Introduction

The 5-inch insulated flex duct is an essential component in residential and commercial HVAC systems. It plays a crucial role in air distribution, optimizing both energy efficiency and comfort. Understanding its applications and benefits can facilitate better decision-making for HVAC design and installation.

Specifications of 5 Insulated Flex Duct

Typically, a 5 insulated flex duct consists of a flexible inner core surrounded by fiberglass insulation, covered by an outer protective layer. The specifications include:

• Diameter: 5 inches
• Insulation Thickness: R-4.2 to R-8
• Length: Varies, usually 25 feet per section

Common Applications

The primary applications of 5 insulated flex duct include:

• Residential HVAC Systems: Used to connect ductwork to air outlets.
• Commercial Buildings: Suitable for branch ducts and small area heating and cooling.
• Variable Air Volume Systems: Ensures flexibility in adjustment of air handling units.

Benefits of Insulated Flex Duct

The advantages of using insulated flex duct are:

• Energy Efficiency: Reduces heat loss or gain, improving HVAC system efficiency.
• Noise Reduction: Minimizes air noise due to soft material lined with insulation.
• Installation Ease: Flexible structure allows easy fitting in confined spaces.
