Insul-Bright Heat-Resistant Batting — 22" x 20 yards from The Warm Company is the thermal lining for oven mitts, pot holders, casserole carriers, and insulated bags — needle-punched polyester with a reflective metalized film that deflects heat away from hands.

Frequently Asked Questions

How does it actually resist heat?

The metalized layer reflects radiant heat away while the polyester fiber blocks conductive heat from hot cookware — two mechanisms in one batting.

Why can't it go in the microwave?

The metallic fibers arc under microwave energy. Microwave projects need 100% cotton Wrap-N-Zap instead — the two battings are complements, not substitutes.

Which way does the shiny side face?

Generally toward the heat source — outward in a pot holder, toward the hand in a mitt — but follow your specific pattern's construction instructions.

Does it work for insulated totes and lunch bags?

Yes — it keeps cold things cold and hot things hot, making it the standard for insulated grocery bags, lunch bags, and wine carriers.

Is a wider format available?

Yes — a 45" x 40-yard bolt for larger bags and high-volume production; the 22" width is optimized for kitchen accessory patterns.
