Superior Protection and Performance for Post-Frame Structures

Experience next-level efficiency and peace of mind with FI-FOIL® Reflective Bubble Insulation (RBI). Every roll of RBI Shield™ is precisely formulated and manufactured to provide exceptional thermal performance to improve living and working conditions inside your post-frame structures.

Insulation Quality Matters

Our R&D team has researched, tested, and selected several compounds in the formulation to enhance tensile strength and pliability for a more puncture-resistant bubble and a premium white polymer surface that wont crack, pit, chalk, peel, or discolor over time.

Our unique manufacturing process allows us to pack more air in each bubble, and the premium polymer and/or reflective films are all bonded together in a one-step process, allowing our bubble insulation to maintain a greater thickness and strength versus others on the market.

RBI Shield™ insulation rolls are remarkably easy to cut, install and serve as a highly effective vapor barrier when all joints and eaves are properly sealed.

Superior Thermal Performance Year-Round

Utilizing our reflective insulation technology will keep your buildings notably cooler in the summer and warmer in the winter. RBI Shield™ reflects 95% of radiant heat, which makes a real difference in lowering monthly energy costs and increasing comfort to protect your assets–whether it is livestock, machinery, agricultural foods, other consumables, or clients that drive your business.

Available in single or double bubble and in a variety of widths for the most cost-effective way to insulate your post frame build.
