Home Insulation Solutions

Certainly, you’ll be reminded by those drafty spots in your home that the cold weather is here. I thought this would be a great time to look at the four main types of home insulation products on the market that are used in various parts of the home: fibreglass, mineral wool, cellulose, and spray foam.


Each of these has different qualities, so I hope this information will help you choose your materials wisely.

Fibreglass insulation


Made from glass cullet and other raw materials that are melted and spun into fibres, these resemble the texture of wool. (Fibreglass insulation, pictured)


Commonly used in attics, walls, floors, crawl spaces, high ceilings, and basements, these come in batts, rolls, or loose-fill forms.


Mineral wool insulation (rock, stone or slag wool)


Made from rock, blast furnace slag, and other raw materials that are melted and spun into fibres and which have a wool-like texture, mineral wool comes in batts, rolls, or loose-fill forms. 


Like fibreglass, it is also used throughout the house – in side walls, attics, floors, crawl spaces, cathedral ceilings, and basements. (Mineral wool, pictured)


Stone and slag wool insulation are comprised of basically the same raw materials, produced in the same ways, and producing similar performance qualities. The main difference is in the specific volumes of raw materials used in the production of each product.


Cellulose insulation


Comprised mainly of cellulose fibres usually made from paper, paperboard stock, or wood, and made with or without binders, cellulose is chemically treated to be fire-resistant, however, the application process is not standardised, and there is evidence of the fire resistance wearing off over time.

Spray foam insulation


This chemical-based insulation is mixed on-site by insulation professional contractors to create a foam, and applied with a sprayer in attics and wall cavities. 


There are two main types of spray foam insulation – open cell and closed cell. The properties of each are moderately different. (Spray foam insulation, pictured)


Consulting with an experienced contractor will make a huge difference when it comes to battening down the hatches in your home to ensure you keep the hot air in and the cold air out, at least in the winter.
