Get the Building Envelope Right, on Paper and in the Field.
Northwest Enclosure Consulting helps developers, owners, architects, and general contractors control water, air, vapor, and heat in multifamily buildings, from the first wall section to final inspection and through the life of the building.
Building Science Applied to Every Detail
During design, we review architectural drawings, details, and specifications, starting as early as Schematic Design, and mark up each set with recommendations that improve constructability and long-term performance. During construction, we review installations in the field, document deficiencies with clear recommendations, and oversee performance testing.
The goal is to resolve water, air, vapor, and thermal issues in the design on paper and in the installation in the field, so they never compromise the long-term integrity of the building.
Our background spans enclosure consulting, thermal and hygrothermal modeling, moisture investigations, architectural design, energy retrofits, and hands-on construction, grounded in degrees in mechanical engineering and architecture.
We work across Washington, from Vancouver north to Tacoma and east to Yakima, and across Oregon, from the coast to Eugene and Bend.
