Best Kinds of Insulation for Your House

Best Kinds of Insulation for Your House

Having a shelter is a basic need, and you want to ensure that your shelter can provide adequate support against changing climates. Your house needs good insulation to keep you from toasting during the summer and freezing in the winter.

The question is: what kind of insulation do you need?

Check out the best insulation you can install in your house below.

Spray Foam Insulation

Spray foam insulation uses liquid polyurethane to fill in gaps and cavities between walls. It has the capacity to expand, after which it hardens and forms a solid foam that has some of the highest R-values of any insulation.

This means it functions well in resisting heat flow. However, spray foam does come with its fair share of disadvantages

It’s tricky to install and tends to be expensive. When not correctly installed, the material can also lead to more trouble such as water damage, missing cavities, and potential shrinkage. 

Fibreglass Insulation

Fibreglass is another insulation material that is known for its exceptional capacity to reduce heat transfer. It’s also fire-resistant and easy to install.

Homeowners can even do the installation themselves if they have some DIY knowledge. This can drive down labour costs because you don’t need to hire a contractor.

At the same time, the material itself is less expensive than spray foam. 

However, it is also a bit less effective than spray foam particularly when it comes to colder climates. It can also be hazardous if mishandled or inhaled.

Beyond that, you may also need to pull down walls before you can begin the installation.

Mineral Wool Insulation

Mineral wool has a higher R-value compared to fibreglass and is also known for having high density. Aside from insulation, using this material can have the added benefit of soundproofing your home to an extent.

It’s often made from 30% recycled materials and offers superior fire resistance. The hydrophobic material also resists the development of mold and mildew. 

Meanwhile, it is sturdier than fibreglass and does not require staples or wire to hold it up.

However, it is a bit more expensive than fibreglass and does not have many options in terms of sizes or shapes. It is also fairly difficult to install.

Cellulose Insulation

If you want a more eco-friendly insulation material, cellulose insulation is your best bet. This material is derived from plant sources but functions similar to spray foam.

It settles into gaps and cavities in walls or attics and is easy to fill in without tearing down walls.

Cellulose insulation is also one of the more affordable options and can repel pests like insects or vermin. 

On the flipside, cellulose also tends to settle or pack down over time. This creates thermal bridges that transfer hot and cold air.

At the same time, it takes a long time to dry when it soaks up moisture. This increases the chances of developing mold or mildew. 


Insulation is important in reducing your heating and cooling costs, but it’s also vital for your comfort. While getting insulation installed can be tricky and expensive, you have a lot of options to choose from if you want to get quality insulation to fit your budget.

Spray foam, fibreglass, mineral wool, and cellulose are some of the best materials for insulation. Each has its own advantages and disadvantages, so doing your research is important before you jump the gun.

If you’re still not sure what to pick, you can ask your insulation contractor for their opinion on what fits your house best. Find the best insulation companies in Edmonton here
