Insul-Bright® Insulating Thermal Lining – 45" x 1 Yard – Full Case

Insul-Bright® Insulating Thermal Lining – 45" x 1 Yard – Full Case

Create practical insulated sewing and quilting projects with Insul-Bright® Insulating Thermal Lining. Available here as a full case of 45" x 1-yard packages, Insul-Bright® combines polyester fibers with a reflective metalized polyester film to help manage radiant heat and cold in temperature-sensitive projects.

Insul-Bright® is constructed by needle punching polyester fibers 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.

This combination makes Insul-Bright® an excellent thermal lining for projects such as potholders, oven mitts, casserole covers and cozies, tea cozies, table runners, placemats, insulated bags, and other temperature-sensitive sewing projects.

The needle-punched construction is breathable, easy to sew through, and designed to withstand laundering. Once incorporated into a properly constructed quilted project, Insul-Bright® can be machine washed and dried.

For projects involving hot items, cotton batting is recommended as an additional layer to help absorb steam vapor. Steam can pass through Insul-Bright®, so appropriate project construction and additional protective layers are important when making oven mitts, potholders, casserole cozies, and similar items.

The full-case format is a convenient choice for quilt shops, sewing and craft retailers, classrooms, studios, professional makers, and customers who regularly create insulated sewing projects.

What is Insul-Bright®?
Insul-Bright® is a needle-punched reflective thermal lining made with polyester fibers and a metalized polyester film. It is designed for sewing and quilting projects where thermal insulation is needed.

How does Insul-Bright® work?
The polyester fibers help resist conductive heat transfer, while the reflective metalized film helps reflect radiant energy—hot or cold—back toward its source.

What can Insul-Bright® be used for?
Insul-Bright® is commonly used in potholders, oven mitts, casserole cozies, casserole covers, tea cozies, table runners, placemats, insulated bags, and other temperature-sensitive sewing projects.

Can Insul-Bright® be used for potholders and oven mitts?
Yes, but proper construction is important. For hot projects, the manufacturer recommends using cotton batting along with Insul-Bright® to help absorb steam vapor.

Why should cotton batting be added to hot projects?
When a hot object is introduced to a cooler environment, steam vapor can be produced. That vapor may pass through Insul-Bright®. A layer of cotton batting can help absorb the moisture and provide an additional protective layer in properly constructed hot-item projects.

Is one layer of Insul-Bright® enough?
The provided product information states that one layer of Insul-Bright® can be used for hot and cold projects. However, cotton batting is recommended as an additional layer for projects involving hot items to help manage steam vapor.

Is Insul-Bright® heat-proof?
No. Insul-Bright® should be considered a reflective thermal insulating material, not a heat-proof or fire-proof barrier. Appropriate construction and additional protective layers should be used for projects that handle hot objects.

Can Insul-Bright® be used for cold items?
Yes. Its reflective construction can also be incorporated into projects designed to help insulate cold items, including appropriate insulated bags and carriers.

Is Insul-Bright® microwave-safe?
No. Insul-Bright® is not recommended for microwave use. Because it contains a metalized reflective film, it should not be used in projects intended to go into a microwave.

Can Insul-Bright® be washed?
Yes. Once incorporated into a quilted project, Insul-Bright® can be machine washed and dried according to the provided product information.

Does Insul-Bright® shrink?
According to the provided product information, Insul-Bright® does not shrink.

Does Insul-Bright® need to be pre-washed?
No. Pre-washing is optional.

Can Insul-Bright® be ironed?
If necessary, the completed project may be ironed using a low setting, according to the provided care instructions.

Can Insul-Bright® be used in clothing?
Yes, although the reflective film can create a noticeable crinkling sound when the material moves.

What size is each package in this full case?
Each package is 1 yard long x 45 inches wide. This listing is for a full case.

Who is a full case of Insul-Bright® best for?
The full-case format is especially useful for quilt shops, sewing and craft retailers, classrooms, studios, professional makers, and high-volume crafters who regularly make insulated sewing projects.
