Insulated Heating and Air Conditioning Ducts

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.

Why Use Ultra-Duct?

• Reflective foil provides a barrier to radiant heat intrusion, enhances HVAC system performance
• Thin wall material maximizes duct interior, increasing air output
• Non-toxic
• Fiberless
• Tested & approved for Heat & A/C
• Lightweight
• Easy to install
• Available pre-cut for easy fold and tape or fully assembled
• Variety of standard sizes; custom sizes are our specialty
• UltraDuct products are ideal for any space-limiting application
