-term energy savings.

Judge’s comment: “By using a new EIFS exterior cladding, the architect got the three key things the building owner needed: energy cost saving, stopping the moisture issues, and a more attractive building. The workmanship was excellent.”
