Are you looking to improve the energy efficiency of your home?

One of the best ways to do so is by ensuring that your home has the proper insulation.

In this article, we’ll share easy to comprehend information about the most common  home insulation, including the benefits of insulation, the different types of insulation, and how to determine if your home needs insulation.

How home insulation works?

Insulating materials work by trapping pockets of air or other gases within their structure, which inhibits the conduction of heat through them.

The effectiveness of an insulating material is measured by its thermal conductivity (k-value), which indicates how readily it conducts heat, and its thermal resistance (R-value), which describes its ability to resist heat flow.

Higher R-values indicate better insulative properties.

Benefits of Home Insulation

Energy Savings

Insulation helps to keep your home warm in the winter and cool in the summer, reducing the amount of energy needed to heat or cool your home.

This can result in significant energy savings and lower utility bills.

Comfort

Proper insulation can help to maintain a consistent temperature throughout your home, which can improve comfort levels for you and your family.

Noise Reduction

Insulation can also help to reduce noise levels within your home by absorbing sound and preventing it from traveling through walls and floors.

Environmental Benefits

Reducing the amount of energy needed to heat or cool your home can also reduce your carbon footprint and help to protect the environment.

Types of Home Insulation and cost

There are several types of insulation available, each with its advantages and disadvantages. Here are the most common types of home insulation:

Fiberglass Insulation

Fiberglass Insulation
Fiberglass Insulation

Fiberglass insulation is one of the most popular types of insulation.

It is made of glass fibers and is available in batts, rolls, or blown-in forms. 

Fiberglass insulation is easy to install and is relatively inexpensive.

Example of whole house insulation cost: 

The cost of insulating a 1500 sq ft house with fiberglass insulation varies, ranging from $1,500 to $12,250 depending on factors like insulation thickness and region. To get an accurate estimate, it’s best to consult with a professional insulation contractor.

Cellulose insulation is made from recycled newspaper and other paper products. It is an eco-friendly option and is effective at reducing noise levels.

It is more expensive than fiberglass insulation.

Example of whole house insulation cost:

The cost of insulating a 1500 sq.ft house with cellulose insulation varies. Cellulose insulation can be installed using one of two techniques: blown-in (loose-fill or dense packed) or spray applied with moisture added. With blown-in insulation ranging from $0.50 to $1.50 per square foot. The average cost for an entire house’s attic is approximately $1,627.

However, it’s best to get a quote from a professional insulation contractor for an accurate estimate, as prices depend on the brand, quality, and region. Wet-spray cellulose costs between $0.60 and $1.80 per square foot, dense-pack cellulose costs $2 to $2.30 per square foot, and a bag of cellulose insulation typically costs around $30 to $40.
