Working as a radiant barrier, Radiant Fabric can block radiant heat in both directions while providing shade and blocking heat from the sun. To make it more cosmetically appealing, Radiant Fabric is white on one side. Radiant Fabric can be sewn on a regular sewing machine, or even heat seamed to appear continuous and seamless. If you add Radiant Fabric as a curtain liner, you will feel the difference of a radiant barrier without having to see it.
Radiant Fabric can be used as window curtains and many other applications.  Use this product to cover your car, boat, or ATV. Radiant Fabric is outstanding when used to make cold weather clothing such as gloves, jackets, pants, and hats.  Use as a lightweight and very warm solution for comforters, blankets, and sleeping bags.  Keep food warm when used as grocery totes, pizza delivery bags, or casserole bags.  Radiant Fabric can be used as a tarp or incorporated into tents, awnings, solar screens, and canopies.  Whether being used to block heat, retain heat, or as a condensation barrier, the applications for Radiant Fabric are almost countless.
Light colored fabrics, while resisting heat, allow light to pass easily. While typical blackout fabrics can impede light, they absorb more heat, adding to the energy problem. Radiant Fabric blocks nearly all of the light while reflecting 95% of the radiant heat. Another aspect of using typical blackout cloth is the fact that, because the cloth is a closed weave cloth, there is a difficulty in providing adequate ventilation. This can leave your home feeling stuffy, even when your window is open. Radiant Fabric doesn't have this problem because it is also perforated, allowing breath-ability and reducing condensation.
