Does DoubleTack® have good insulation properties?

Does DoubleTack® 2/side adhesive film have good insulation properties? Sort of. DoubleTack is made from polyester film, which has great insulation properties. However, its adhesive coatings are not meant for expo-sure to elevated or reduced temperatures. Therefore we can not recommend this material for any sort of insulation application.
We can, on a custom basis, make you a pressure-sensitive adhesive (PSA) film with adhesives that are optimized for exposure to a specific elevated or reduced temperature. Minimums will apply.
