5 Steps for Installing Properly Sealed Attic Insulation

Want to keep your home cool during the hot summer months and warm during the winter season? Installing properly sealed insulation is one of the best ways to do this. It helps to regulate the temperatures inside your home throughout the year and can even improve air quality. In this blog post, we’ll be discussing the five steps to installing properly sealed insulation.

What is an Attic Insulation?

It is a type of material that is placed between the rafters and joists in your attic. It acts as a barrier against air leakage, helping to regulate the temperature inside your home. Installing the insulation correctly ensures that no draughts or heat loss occurs, improving energy efficiency and comfort in your property.

Steps to Installing Properly Sealed Attic Insulation

Now that we know what it is, let’s take a look at the steps to installing it properly:

#1: Measure Your Attic

Before installing your insulation, it’s essential to measure the area of your attic. Before beginning installation, you should also note down any pipes or wires in the space. This will help you determine how much material you need for the job. This is essential to ensure that you achieve a correctly sealed attic.

#2: Choose an Insulation Type

Several attic insulations are available, including fiberglass batts, blown-in cellulose, spray foam, and rigid board insulation. Each type has its advantages and disadvantages, so it’s essential to research all your options before selecting the right one for your needs.

#3: Purchase Your Insulation Materials

Once you’ve chosen the right insulation type, purchase all the necessary materials to complete your installation. Make sure you have enough material to cover the entire area of your attic. Your budget will also be a factor in determining the type of insulation you can purchase.

#4: Install Your Insulation

It’s time to begin installing your insulation in the attic. The installation process may vary depending on the type of insulation you’ve chosen. If you’re using blown-in cellulose or spray foam, hire a professional to complete the job safely and correctly.

Professionals such as iFoam can help you with the installation process. They can also advise you on which insulation is best for your property and budget.

#5: Seal Any Gaps Around the Insulation

Once your insulation is installed, you should use caulk or spray foam to seal any gaps and cracks around it. This step is essential because it helps prevent air leakage, which could affect the temperature in your home.

These are just five steps to installing properly sealed insulation. Installing insulation correctly in your attic can help you save money on energy bills and make your home more comfortable year-round. Make sure you hire a professional if you’re unsure about the process!

Benefits of Properly Sealed Insulation

#1: Improved Energy Efficiency

Installing properly sealed insulation will help to regulate the temperature in your home, reducing the need for heating and cooling systems. This will result in lower energy bills and a more comfortable living environment all year round.

#2: Increased Home Value

Installing properly sealed insulation also increases the value of your property. Potential buyers are often more likely to purchase a home with good insulation, which ensures lower energy bills and more comfortable living conditions.

#3: Better Air Quality

Properly sealed insulation can help to improve the air quality inside your home. This is because the insulation will stop any draughts or leakage from outside, preventing dust, pollen, and other allergens from entering your property.

#4: Reduced Noise Levels

Installing insulation can help reduce noise levels in your home. This is because the insulation will act as a sound buffer, absorbing and dampening any sounds from outside or between rooms.


Overall, installing properly sealed insulations offers many benefits. It helps to improve your home’s energy efficiency, increases its value, and improves the air quality and noise levels inside. Investing in installing proper insulation is an essential step in making your home comfortable and energy-efficient.

Remember the steps to install attic insulation properly: assess the space, purchase materials, install your insulation, and seal any gaps. And if you’re unsure how to proceed, hire a professional to help!
