A protected duct liner is a material infused into a duct to avoid air leakage, condensation, and energy loss. If you need a duct liner to circulate the warm or cool air, call our agents and book your duct liner installation. However, you require different types of duct liners, so make sure you explain all your needs to get the perfect liner.
Different Types of Protected Duct Liner
The role of a duct liner is to circulate warm and cool air throughout to prevent air leakage and energy loss and to prevent sound absorption from airborne and structure-borne HVAC noise.
Fiberglass Duct Liners
Flexible fiberglass is among the most commonly used liners. They are coated to provide durability and resistance to contaminants.
- Reinforced facing for moisture and microbial resistance.
- Anti-mold and anti-mildew treatments.
- It can include a vapor barrier to prevent moisture absorption.
It is used in commercial and residential HVAC systems to reduce noise and enhance thermal insulation.
Elastomeric Foam Liners
These liners are made of closed-cell elastomeric foam, providing excellent thermal and acoustic insulation.
- Non-porous surface resists moisture and microbial growth.
- High resistance to chemicals and physical damage.
- Fire-resistant and meets safety codes.
It is perfect for areas that require hygiene standards, such as hospitals and laboratories.
Rubber Duct Liners
The internal duct liner comprises rubber-based materials that provide robust insulation and noise control.
- Highly durable and resistant to mechanical damage.
- Resistant to oil, grease, and other contaminants.
- Smooth surface for easy cleaning.
They are often used in industrial and high-traffic areas.
Anti-Microbial Duct Liners
These are treated with antimicrobial agents to inhibit the growth of bacteria, mold, and fungi.
- Actively reduces microbial growth.
- Improves indoor air quality.
- It helps in reducing the need for frequent cleaning and maintenance.
The anti-microbial liners are used in healthcare, food processing, and high-humidity environments.
Composite Duct Liners
It combines multiple materials, such as fiberglass and polymer, to leverage the benefits of each.
- Multi-layered for enhanced thermal and acoustic properties.
- Resistant to microbial contamination and wear.
- Often includes fire-retardant materials.
These are suitable for versatile HVAC system requirements.
Polymer-Coated Duct Liners
Fiberglass or other base materials coated with polymer to enhance durability and protection.
- Excellent resistance to moisture, microbial growth, and abrasion.
- Easy to clean and maintain.
- It provides a smooth surface to minimize dust accumulation.
These coatings are used in commercial and institutional settings, especially where air quality is critical.
What are the Pests Found in Internal Duct Liners?
Rats and Mice
However, rodents and mice like to crawl in tight spaces. They are often found in the duct liner and can damage your HVAC system.
Raccoons and Squirrels
They can chew the ductwork and vents, allowing warm and cool air to escape through holes, increasing usage and bills.
Insects
Meanwhile, dark places are ideal for insects to hide out, which can cause damage, yet dust mites also trigger attacks and other diseases.
Symptoms of Pests in Your Duct Liners
- If there are scratches on the vent walls.
- Chewed ducts and valve.
- Dropping of mice or other pests.
- Materials, like nesting or feathers.Â
How to Keep Pests Out of Your Duct Liners?
To protect your duct liner, you must know several ways to prevent pests.
- Check for ducts for gaps, holes, or loose connections.
- Use mastic sealant or metal tape to seal any openings.
- Clean your home regularly to eliminate food crumbs and debris that attract pests.
- Ensure to replace air filters according to the manufacturer’s recommendations to maintain airflow and prevent pest infiltration.
- You must use a dehumidifier to maintain optimal indoor humidity.
- Use pest repellents like essential oils.
- Call our pest control experts to inspect and treat your duct liner installation if the infestation persists.
How Much is the Price for a Used Duct Liner?
The price of protected duct liners varies depending on the type and brand, such as thickness, size, and additional features.
- Fiberglass Duct Liners: $0.75 to $2.50 per square foot
- Antimicrobial or Coated Duct Liners: $1.50 to $4.00 per square foot
- Elastomeric Duct Liners: $1.00 to $3.50 per square foot
- Polyethylene Duct Liners: $0.85 to $2.00 per square foot
Frequently Asked Questions
What is the use of duct liners?
The duct liner lines the inside of HVAC ducts and the air distribution system, which handles air and helps to reduce the transfer of acoustic energy. You can call our agents to install the duct liner.
Which material is used for duct leakage?
Duct Matic and mastic tape are designed for HVAC applications and are better methods for durability and long sealing. These are directly applied to connections and seams on the internal duct liner.
How long does a duct seal last?
However, they are not permanent, practical, and high-quality materials if used longer. We provide the best-protected duct liner so you can buy it for the best price. Call our agents and book yours soon.
