ZircoFlex® is now offered in a wide range of sizes from A4 through to large sheet format (900mmx 550mm). It is also supplied in multi layers with ZircoFlex® II and ZircoFlex® lll delivering double and triple layer protection from heat. A temperature resistant self-adhesive backing option is also available. Testing against 5.25mm thick commercial double walled heatshield material shows that even a single sheet of ZircoFlex® offers 64 percent heat reduction compared to only 35 percent for the standard heatshield, even though ZircoFlex® is a third lighter. ZircoFlex® II reduces temperature by up to 77 percent and ZircoFlex® Ill by up to 85 percent.
