Differences Between Denim Insulation and Fiberglass Insulation
Denim insulation and fiberglass insulation are perfect candidates for attic insulation and wall insulation, and they have been used extensively in the industry due to their versatility and quality. Both denim insulation and fiberglass insulations are effective insulators. Still, there are key differences in many aspects, including the material, the method of installation, the level of insulation provided, the cost of installation, and much more.
Listed below are the key differences between denim insulation and fiberglass insulation.
Denim insulation has an NRC rating of 1.13, and the STC rating is 45
NRC rating of fiberglass is 0.9, whereas the STC rating is 39
The R-Value of denim insulation is about 3.5/inch and is very good for insulators.
Fiberglass insulation has a R-value of 2.5/inch
The cost of installation of denim insulation is higher and is less economical.
The cost of fiberglass insulation is about half of that of denim insulation and is more economical of the two.
Denim insulation is denser and can provide much more insulation for the same volume of material.
Fiberglass insulation is less dense and may need layers to provide the same level of result as denim insulation.
Both denim and fiberglass insulation have their advantages compared to the other. This provides the informed user with a lot of freedom to use them to select the perfect insulation for their home. On the one hand, Denim insulation has higher insulation properties inherently but costs more than fiberglass insulation, making it an expensive option.
Denim insulation is made up of old recycled cotton and denim fabrics. It is a practical, recycled, eco-friendly approach towards insulation and can be used almost anywhere, including wall cavities, floors, attic insulation, wall insulation, etc.
Before it reaches the market, the insulation is treated with boric acid, which makes it resistant to fire, molds, etc. This is evident because it has a class A fire rating. Denim insulation also has a high R-value, STC rating, and NRC value, making it an ideal solution for your home insulation projects.
Let us closely analyze the pros and cons of denim insulation.
- Denim insulation is fire resistant.
- It can also withstand/prevent the growth of mold and mildew due to boric acid treatment.
- Denim insulation has a high R-value of 3.5/inch
- It has a high STC rating of about 45
- It doesn’t contain any volatile organic compound in it.
- It is not known to have any side effects for the users and is safe for kids.
- It has high density and can provide amazing insulation to your home.
- In most use cases, the thickness of denim insulation can be lower than their claims and can affect the R-value of the material.
- If it is compressed at any point in time, it can be hard to be fluffed up again, and this can, in turn, affect the R-value and the insulation properties of the material.
- It isn’t water-resistant.
- It is costlier than fiberglass insulation.
- It can trap dust in them and may need maintenance.
As the name suggests, fiberglass insulation contains fine threads of glass, and it can drastically reduce energy consumption by providing proper insulation to your home. It is also an environment-friendly product as the main constituent of the material is recycled glass.
In addition to thermal insulation, fiberglass is an amazing soundproofing material, providing the user with multiple utilities.
Many varieties and combinations of fiberglass insulation are available in the market, including faced insulation, unfaced insulation, blown-in insulation, batt insulation, etc. These vary in insulation properties and can be chosen according to insulation requirements and budget.
Let us look at the pros and cons of fiberglass insulation.
- It is economical.
- It is lightweight and hence won’t exert much stress on the wall.
- It is fire-resistant.
- Available in different forms such as faced insulation, unfaced insulation, blown-in insulation, batt insulation, etc., and can be used according to one’s requirement.
- Has excellent R-values, NRC value, and STC rating.
- It has a lot of volumes, as it is fluffy.
- The R-value of fiberglass insulation can vary according to the shape and thickness of the material.
- It is comparatively less dense than denim insulation.
- It can cause itchiness in some users at the time of installation.
- It is not water-resistant.
