Insulation, in relation to thermal purposes, is the process of slowing conductive heat flow and–to a lesser extent–convective heat flow. Simply put, it is the process of reducing heat flow.

Now that you understand what insulation is about, attic insulation is the process of insulating the attic in your home. The point of insulating an attic is to keep the rooms below cool in hot weather or seasons like summer, and keep the rooms warm in seasons like winter.

Useful Information


Properly Insulating your attic will help you save on your energy Bill. Insulation will stop hot air from entering your home on hot days, and  will stop Warm air escaping on cold days.

Types of Attic Insulation

Insulating your attic properly is important as you get to save money on your heating and cooling bill. When your attic is properly insulated, air flow to other rooms in the house is regulated so that your house stays warm in cold weather and cool in hot weather.

Ways to insulate your attic Include:

  • Loose-fill Cellulose Insulation
  • Loose-fill Fibreglass Insulation
  • Spray-Foam Insulation
  • Fibreglass Batt-Insulation
  • Dense Pack

Attic Applications

Cellulose Lose-fill Insulation

This is made from fibres that are made from recycled post-consumer paper that is treated with boric acid for insect control and fire resistance. Now, while it necessarily doesn’t create an air barrier, it is very dense so that it stops moist air from moving around. 

Fibreglass Loose-fill Insulation

This method of insulation is widely used in new construction homes as it has gained popularity over the years. These fibres are packaged in bags and then blown in place to the density and depth of your choice. You’d have to use a special machine for this process so you either buy or rent one. Fiberglass is known to be itchy and can be irritating so you want to be careful while using it.


Spray-Foam Insulation

This is easily the best insulating type in terms of its performance but also the most expensive. There are two types of spray foam which include; closed cell and open cell. If installed properly, both insulation types will make for an amazing air barrier as they fill all areas and when air flow has been blocked, heat can’t be transferred through convection.

Fibreglass Loose-Fill 

These are flexible insulation materials, which are often packaged in rolls that come in different thicknesses and widths. This insulation method is inexpensive but not very effective as it doesn’t totally block airflow.
