Insul-Bright 45 inch x 40 yard heat resistant batting large roll production sewing

Insul-Bright at Production Scale

The Insul-Bright 45 inch x 40 Yard bolt brings the Warm Company's reflective heat-resistant batting to a production-friendly format: 45 inches wide (the standard garment sewing width) and 40 yards long. For shops, studios, quilt teachers, and serious makers who produce oven mitts, casserole carriers, lunch bags, and other insulated projects in volume, this bolt dramatically reduces the per-project cost and eliminates frequent small-quantity reorders.

Why the 45-Inch Width Matters

The 22-inch format of the standard Insul-Bright bolt is perfect for small individual projects -- oven mitts, mug cozies, small pouches. The 45-inch width opens up larger project categories: full-width casserole carrier panels, wide lunch bag bodies, tote bag panels with full-width insulation coverage, and any project where the 22-inch width requires seaming the Insul-Bright to achieve the needed coverage. Garment sewists making insulated vests, jackets, and quilted outerwear benefit from the 45-inch width for seamless panel coverage aligned with standard fabric width conventions.

The Same Reflective Technology

Identical construction to the 22-inch format: polyester fibers needle-punched through a metalized reflective film that reflects infrared heat away from the user. The same heat protection principles, the same microwave-safety restrictions (never microwave), and the same washability apply at this larger scale.

Working With the 45-Inch Format

All the same principles as the 22-inch format apply: shiny side toward heat source, always use multiple layers for oven-contact applications, pair with 100% cotton fabric layers, never microwave. The 45-inch width can be cut down to any needed dimension with scissors or rotary cutter. Store the bolt rolled, not folded, to prevent permanent creases in the reflective film layer.

Frequently Asked Questions

Is this the same product as the 22-inch Insul-Bright, just wider?

Yes -- identical heat-resistant reflective construction. The width difference is the only distinction. All usage, care, and safety guidelines are identical.

How many standard oven mitt panels does 40 yards yield?

A standard oven mitt uses approximately 2 layers of Insul-Bright at 14x18 inch per mitt. From a 45-inch wide bolt you can cut 3 mitt panels per row (45 divided by 15 inches). At 2 layers per mitt and 40 yards of length, a single bolt yields several hundred individual mitt insulation panels depending on your specific pattern dimensions.

Can I cut this with a standard rotary cutter?

Yes. The reflective film layer cuts cleanly with a sharp rotary blade. Use a straight edge for the cleanest results. Replace the blade after extended cutting through the reflective layer as it dulls faster than fabric cutting.
