About IWI

Climbing to New Heights of Service & Satisfaction

Intermountain West Insulation is Eastern Washington’s local insulation contractor. Since 1981, we have offered advanced insulation solutions based in building science for both new construction and existing projects. We have since expanded, with added locations offering garage door installation and painting services. We are licensed, bonded and insured to ensure that we maintain our good reputation and service for decades to come.
