Insul-Bright Insulated Batting is a sewing notion that should be in every sewing room!
Insul-Bright Fiber content 93.75% polyester and 6.25% metalized polyester
Insul Bright is a polyester batting with mylar woven into the batting. Polyester fibers are needle punched thru the reflective metabolized polyester film.
Mylar helps to reflect hot and cold keeping things hotter or cooler for longer.
Insul Bright is a brand name from The Warm Company.
There are other companies that make their own brand of Insulated Batting.
Some insulated batting has mylar woven into the batting, while some batting has the mylar on one side which is clearly visible.
Other project ideas with Insulated Batting:
Can Insul-Bright be used in the microwave? NO because of metalized fiber. (Pellon makes a cotton quilt batting for the microwave called Wrap-n-Zap.)
What temperature will this product withstand? Potholders made with this product can go up to 400 degrees. If your oven temperature is warmer, just use a couple of potholders to be on the safe side.
Is there a right side or a wrong side? If you are using the woven batting there is NO right or wrong side. If you are using an insulated batting with a clear visible metalized side called Therma-Flec, that would be the side you use to pick up your hot or cold items with, and you can cover the other side of batting with cotton fabric.
