How Much Does Internal Wall Insulation Cost?
Internal wall insulation is an effective way to make any home more comfortable and energy efficient. But how much does it cost? Let’s explore this question in more detail.
- Fiberglass Batting Insulation
Fiberglass insulation is a popular choice for internal wall insulation because of its affordability and ease of installation. Typically, fiberglass batting insulation costs approximately $0.88 to $1.64 per square foot. This type of insulation comes in pre-cut batts placed between the studs of your wall.
This material is a cost-effective option for homeowners who want to improve the energy efficiency of their homes with less money. However, fiberglass batting insulation is not as effective as other materials in reducing heat transfer.
This means that it may provide different energy savings than other types of insulation. Additionally, fiberglass can be itchy and uncomfortable to work with, posing a health risk if inhaled.
- Spray Foam Insulation
This insulation is one of the most effective choices for reducing heat transfer, and it’s also one of the most expensive. Depending on the project, the approximate cost of spray foam insulation runs between $1,284 and $3,741.
Due to the specialized equipment and training required for installation, the cost is high. Despite the higher cost, spray foam insulation offers several benefits.
For example, it offers a tight air seal, reducing the air that can leak in and out of your home. This not only improves your home’s energy efficiency but also reduces drafts and improves indoor air quality.
- Blown Cellulose Insulation
It is made from recycled paper which makes it environmentally friendly. In general, blown cellulose insulation costs around $1.00 to $1.50 per square foot.
This type of insulation is blown into your internal walls using specialized equipment, filling in gaps and providing a layer of insulation. However, it’s not as effective at reducing heat transfer as spray foam insulation.
Additionally, the installation process will be messy and time-consuming and require some patching and repairs to the internal/external walls after installation.
