Duct wrap is used to cover ductwork. There are different types, such as Cellulose, Fiberglass and Elastomeric foam. It’s important to choose the type that will best protect your ductwork. This article will discuss each type, including fire-rated ductwrap.
Fire-rated ductwrap
Fire-rated ductwrap can be a great option for protecting commercial air ducts. It offers excellent insulating and space-saving features and offers an alternative to conventional, bulky fire protection methods. 3M Fire Barrier Duct Wrap 615+ is an excellent example of this product. It is often used in ventilation and grease ducts in commercial kitchens.
Depending on the type of system installed, some ducts will have to be fire-rated. Fire-rated ductwrap can be installed through ductwork that is six inches or 18 inches from a fire-rated wall. Once in place, it should be applied continuously to the ductwork. The owner will engage an independent testing agency to inspect the work. The agency will prepare a report that indicates whether the work was completed according to contract documents.
Fire-rated ductwork is made of a fire-resisting material that is tested by exposing it to fire. It provides up to four hours of protection. It also has a thermal rating. Some duct wraps, such as FireMaster FastWrap XLS, are fire-rated up to 1200 degrees Fahrenheit. The fire-resistant material is encapsulated in a durable fiberglass-reinforced foil facing. It is also lightweight and easy to install.
The Fire Barrier Duct Wrap 615+ is designed for use on both air and grease ducts. It offers a significant cost savings over traditional fire-rated shaft wall enclosures. It also features an attractive silver foil finish with the 3M logo. It offers a long shelf life and is certified for use according to AS1530.4. Besides fire resistance, it also eliminates dangerous fibres.
Flexible fire wrap products are now widely accepted by code officials. They meet the requirements of ASTM E119 and UL 263, which are recognized as valid fire exposure standards. These fire wraps are also widely used by architects and engineers.
Fiberglass ductwrap
Fiberglass duct wrap is an effective thermal-resistance insulation material used in residential and commercial ducts. It also enhances the acoustic performance of HVAC components. Its main benefits include thermal resistance ranging from 4 OC to 121 OC and excellent moisture resistance. These characteristics are beneficial for boosting the market growth of fiberglass duct wrap. Listed below are some of the major applications of fiberglass duct wrap insulation.
Fiberglass duct wrap insulation market is estimated to be worth USD 1.5 billion in 2017 and reach 900 million square meters by 2024. Demand for the product is expected to be driven by robust growth in the construction industry. In 2017, the market was dominated by industrial and commercial applications. The rapid urbanization and favorable economic conditions in these regions have promoted the penetration of fiberglass duct wrap insulation. In addition, the increasing demand for energy-efficient HVAC systems is expected to drive the market growth.
The MicroLite FSK Fiberglass Duct Wrap is a GREENGUARD certified product. Its ECOSE technology uses a formaldehyde-free plant-based “binder” to give it shape and color. The product offers both thermal and acoustic insulation.
Fiberglass duct wrap can help prevent moisture buildup and reduce energy bills. It provides thermal and acoustic protection for HVAC ducts. It can be used in HVAC systems for both exterior and interior duct work. To install it, follow the SMACNA Duct Lining Installation Manual.
Cellulose duct wrap
Cellulose duct wrap offers several benefits for your HVAC system. It reduces heat transfer and provides effective thermal control. In addition, it also minimizes air infiltration. Because of its fire resistance and low dust content, this insulation is excellent for protecting the interior of your home. Moreover, it can reduce utility bills and improve indoor air quality.
It is made from recycled papers and contains up to 85% recycled content. Moreover, cellulose is mold and pest resistant. Its recycling content makes it an eco-friendly option for your HVAC system. As it is made from recycled paper, it’s 100% biodegradable. And if that’s not enough, cellulose duct wrap is also a cost-effective option for insulating your HVAC system.
Apart from offering excellent thermal properties, duct wrap helps you to reduce unwanted heat loss and condensation. This insulation product can be used for rectangular ductwork and is available in different sizes. Cellulose duct wrap contains glass fibers and a plant-based binder system. It is also useful for insulating sheet metal ductwork. It has a special backing that helps to reduce heat gain from moving air through the ductwork.
Elastomeric foam duct wrap
Elastomeric foam duct wrap offers several benefits, including the ability to prevent moisture from getting inside a building. It also prevents thermal loss, condensation, and sound transfer. Most manufacturers of closed-cell elastomeric foam offer a specially formulated white coating that is UV resistant. The coating requires two coats to provide complete coverage and should be reapplied every two to five years. It is not a substitute for white house paint. The coating expands with the elastomeric foam and prevents stress cracking and breakdown.
Elastomeric foam is available in open-cell and closed-cell versions. Closed-cell elastomeric foam is more expensive than open-cell foam, but it does not need an outer protective jacket. This type of foam is a good option if the owner project requires a non-fibrous material. This type of insulation can be used to line HVAC and refrigeration equipment and for ductwork. It is primarily selected for its ability to control condensation.
Elastomeric foam duct wrap is a great option for insulated ducts. It’s easy to install and has a closed cell structure that helps reduce heat loss and moisture transmission. It also offers excellent durability and is easy to clean. In addition, it doesn’t create fibre dust or odors and is antimicrobial.
Elastomeric foam insulation comes in rolls, tubes, and continuous sheets. Its closed-cell structure makes it suitable for a variety of duct types. Because of its closed-cell structure, it minimizes moisture wicking, dampens mechanical vibrations, and improves indoor air quality. Several manufacturers offer elastomeric duct insulation. Distributors include K-Flex, Aeroflex, and Armacell.
Glasswool duct wrap
Glasswool is a type of man-made thermal insulation material that traps air in a foam-like structure. It is similar to the properties of rock wool, Styrofoam, and other fabrics such as polar fleece and Gore-Tex. Its high acoustic and thermal properties help to improve interior air quality and generate significant energy savings. Another advantage is that it is reusable, making it an environmentally friendly option.
This insulating material is made of flexible glass fibres and a binder. The process of making glass wool creates pockets of air between the fibres, which gives it high thermal insulating properties. It can be manufactured in a variety of forms, such as rolls, tubes, and slabs, and can be sprayed or molded. It can be used to insulate piping, cavity walls, and curtain walls, and to act as a soundproofing material.
Glasswool duct wrap is an effective thermal and acoustical insulation blanket for ductwork. It is an excellent choice for interior and exterior sheet metal ductwork, as it adds a layer of protection and dampens sound. Its flexibility and ease of installation allow it to be used on both rectangular and round ductwork.
GlassRock duct wrap insulation is available in both low and medium density varieties. The low density version is used for acoustic insulation while the medium density version is suited for thermal duct insulation. It is odorless, lightweight, and flexible, and can resist changes in temperature. It is made of a sustainable plant-based binder system.
