This newly built single-family residence in Magnolia was originally designed for stucco, but the owners’ desire for continuous insulation required switching to an exterior insulation and finishing system (EIFS) system.
Without detailed drawings, J.J. Jefferson’s project team worked with the homeowner and general contractor to incorporate all the necessary manufacturer’s details for a complete water-drainage EIFS system. Senergy’s channeled adhesive system with a fluid-applied weather barrier was chosen.
Senershield weather barrier was applied to the home’s entire plywood substrate to ensure the siding transitions had a continuous barrier. Using notched trowels, an expanded polystyrene adhesive was applied to form the drainage plane and coordinated with proper sheet-metal flashings and a drainage track to direct moisture out of the building. Specialty expanded polystyrene shapes at the cornice, siding transitions and windowsills were designed and mocked up on the job for design approval.
Due to window delays, the summer construction schedule slid into fall, which brought the Seattle rain. Additional scaffolding and covering was needed to protect the installation during inclement weather.
Judge’s comment: “The owners of this home will benefit from the many features EIFS brings to a project. The classic appearance, outstanding insulating value, superb air and weather barrier along with flawless installation make this a crown jewel residence in the Magnolia neighborhood of Seattle.”
