Abstract: Disclosed is a textile comprising a woven fabric and a layer of a low emissivity material disposed on the woven fabric, wherein the layer of low emissivity material is vapor deposited. The woven fabric has a yarn size of no greater than 30D and a weight no greater than 55 gsm. At least one coating layer vapor may be deposited adjacent the low emissivity layer. The woven fabric may comprise one or more of a nylon or a polyester. The textile may exhibit an increase in insulation ability of at least 10% compared to a substantially similar woven fabric in the absence of the low emissivity layer when tested together with a fibrous sheet insulation and another untreated woven fabric in accordance with ASTM-F1868 Part A.
