4 Duct Board Alternatives You Can’t Miss In 2022

It’s frustrating! 

It’s really frustrating when you’re working with fiberglass and skin irritation occurs. As if that’s not enough, you can experience a bit of respiratory irritation as well. But, why does this happen? 

Duct boards can emit tiny broken glass materials. Even though these materials are tiny and loose, they’re sharp enough to pierce the skin. So, they can cause discomfort to the uncovered skin and nasal passages. 

Many people wonder if there’s a duct board alternative?

Yes, there are 4 alternatives to the duct board. In fact, some of these alternatives work even better than the duct board itself. By using these four alternatives, you can create a safe environment for yourself and your home.

That’s just the tip of the iceberg. To know about these alternatives in detail, you’ll need to read the rest of the guide below. Don’t worry, we’ve kept things simple for you. 

Sounds interesting? Let’s not waste any more time- 

Why Do You Need A Duct Board Alternative? 

We get it, you’re here looking for the alternative of duct board. However, duct board installation does save up the cost. Moreover, it even works at saving up energy as it’ll trap more heat in winter. 

And, that’s not all, it even works at keeping heat away at the time of summer. Then, why should you look for alternatives? Well, we have the reasons why working with fiberglass isn’t a viable option. Let’s find them out- 

Reason #1: Causing Skin Irritation

When you’re working with fiberglass, it can cause irritation to the uncovered skin. Here, micro broken glass materials can easily cut into the skin. As a result, they can cause skin itching and discomfort. 

Even though these materials don’t cause any long-lasting skin risk, they can provide a slight level of discomfort. 

To tackle this situation, some install additional vents in order to maintain the airflow. But, that doesn’t resolve the situation as the micro-glass materials can pierce anytime. 

Reason #2: Possessing Cancerous Cells

Normally, fiberglass emits synthetic materials like styrene. And, it’s found from the “National Toxicology Program” that it can cause cancer. Here, fiberglass doesn’t directly cause cancer cells. 

However, the report suggested that the material styrene can cause cancer. So, it possesses some threats to the homebuilders working with fiberglass. 

Reason #3: Causing Respiratory Irritation

Fiberglass can emit loose insulation fibers. As these materials are tiny in nature, they become airborne quite easily. Being airborne, they can enter the body when you inhale the air. 

By now, we’ve provided any idea about how these tiny materials can pierce through the skin. And the same happens here. These tiny materials can pierce into the internal organs too. 

As a matter of fact, they even penetrate into the tissues as well. So, they can cause respiratory irritation along with skin irritation. 

Then again, they don’t cause permanent damages. But, they’ll cause discomfort to the nasal passages and cause irritated throats too. As if that’s not enough, they can cause irritation in the lungs as well. 

4 Easy Duct Board Alternatives

Well, we’ve shown why you’ll need a fiberglass insulation alternative in the first place. Even though fiberglass insulation saves up energy, it can cause some short-term skin risks

But, you can always choose the alternatives of using duct boards. In fact, some of these alternatives can work even better. That said, let’s check them out- 

Vinyl Insulation

Vinyl insulation comes in the same form factor as fiberglass. Here, the insulation comes wrapped up in the form of a roll. So, you can simply wrap this insulation material over the duct. 

Moreover, you can even seal them tightly by using tape. Even though it doesn’t look appealing, it’ll still do the work. 

However, it does have the reputation of letting hot air escape. Generally, it allows air to escape from the material’s fold. Here, many people try to caulk over the duct in order to stop hot air from leaking. But, taping the surface would do. 

And, if you want, below are our top-favorite tapes that’ll allow the vinyl to stick tightly to the surface:


In the end, vinyl insulation is a cheap option. So, you can consider it to be a strong alternative to fiberglass. 

Wood Insulation

Wood insulation is a more conventional method of keeping your home warm. Normally, the process is conducted when a layer is used in order to protect the cabin from drafts. 

Basically, you’ll have to tape or caulk the wood around the duct in order to secure them tightly in place. 

Here, the main advantage of using this alternative is that it’s environmentally friendly. And, it can be a bit cheaper if you have trees available around you. 

Green Themes

In the previous alternative, we’ve discussed a greener alternative. However, if you’re not comfortable working with woods, there are other options as well. Out of them, the most common is Cellulose foam. 

Here, this foam is made of recyclable materials. So, you can wrap them tightly in order to provide a bit of insulation. 

On the other hand, you can use straws and even older newspapers. Just place them tightly around ducts and seal them with caulking. 

Urethane Foam

Using urethane foam can be a modern-day alternative to fiberglass insulation ducts. In fact, it’s even preferred by homebuilders and inspectors. But, why? Well, the foam material hardens quite easily from the can.

And, you can just pour the foam into hard-to-reach areas and it’ll harden itself. By doing this, you can easily reach surfaces easily. Another advantage of this material is that it’ll cover more area and can secure them tightly as well.

However, the only drawback of using this material is the cost factor. Compared to the duct boards, this is way more expensive. And, the cost will only go higher when you’ll need further repairs in the future. 

Besides, living inside homes can be uncomfortable as the materials need time to harden up. So, the time required can cause a bit of discomfort. And, you can’t even carpet over flooring at this time as well. 


Question: What material is better as ductwork?
Answer: Well, sheet metal can be one of the best materials for ductwork. These sheets are lightweight and easy to install. Moreover, they don’t cause mold formation as they don’t have pores on the surface. 

Question: What duct is the most efficient?
Answer: Round duct is considered to be the most efficient out of all the ducts. Here, the superior airflow resistance and air leak make these ducts efficient. Even though the shape of these ducts causes a problem as they won’t fit in tight space. But, you can always convert them to oval and rectangular shapes easily. 

Question: Do the ducts require proper sealing?
Answer: Yes, ducts do require proper sealing. A properly sealed duct ensures comfort and saving of energy all year round. So, you’ll be able to save up on the electricity bills more often than usual. 

Question: How long duct seals last?
Answer: Normally, duct seals are designed to last for almost 15 years. However, they can fall for numerous reasons. Other than that, they’re expected to last as the other duct systems. 

Question: What’s the cost to replace ductwork?
Answer: Normally require 35-85 feet of ductwork. And, the per foot cost can go up to $36-$54. So, the average cost of replacing ductwork may end up at $1000-$5000.
