Advanced Walls: Continuous Exterior Insulation Factsheet

This document is designed to inform and provide resources to developers, architects, home builders, key trades, Raters/verifiers, and inspectors about continuous insulation for exterior walls.

As energy codes advanced across the Northwest, requirements to install building envelopes with less heat loss and gain, to build greater resiliency, and to reduce thermal bridging is leading builders and tradespeople to evaluate new wall designs and insulation strategies. The BetterBuiltNW team has identified several wall strategies that can assist builders in both meeting new codes, and in building homes that will produce comfort at the lowest home operating cost — including continuous exterior insulation.
