HEADER WRAP (HF) HEADER WRAP INSULTHERM (HF) is extremely high temperature resistant. Commonly used for automotive and high performance headers and exhausts. Manufactured from texturised fibreglass yarns and woven into a strong and flexible wrap with vermiulite coating. HEADER WRAP reduces underhood temperatures up to 70%, increases horsepower and fuel efficiency. Techflex Header Wrap works by holding heat within the header, which creates a better exhaust flow.
