Introduction

R8 flex duct is a critical component in many HVAC systems, known for its superior thermal efficiency and flexibility. This article details its properties, uses, and benefits within HVAC systems, along with a look at solutions offered by Subo Company.

R8 Flex Duct Properties

R8 flex duct is characterized by its high thermal resistance, rated at R-8, translating to an insulation value of approximately 8 per inch of thickness. This ducting typically features a diameter range of 4 to 20 inches, accommodating various HVAC system sizes and needs.

It comprises a metallic inner layer and a protective outer jacket. The core is typically made of spiral metal wire and a flexible plastic covering, ensuring durability and resistance to punctures.

Applications in HVAC Systems

R8 flex duct is predominantly used in residential and commercial HVAC systems to distribute conditioned air efficiently. It is commonly applied in:

• Duct runs where high thermal efficiency is required.
• Spaces with limited room for rigid ducts due to its flexibility.
• Situations where reduced air leakage is a priority, thanks to its robust construction.

Advantages of R8 Flex Duct

The R8 designation indicates a higher level of insulation, resulting in reduced thermal loss compared to lower R-value ducts, such as R4 or R6. This efficiency leads to energy savings, potentially reducing heating and cooling costs by up to 15%.

Additionally, its flexibility simplifies installation, potentially cutting labor costs and time by 20% compared to rigid ductwork. The outer laminate jacket resists damage, extending the service life of the duct.
