What Is Sheathing?

Sheathing is a layer of material that is used to cover the exterior walls of a building, providing a barrier that protects the home from the elements. This layer is also essential for insulation, as it helps to keep heat and cold from escaping the home, improving its overall energy efficiency.

What Is Densglass Sheathing?

Densglass sheathing is a type of fiberglass-reinforced gypsum board that is commonly used for home insulation. This material is known for its durability, moisture resistance, fire resistance, and energy efficiency.

Types Of Densglass Sheathing

There are three different types of Densglass sheathing available on the market: Densglass Gold, Densglass Silver, and Densglass Shaftliner. Each of these options has its own set of features and benefits, so it’s important to carefully consider which type is right for you.

1. Densglass Gold

Densglass Gold is a high-performance sheathing material that is designed to withstand even the harshest of conditions. It is a moisture-resistant material that is also fire-resistant, making it a popular choice for use in homes located in areas that are prone to hurricanes, earthquakes, or other natural disasters.

2. Densglass Silver

Densglass Silver is a more affordable option that is designed for use in a variety of different applications. It is a versatile material that is moisture-resistant and fire-resistant, making it a great choice for homes located in areas with moderate climates.

3. Densglass Shaftliner

Densglass Shaftliner is a specialized type of Densglass sheathing that is designed for use in elevator shafts and stairwells. It is a fire-resistant material that is also moisture-resistant, providing excellent protection in these areas of the home.

Demerits Of Densglass Sheathing

While there are many benefits to using Densglass sheathing, there are also some potential drawbacks to consider. Some of the main disadvantages include its cost, weight, and installation difficulties.

1. Cost

Densglass sheathing is typically more expensive than other types of sheathing materials, such as plywood. While the initial cost may be higher, the long-term benefits of Densglass sheathing, including its durability, moisture resistance, fire resistance, and energy efficiency, can help to offset the cost over time.

2. Weight

Densglass sheathing is also a heavier material than other types of sheathing, making it more difficult to handle during the installation process. This can increase the time and labor required for installation, which can drive up the overall cost of the project.

3. Installation Difficulties

Finally, the installation process for Densglass sheathing can be more difficult than other types of sheathing materials. This is because the material is thicker and heavier, and requires specialized tools and equipment to install correctly.

What Is Plywood?

Plywood is a type of sheathing material that is made from thin sheets of wood that are glued together. This material is commonly used for home insulation, as it is an affordable and versatile option that can be used in a wide range of applications.

There are several different types of plywood sheathing available, including sanded plywood, pressure-treated plywood, and OSB (oriented strand board). Each of these options has its own set of features and benefits, so it’s important to carefully consider which type is right for you.

Types Of Plywood Sheathing

There are two types of plywood sheathing:

1. Softwood

This type is made from spruce, pine, or fir. It is the most common type of plywood sheathing and is typically used for exterior walls, roofing, and floors.

2. Hardwood

This type is made from birch, maple, or oak. It is less common than softwood plywood sheathing and is typically used for interior walls and floors.

Plywood comes in different grades depending on the type of wood used and what kind of glue is applied. With so many different grades available, it can be difficult to know which one you should use for your project. The common types are:

• Oriented Strand Board (OSB)

This type is the cheapest and has a higher R-value than other grades. It also does not require any special finishing material because it comes pre-treated with wax to reduce moisture absorption. However, OSB plywood cannot be used for roofs since water can seep through the joints of the wood.

• Marine Grade

This type is designed for use in damp or wet conditions. It has a waterproof glue that allows it to stay intact even when exposed directly to water (ideal for boats). However, this plywood cannot be used with certain types of insulation like Densglass sheathing because the moisture from the wood will cause mold and mildew.

• Structural Grade (LVL)

This type is designed to be used as beams or joists in homes because it has a high load-bearing capacity and an increased stiffness rating. This plywood does not come pre-treated like the other types; instead, you will need to apply your own waterproofing treatment before using it.

Merits Of Plywood

There are several key benefits to using plywood sheathing for your home insulation needs. These include its affordability, versatility, and ease of installation.

1. Affordability

One of the biggest advantages of using plywood sheathing is its affordability. This material is typically less expensive than other types of sheathing, making it a great choice for homeowners who are working within a tight budget.

2. Versatility

Plywood sheathing is also a versatile material that can be used in a wide range of applications. This material is commonly used for flooring, walls, and roofing, making it a great choice for homeowners who want a versatile and multi-functional sheathing material.

3. Ease of Installation

Finally, plywood sheathing is relatively easy to install, making it a great choice for DIY homeowners or for those who are working with a limited budget. This material can be cut and drilled easily, making it simple to install and customize for your specific needs.

Comparison – Densglass Sheathing Vs Plywood

 

When comparing Densglass sheathing and plywood, there are several key factors to consider. These include cost, weight, installation difficulties, moisture resistance, fire resistance, and energy efficiency.

1. Cost

Densglass sheathing is typically more expensive than plywood, although the long-term benefits of Densglass sheathing, including its durability, moisture resistance, fire resistance, and energy efficiency, can help to offset the cost over time.

2. Weight

Densglass sheathing is a heavier material than plywood, making it more difficult to handle during the installation process. This can increase the time and labor required for installation, which can drive up the overall cost of the project.

3. Installation Difficulties

The installation process for Densglass sheathing can be more difficult than for plywood, as the material is thicker and heavier and requires specialized tools and equipment. However, plywood sheathing is relatively easy to install, making it a great choice for DIY homeowners or for those who are working with a limited budget.

4. Moisture Resistance

Densglass sheathing is more moisture resistant than plywood, making it a better choice for homeowners who live in areas with high levels of rainfall or humidity. Plywood sheathing, on the other hand, is sensitive to moisture and can be damaged over time by exposure to water or other types of moisture.

5. Fire Resistance

Densglass sheathing is designed to be fire-resistant, making it a better choice for homeowners who live in areas with high fire risk. Plywood sheathing, on the other hand, does not have this feature and is not as effective at protecting against fire.

6. Energy Efficiency

Densglass sheathing is more energy efficient than plywood, as it helps to keep heat and cold from escaping the home and improving the home’s overall energy efficiency. This can lead to lower energy bills over time and a smaller carbon footprint.

Densglass Sheathing Vs Plywood: Applications

Plywood Sheathing

Because of the low cost, availability, and ease of installation, plywood is ideal for temporary fixes. This includes emergency repairs or construction that will take less than six months to complete.

If you are planning on making a long-term investment in your home’s insulation by using Densglass sheathing instead of plywood, it would be wise to do some research first.

Densglass Sheathing

Densglass sheathing is the perfect choice for permanent installations since it will not warp, deform or degrade when exposed to extreme weather conditions. This makes it ideal for use on homes that are located in high-risk hurricane areas (e.g., Florida, Texas).

It can also be used with other insulation products including spray foam and cellulose fibers, allowing you to create a customized insulation system for your home.
