What is Ultra-Duct?

Ultra-Duct products are insulated air conditioning ducts made from reflective insulation for recreational vehicles, conversion vans and specialty vehicles. Consisting of a 1/8-inch-thick* polystyrene core sandwiched between two layers of aluminum foil, Ultra-Duct achieves outstanding airflow in space-constricted applications.

*Allow for the variance of .063"
