Which Type of Insulation Is Right for You?

Whether it is for new construction or for a retrofit, understanding the different insulation options can help you to enjoy energy savings in your home. This article discusses some of the attributes of the common insulation options that you can choose from.

Loose Fill Insulation

Loose fill insulation is at times called blown-in insulation. This type of insulation is commonly made from cellulose or fibreglass. Loose fill insulation is good for hard-to-reach places, such as wall cavities and attic floors. However, blown-in insulation can reduce in effectiveness once it settles after installation. Settling can be minimised by the use of adhesives during the installation process. Care should also be exercised to avoid placing heavier insulation materials, such as blankets, on the loose fill. Loose fill insulation can be used for new construction or retrofit situations.

Insulation Blankets

Insulation blankets are available in rolls or batts. They are made from fibreglass and are precut to fit into the gaps between floor joists or wall studs. Insulating blankets are usually ideal for new construction because sheetrock can be placed on top of them. It may be disruptive to use them during retrofit projects because the installation may damage finished walls.

You should also remember to buy insulation blankets that have vapour barriers. This is because moisture can quickly render the insulation ineffective if it penetrates the sheets/blankets. A professional can study your location and advise you on which side to place the vapour barrier.

Spray Foam Insulation

Spray foam creates a dense barrier to the transfer of heat because it expands once it has been applied. This barrier is resistant to moisture ingress. It is also resistant to attacks by mould. Like blown-in insulation, spray foam is good for use in hard-to-reach locations, such as wall cavities and attic floors. The most noticeable downside of spray foam is that it is the most expensive variety of insulation. Spray foam can be used during new construction or for retrofit purposes. You should also remember that it comes in two versions, namely, open-cell and closed cell foam spray. The closed cell variety is denser and may provide better resistance to heat transfer.

Each home has its unique attributes that may make one type of insulation more suitable in comparison to others. It is therefore advisable for you to talk to an insulation expert who will evaluate your situation and recommend the best insulation option for your needs.
