Thermo Ply Red vs Green: Exploring the Key Differences

In terms of using engineered wood for sheathing, the use of thermo-ply is only increasing. But people get confused as there are different types of thermo-ply available in the market. Because these types slightly vary from each other, people want to know the comparison between thermo-ply red vs green.

Well, thermo-ply red and thermo-ply green have almost all the same characteristics as they belong to the same category. Yet, there are some differences that separate them from each other. For many ordinary people, this might not seem a big deal. But people who care about little details find these differences remarkable.

The Primal Differences

The first and foremost difference between thermo-ply red and thermo-ply green is in their color. The former is evidently red in color and the latter is green and you will get a connection with nature more subtly with the green thermo-ply engineered wood. Besides, thermo-ply green can provide a light sheathing on the roof which is convenient for installation. But that does not mean thermo-ply red offers heavy sheathing. It comes with standard weight which is also convenient.

Then again, these thermo-ply boards don’t come with the same composition. Thermo-ply red is composed of woven fabric of polypropylene whereas thermo-ply green is of polypropylene and polyethylene. That’s why the former offers more waterproofing tactics while the latter offers more durability.

These are some primal differences apart from their numerous similarities. There are more differences that might draw your attention. We are going to reveal all these in our article with this compact comparison table. So, stay tuned.

Difference between Thermo Ply Red and Green Sheathing

There are many similarities between thermo-ply red and thermo-ply green as they are both composite panels. Besides, they both can control the moisture of the weather and keep the interior warm and healthy. Thermo-ply engineered woods have this special offering that they don’t allow the water to penetrate the sheathing and ruin the interior and lower the longevity of the sheathing.

This is the prominent difference between thermo-ply green and thermo-ply red. This color difference works both literally and metaphorically. The former, for example, symbolizes the closeness with nature because of the green color and the latter symbolizes safety.

That means thermo-ply red offers more safety in the literal sense. Also, the effectiveness of the construction with the help of thermo-ply red is way better.


Weight matters since people need to deal with the installation of these panels. That’s why the lighter the weight, the better. In this case, thermo-ply green offers a very lightweight structure. For this reason, many people go for thermo-ply green sheathing.

But, even though thermo-ply red is not as lightweight as thermo-ply green, it has a standard weight. That’s why it will not put much bad impact while installing it.

Prominent Advantages  

Many people select one composite panel seeing the better advantage. Thermo-ply red is way more active in controlling water and works as an air barrier more solely. It can prevent moisture from penetrating deep into the sheathing and also alerts when it catches fire.

Well, thermo-ply green is also able to provide you with all these advantages but not as effectively as thermo-ply red. People bring this thermo-ply green more because it provides utter durability and strength. The longevity it provides is its best performance ever.


These two thermo-ply composite wood are made of different materials. Even though many materials are almost the same, there are some primal materials that make thermo-ply green and thermo-ply red different from each other.

For example, thermo-ply red has polypropylene and polymer agents as its top coat on a prominent basis. For this reason, it offers the best waterproofing formula ever. On the other hand, thermo-ply green gains its strength from the agents of polyethylene along with polypropylene.

Both thermo-ply green and thermo-ply red contribute to the sheathing. You can use them for roofing, sheathing, and even for flooring. But people mostly use thermo-ply green for exterior sheathing and thermo-ply red for interior flooring.


From the expense, it can vary from installation to buying the composite wood. But from the general view, thermo-ply green is more expensive than thermo-ply red. Because these are premium construction materials and more or less have the same high-quality feature, you cannot have them in a cheap range. Besides, thermo-ply green is more powerful and eco-friendly and thus requires more money.

So, which one is better?

We cannot downgrade any of these composite woods as both thermo-ply green and red have their discrete top-notch feature to offer. So, you can have them both and use them for all kinds of sheathing processes.

And if you want to be specific, then adopt thermo-ply green for its durable and eco-friendly features. But if you live in a damp area where controlling the moisture is more important then go for thermo-ply red.
