For over 35 years, brothers Jeff and Dave Tom have been incorporating loyalty, trust, high performance, and integrity as core values in their family-owned business, Engineered Interior Windows (EIW). As an active member of the International Window Film Association, EIW applies extensive knowledge, experience, and professionalism to each service and product offered. EIW works with building managers and owners, construction managers, contractors, and architects to create cost effective, energy saving, and secure window films. All EIW systems include a 5 year Manufacturer Warranty, and they are installed without modifying or replacing existing windows. These window systems control thermal and moisture factors without the distraction of an obvious window addition. Various styles, colors, and systems are available in our interior storm system inventory. We work with virtually any window to create safe, secure, and noise-controlled working or living environments.
