Description
A full case of Insul-Bright in 45" x 1-yard packages, for quilt shops, craft sellers, classrooms and studios that make or sell insulated goods in volume. Insul-Bright is a needle-punched thermal lining: polyester fibers punched through a reflective metalized polyester film, so the fibers slow conductive heat and the film reflects radiant heat or cold back toward its source. It sews like a light batting, stays flexible, is breathable, does not shrink, and once quilted into a project it machine washes and dries.
Each package is one yard, the natural unit for a class kit or a batch of pot holders and mitts, which is why the case format beats a bolt for teaching and resale. For hot projects The Warm Company recommends a layer of cotton batting with the Insul-Bright to absorb steam, and Insul-Bright is not recommended for microwave use because of the metalized film; use Pellon Wrap-N-Zap for anything microwaved.
If you would rather cut from continuous yardage, the same material comes on 22" x 20-yard and 45" x 40-yard bolts.

- Case of packages or a bolt?
- Buy the case when you hand Insul-Bright out by the yard: class kits, shop shelves, craft-fair production where one yard is a batch. Buy a bolt when you cut your own lengths and want the lowest cost per yard; the 22" bolt suits pot holders and mitts, the 45" x 40-yard bolt suits carriers and bags. Insul-Bright 45" x 40 yd bolt
- Is Insul-Bright microwave safe?
- No. Insul-Bright contains a metalized polyester film and is not recommended for microwave use. For bowl cozies and anything that will be microwaved, use Pellon Wrap-N-Zap, a 100% cotton batting made for that job. Insul-Bright is for oven mitts, pot holders, casserole carriers and lunch bags that stay out of the microwave. Pellon Wrap-N-Zap 45" x 1 yd package
- Do I need cotton batting with Insul-Bright for hot projects?
- For anything that handles hot items, yes. Insul-Bright is breathable, so steam from a hot dish can pass through it. The Warm Company recommends adding a layer of cotton batting (Warm & Natural is the usual choice) to absorb that steam. A typical oven mitt or pot holder is outer fabric, Insul-Bright, cotton batting, lining, with the shiny side of the Insul-Bright facing the heat. Warm & Natural cotton batting full case
- Is one layer of Insul-Bright enough?
- One layer handles hot and cold projects. For items that touch hot dishes, add a layer of cotton batting rather than a second layer of Insul-Bright; the cotton absorbs steam that passes through the reflective layer.
- Insul-Bright vs Insul-Shine?
- Insul-Bright has polyester fibers needle-punched through a reflective metalized film, so the film is inside the batting and the product looks like a grey-flecked batting. Insul-Shine has a shiny metallized polyester surface pin-welded to one face of a polyester batting, so the reflective layer is exposed, wipes clean and is water resistant. Use Insul-Bright for mitts, pot holders and casserole covers; use Insul-Shine for lunch bags, soft coolers, bottle carriers and anywhere you want the metallic face showing or wipeable.

- Is Insul-Bright heat-proof?
- No. Insul-Bright is a thermal insulating material, not a heat-proof or fire-proof barrier. The polyester fibers slow conductive heat and the metalized film reflects radiant heat, which is why it works in mitts and pot holders, but you still need proper construction and the cotton batting layer, and it is not a substitute for a trivet under a hot pan.
