Types of Duct Insulation Wrap for HVAC Exterior

The duct insulation wrap for HVAC exterior is crucial. To maintain the temperature, the system must work efficiently. Thus, to ensure a smooth process of everything. HVAC cleaning Smyrna GA service is always available. Yet, to enhance Indoor air quality, it is advised to use an Insulated HVAC duct. Additionally, It also improves efficiency and reduces energy expenses.

The following article will take you to the depths of duct insulation.

Types of Duct Insulation for HVAC Exterior  

The following are the various types of Duct Insulation Wrap for the HVAC Exterior.

Duct Insulation Wrap for HVAC Exterior

Board Insulation

Indoor and outdoor commercial HVAC ducts isolated from HVAC insulation board products.
The most typical type of HVAC insulation is fiberglass. HVAC cleaning in Smyrna GA also provides mineral wool insulation.
It boards with a higher temperature rating. Industrial ducting uses it.


It is the one that is known everywhere. It is popular because of the ranges available under the capacity.HVAC cleaning Smyrna GA offers a range of crucial aspects. They include::  thicknesses, facing kinds, and product densities.

ASJ Facing:

A white poly-encapsulated paper jacketing is used for HVAC ductwork. It’s used in the interior only.

FRK Facing:

FRK paper jacketing is used on both interior and exterior HVAC ducting. They are also used on the exterior ducting with an aluminum protective covering.

Mineral wool Board Insulation:

It uses high-temperature pipelines up to 1200°F at max operating temperatures.

Rubber Sheets

HVAC cleaning Smyrna GA supplies rubber elastomers in chilled systems. It also provides chillers as closed-cell thermal insulation. The insulation of the rubber sheet does not absorb water from condensate.

Rubber Sheets have a rubber adhesive. It attaches the sheets to a chiller and stitches the sheets’ seams. Therefore, this makes it an ideal cold system insulator.

Aluminum Cladding

The membranes and tapes in aluminum cladding protect external HVAC UV. It also protects weather insulation.

Board Pins

Installing HVAC board insulation on ducting requires tools and fasteners.

Duct Wrap Insulation:
According to Commercial air duct and dryer vent cleaning Smyrna GA, Fiberglass Duct Wrap is a thermal insulation material. Interior heating and air conditioning ducts use it. Fiberglass Duct Wrap is 1-1/2″ thick. FRK Facing (Foil Reinforced Kraft) is 3/4# density. After wrapping the HVAC duct insulation around the circumference of the duct. All insulating wrap seams are sealed using FRK tapes.

  • Fiberglass Duct Wrap

The purpose of HVAC insulation specification is to decrease heat transfer. Fiberglass duct isolation can help with this in a planned and built system. Additionally, It assists control condensation. It also increases thermal performance in commercial and residential HVAC systems. Duct wrap insulation is also lightweight and simple to install.

  • Insulation Boards

Fibrous glass insulation boards are available outside of sealed sheet metal ducts. Furthermore, It is also applicable for housings, plenums. These are available in various densities and thicknesses. It is either unfaced or with reinforced foil (FSK). It can also be an all-service jacket (ASJ) vapor retarder facings. Colossal round or oval metal sheet ducts are flexible to match curving surfaces. 

Isover ClimCover Roll

Isover Climcover is a durable, flexible, and simple-to-handle glass mineral wool roll. Hence, A factory-applied aluminum foil front provides an inherent vapor barrier to it. ISOVER CLIMCOVER Slab Alu2 helps to avoid thermal losses and condensation. Therefore, The product is suitable for use with a later covering. It’s suited for low-level installations and outdoor use. It meets the requirements of Commercial air duct and dryer vent cleaning in Smyrna GA. Also, it provides procedures for thermal insulating materials. Pipelines, tanks, vessels, and ducting all use them. The ISOVER HVAC portfolio also includes thermal insulation materials. It is used for building equipment and industrial applications.

Weather Protection / Cladding:

Aluminum Claddings are protective coverings. In external applications, it serves as a vapor barrier. It also protects insulation boards from UV exposure and weather. HVAC cleaning Smyrna GA uses three types of aluminum cladding membranes:

  1. Flex-Clad 250 is a 25-mil thick aluminum cladding with a rubberized asphalt adhesive. Flex-Clad is also known as “self-healing.” Because it is an asphalt base layer seals any small penetrations.
  2. The most well-known cladding product on the market is Venture-Clad. Venture-Clad 1577 CW is a thin self-adhesive cladding. It is with a stucco embossed pattern that hides bubbles, wrinkles, and other flaws.
  3. Ideal Seal 777 is a thin self-adhesive cladding. It is with a stucco embossed pattern that hides bubbles, wrinkles, and other flaws. The Ideal Seal 777 is a less expensive version of the 3M Venture-Clad.

Pins / Fasteners:

Fiberglass duct board insulation and fiberglass duct wrap use the HVAC ductwork. Thus, This category contains all insulation pins and clips used in HVAC insulation. Commercial air duct and dryer vent cleaning in Smyrna, GA offers a variety of insulation pins. There are also a wide variety of fasteners.

  • Self-Sticking Insulation Hangers:

These pins have a self-adhesive foam backing on the 2 square bases. It is for quick and easy installation. It holds the insulation in place using a lock washer on the pin of these hangers. It is only for lightweight applications.

  • Perforated Base Insulation Hangers:

The perforated 2″ square base of these pins allows adhesive to build a solid grip. The most popular hangers are Perf-Pins. They are the strongest and come in a variety of lengths up to 12-1/2 inches.

  • Mini-Cupped Weld Pins:

The pin’s head, which welds the sheet metal duct, holds the insulation in place. Thus, these pins will need pin welder equipment.

Benefits of Duct Insulation Wrap

  • Thermal insulation

Decrease the amount of heat (or cold). The energy required is to maintain the desired air temperature while avoiding condensation formation.

  • Excellent acoustic characteristics

Decrease the amount of noise communicated through the HVAC system’s ductwork. It also reduces the noise by piping by a significant amount.

  • Fire prevention

To supply non-fuel isolation materials which don’t give users dangerous smoke.

  • Enhance Comfort

Clean air reaches rooms at ideal temperatures. It’s done by minimizing heat loss or gain from duct walls. Central air equipment can thus run at lower temperatures.
