If you need high temperature

Would Recommend

As others have mentioned the glue always fails and you will need a tape to keep it secure. Even with that minor issue I use it for hot water heating. Most other products won't work at hot water heating system temperatures. It is fiberglass so be careful when you cut it outside your home.
