What is the Difference Between Spray Foam Insulation and Fibreglass?


Spray Foam Insulation

Contractors, property managers and homeowners have a range of choice when it comes to insulation products, and that can make things a bit confusing. You may be wondering which popular insulation material is best for your building, your region and your budget—so NFW would like to help clarify the difference between spray foam insulation and fibreglass. These are the most commonly used insulation materials in Alberta and many other regions. 


Fibreglass

Fibreglass, created from fine strands of plastic coated with glass fibre, has been used as an insulation material since the 1930s. Today, it remains one of the most common materials for ceiling and floor insulation globally, offering an R-value of about 2 to 3 per inch of thickness. The R-value measures an insulating material’s resistance to heat flow, calculated by comparing the temperature difference between two sides of the insulator. 

Despite its relatively low R-value, fibreglass insulation is popular due to its affordability and accessibility. Its cost-effectiveness has ensured its enduring presence in the insulation market. Additionally, the ease of installation means that almost any construction company can handle fibreglass insulation, and many handy homeowners have successfully installed it themselves. Of course, home installation must be completed using personal protective equipment to prevent the irritating fibres from entering the nose, throat and eyes. Even prolonged skin contact with fibreglass is uncomfortable, which is one reason many insulation installers are glad to leave it in the past. 


Spray Foam Insulation 

Spray foam insulation comes in two main types used in residential, commercial, and industrial properties: open-cell and closed-cell. Closed-cell spray foam is denser and offers the highest R-value of about 7, while open-cell spray foam has an R-value of 3+ and is designed to expand significantly, filling difficult-to-reach corners and crevices.  

The advantage of spray foam is its ability to provide high R-value insulation without the inconvenience of handling large foam sheets. Liquid-stored foam allows for easy application and smooth, even coverage. Whether you are an individual property owner or a commercial contractor, spray foam insulation offers the benefit of quick application and high efficiency as a thermal insulator. 


Create a Moisture Vapour Barrier with SPF 

The polyurethane foam we use not only enhances thermal efficiency by keeping buildings warmer in winter and cooler in summer but also acts as a moisture-resistant barrier. Compared to fibreglass, the initial cost of installing foam insulation is offset by the energy savings it provides over time. Especially in humid environments, foam insulation works year-round to prevent water particles from entering your home, thereby protecting both the insulation and other building materials from moisture damage.
