A versatile sheet that comes in handy for various purposes. ～ See the manufacturer's website for details ～ ↓↓↓ Excerpts below ↓↓↓ Tyvek® Silver is a heat-reflective sheet made by vapor-depositing aluminum on high-density polyethylene non-woven fabric Tyvek®, and further applying an anti-oxidation resin coating to each fiber to prevent aluminum deterioration.
