JPL MHP-25 4-in Insulated 25-ft. Flex Duct
Description
Description
The JPL MHP-25 4-inch Insulated Flex Duct is a UL listed Class 1 insulated flexible air duct designed for durability and superior airflow efficiency.
This 25-foot fiberglass insulated flexible duct is ideal for 4-inch supply and return connections in low to medium pressure duct systems. Constructed with durable materials, the JPL insulated duct is designed with a spring steel wire helix, encapsulated in a 2-ply air-tight inner core, with a unique metalized reinforced vapor barrier surrounding the entire duct.
Key Features and Benefits of the JPL MHP-25 4-inch Insulated Flex Duct
- Efficient Thermal Performance: Available with fiberglass insulation in certified R6 or R8 value models, for excellent temperature control in indoor applications.
- Robust Construction: Features a spring steel wire helix enclosed by an oversized 3/8-inch airtight two-ply inner core and insulation. Metalized polyester reinforces its vapor barrier to enhance thermal performance.
- GREENGUARD Gold Certified and Formaldehyde Free: Ensures low chemical emissions and VOCs to ensure healthy indoor air.
- UL Listed and Labeled: This UL-181 Class 1 Air Duct conforms to strict safety and performance standards.
- Pressure Ratings: Maximum positive pressure is 6 inches w.g. (4-12 inches) and 4 inches w.g. (14-22 inches), and maximum negative pressure is 1 inch w.g. (4-10 inches) and 1/2 inch w.g. (12-22 inches).
- Versatile Applications: Perfect for general HVAC ducting and specific installations like bathroom fan exhaust systems.
Multiple Insulation Rated Models
Select the insulation-rated model ideal for your application to ensure maximum comfort, energy savings, and optimal system performance tailored specifically to your climate and HVAC requirements:
- JPL Insulation-Rated R6: Provides good thermal resistance typically used in standard residential heating and cooling and venting systems, where a balance of thermal efficiency, affordability and flexibility is needed.
- JPL Insulation-Rated R8: This higher-rated insulation offers superior thermal resistance, making it ideal for more extreme climates with significant temperature fluctuations, or when ducts run through unconditioned spaces where there's a significant temperature difference between the duct and surrounding air. R8 insulation can also offer greater efficiency in longer duct runs and configurations.
Sylvane's Expert Take
The JPL 4-inch Insulated Flex Duct is an excellent choice for homeowners and professionals looking for efficient and easy-to-install ductwork. Its versatile insulation performance of R6 or R8 effectively maintains consistent temperatures in indoor ventilation installations, while its advanced vapor barrier defends against moisture.
Given its UL certification, GREENGUARD Gold status, and JPL's long-trusted reputation within the ducting industry, it stands out as a reliable, safe, and sustainable option for any ventilation system.
