Insul-Bright Heat-Resistant Batting in the 22" x 20-yard bolt from The Warm Company is the essential thermal lining for oven mitts, pot holders, casserole carriers, insulated bags, and any sewn project that must handle heat — a needle-punched polyester batting with reflective metalized fibers that deflect heat and protect hands from burns.
Top 10 Questions About Insul-Bright Heat-Resistant Batting
Q: What makes Insul-Bright heat-resistant?
A: Insul-Bright uses needle-punched polyester fibers woven through a reflective metalized polyester film. The metallic layer reflects radiant heat away from the hands, while the polyester fiber creates a thermal barrier that insulates against conductive heat from hot pots, pans, and dishes.
Q: Is Insul-Bright safe for oven use?
A: Yes — Insul-Bright is specifically designed for oven mitts, pot holders, and casserole carriers used at standard oven temperatures. Always pair it with appropriate heat-safe outer fabrics (100% cotton is recommended) for full protection.
Q: Is Insul-Bright microwave safe?
A: Insul-Bright contains metallic fibers and should NOT be used in the microwave. For microwaveable projects, use Wrap-N-Zap 100% cotton batting instead. Insul-Bright is designed for conventional oven and stovetop heat protection only.
Q: What is the 22" width ideal for?
A: The 22" width is specifically suited for oven mitt pairs, pot holder sets, mug rugs, casserole carriers, and similar kitchen-sized projects. It cuts efficiently for standard oven mitt and pot holder patterns with minimal waste.
Q: How do I sew with Insul-Bright?
A: Sew it like standard batting — it feeds through a domestic sewing machine without special handling. Use a standard needle and moderate stitch length. The metalized surface can be placed on either side depending on your project construction.
Q: Is Insul-Bright washable?
A: Yes — finished projects made with Insul-Bright are machine washable. Wash in warm water and tumble dry on low. The reflective properties are maintained through regular laundering.
Q: How many oven mitts can I make from a 20-yard bolt?
A: At 22" x 20 yards, a bolt typically provides enough Insul-Bright for 30–40 standard oven mitt pairs or 50–60 pot holders, making it an excellent value for craft fair sellers and gift makers.
Q: Does the shiny side of Insul-Bright face in or out in construction?
A: Typically the shiny (metalized) side faces toward the heat source — outward in a pot holder or toward the hand in an oven mitt. However, construction method varies by pattern, so always follow the specific pattern instructions.
Q: Can I use Insul-Bright for insulated grocery bags and wine totes?
A: Yes — Insul-Bright is popular for insulated tote bags, lunch bags, and wine carriers where thermal insulation is needed. It keeps cold items cold and hot items hot, making it ideal for functional insulated bag projects.
Q: Is Insul-Bright available in wider widths than 22"?
A: Yes — Insul-Bright is also available in 45" x 40-yard bolts for larger project needs. The 22" width is optimized for kitchen accessories; the 45" width suits larger insulated bag and wearable projects.
