All You Need To Know About Attic Insulation: A Guide

Your attic is not just extra storage space; it's the one part of your home that can dramatically reduce your heating and cooling costs. With attic insulation, you can increase your home's energy efficiency, prolong the lifespan of your roof, and improve your family's health.

What Are the Different Kinds of Attic Insulation?

When it comes to insulation, the attic is one of the most critical parts that you should look into. With so many insulation options available, deciding which one is best for your home can be difficult. Here, we'll look at the most common insulation types used in attics and discuss their pros and cons.

  • Blanket insulation: This is typically made of fibreglass, rock wool, or cellulose. It is usually installed in batts or rolls and is available in different thicknesses and R-values. This insulation is relatively inexpensive and easy to install, making it a popular choice for many homeowners. However, it is not as effective as other insulation types, so it may not be the best choice if you live in a cold climate.

  • Blown-in insulation: This type is made of cellulose, fibreglass, or rock wool and is installed using a machine that blows the insulation into the attic. This type of insulation is more effective than blanket insulation, as it can fill in all the small cracks and crevices that blanket insulation may miss.

It also offers better coverage and is more energy efficient. However, it can be more expensive and challenging to install, so it may not be the best option for everyone.

  • Spray foam insulation: This is sprayed onto the attic walls and ceiling. It is made of polyurethane foam and is one of the most effective insulation types. It is also among the costlier options and requires professional installation, so it may not be the best choice for all homeowners. However, spray foam insulation is the way to go if you're looking for maximum energy efficiency.

  • Radiant barriers: These are reflective sheets installed on the attic walls and ceiling. They are designed to reflect heat away from the attic and prevent it from entering your home. This insulation is beneficial in hot climates but can be expensive and difficult to install.

What Are the Benefits of Attic Insulation?

Attic insulation helps keep stabilizes your home's temperature while also reducing energy costs. But attic insulation does more than save you money on energy bills. It can also help protect your home from mould growth, rot, and animal infestations.

Mould growth is a severe problem in many homes, and it can cause a variety of health issues, as well as damage to the structure of the home. Attic insulation helps reduce mould growth by keeping the temperature and humidity levels in the attic stable. This will help to prevent moisture buildup, which can lead to mould growth.

Rot can also be a serious issue in homes, especially in attics. Moisture buildup in an attic can cause wood to rot and weaken, making it more susceptible to damage from pests or weather. Insulating your attic can help to reduce the chances of rot, as it will help to keep the temperature and humidity levels stable.

Finally, attic insulation can help to prevent animal infestations. Insulation helps keep the attic's temperature and humidity levels stable, making it less attractive to animals looking for a warm, cozy place to nest.


Attic insulation is a wise investment for any homeowner, as it can help save money on energy bills while protecting your home from mould growth, rot, and animal infestations. If you're looking to improve your home's energy efficiency, be sure to consider the benefits of attic insulation.
