Insul-Fleece™ is made from polyester fibers which are needle punched into a metalized Mylar® which reflects back to the source heat or cold*. It is soft and comfortable for use in clothing as well as home décor and accessories. Insul-Fleece™ can be sewn through and, once sewn, is machine washable and dryable. Keeps hot things hot longer and cool things cool longer.
**If you plan to use the Insul-Fleece™ in a project that will come in contact with any object over 400? we recommend that you place a layer or two of cotton batting between the Insul-Fleece™ and the fabric that will come in contact with the hot object. This will help prevent the Polyester in the Insul-Fleece™ from melting.
**Insul-Fleece™ is not heat proof or fire resistant
**As Insul-Fleece™ is made of 6.25% Metalized Mylar, it should never be used in the microwave.
