What is an IGS Storm Window?

A low-profile design, innovative and patented frame systems, and an extensive color pallet to match your existing trim colors are features that result in a product that seamlessly integrates with your existing window. QUANTAPANEL IGS can be installed on either the exterior or interior of your existing window.

Every QUANTAPANEL Architectural Low-e Storm Window is robotically manufactured, and custom-built based on field measurements for the window upon which it will be installed.
