Description
Insul-Bright® Insulating Thermal Batting & Reflective Lining – 45" x 40 Yard Bolt
Add thermal insulation to quilts, pot holders, oven mitts, insulated bags, casserole covers, and other temperature-sensitive sewing projects with Insul-Bright® Insulating Thermal Lining. This generous 45" x 40-yard bulk bolt is ideal for frequent sewing, large projects, quilt shops, classrooms, studios, and makers who need a substantial supply of thermal batting.
Insul-Bright® is constructed with polyester fibers needle punched through a reflective metalized film. The polyester fibers help resist conductive heat transfer, while the reflective layer helps reflect radiant energy—hot or cold—back toward its source.
Flexible and easy to incorporate into quilted projects, Insul-Bright® is a versatile choice for pot holders, oven mitts, casserole covers and cozies, insulated lunch bags, tote bags, table accessories, and other hot- or cold-insulating sewing projects.
Its breathable construction is washable and designed for practical household projects. For projects involving hot items, cotton batting is recommended as an additional layer to help absorb steam vapor. Insul-Bright® itself is breathable, so steam can pass through the material.
With an extra-generous 45-inch width and 40 continuous yards, this bulk bolt provides plenty of material for large projects, production sewing, or multiple insulated accessories.
