Top Myths About Spray Foam Insulation

May 04, 2021

When done properly, home insulation can reduce energy costs by as much as fifty percent. Still, the effectiveness of your home insulation system will also depend on whether you chose the right kind of insulation for your needs.


There are various types of insulation, and each one can be extremely effective at increasing energy efficiency and decreasing outside noise. Some insulation systems even repel moisture, protecting wood in the home from mold, mildew, and rot. 


Foam Comfort, Inc, has been in the business of providing
spray foam insulation in Toronto since 2006. There are a lot of benefits to using spray foam insulation in the right situations. Still, some of our clients started out with a lot of concerns about the safety and efficacy of spray foam insulation, thanks to some notorious myths surrounding this kind of insulation. 


In this article, we will debunk some of these myths so you can rest assured about the safety and effectiveness of this specific type of home insulation. 

Myth #1: It’s New.


The spray foam insulation that we know today was developed by the United States military in the 1940s for use on military planes. Thirty years later, spray foam made the jump from airplanes to buildings. For fifty years now, homes and businesses have been using spray foam to create air barriers and sound barriers, so it is definitely not a new practice.

Myth #2: It Is Dangerous for Your Health and the Environment.


We at Foam Comfort only use materials that are EcoLogo-certified to be environmentally sound for their entire life cycle. EcoLogo began as a Canadian Government certification measure, but it is now accepted worldwide. The materials that we use do not emit chemicals that contribute to climate change. 


Closed-cell spray foam insulation repels moisture, protecting the air that you breathe from dangerous mold spores. The materials we use are also approved by Health Canada for schools and hospitals. Used as home insulation materials, our products increase the energy efficiency of the home, making them beneficial for the planet over time. 

Myth #3: It Makes Your Home Too ‘Air-Tight.’


While spray insulation is very effective in creating air-tight barriers, ventilation systems still allow air to move freely around the home. Our products expand and create these air-tight barriers exactly where you want them. In any case, plenty of air moves around the home and vents to the outside through all the normal attic vents, doors, and windows. 


Air ventilation is an important part of energy efficiency in a residential setting, as well. As temperatures rise in the attic, the heat vents upwards and out, while insulation provides an extra barrier for the home’s ceilings. Spray foam enhances this feature by plugging unwanted air leaks while leaving the vents free to expel the hot or cold air outside of the building.

Myth #4: Nominal R-Value Is More Important Than Effective R-Value.


R-value measures how well insulation resists heat. It is determined by testing insulation in tepid 70-degree conditions. Depending on how the insulation holds up in those conditions, an R-value is assigned. Regardless of thickness, insulation with an R-value of 20 will provide the same level of heat protection.


In real life, however, insulation has to do its job in temperatures way higher or lower than 70 degrees. As such, the “effective” R-value may be much different from the assigned, nominal R-value. If insulation is not applied to create air-tight seals, air pockets can form and reduce the effective R-value. For this reason, having professionals install the foam can save you major headaches down the road.

For this 1930’s-built house, a re-roof allowed our crew of trained professionals to spray down into the roof joists from above. The Foam Comfort Crew, along with the careful coordination of a highly skilled roofing crew, allowed the two trades to work seamlessly to prepare the area for insulation, install a 2lb spray foam solution and then to close, seal and shingle the roof. All old homes built in this area had minimal to no insulation in the roofline and attic areas often involved knee walls and dormers, further adding to the complexity. Once the old roof was removed, a cardboard baffle was secured in the joist cavity and then a 2lb medium density spray foam was applied. The 2lb foam is a vapor barrier and will not allow any condensation to form in the roof cavity below as it provides a monolithic barrier. Removing lathe and plaster from the interior is a major and totally disruptive endeavor, so using an exterior method to insulate, such as what was done in this scenario, can significantly reduce the mess and inconvenience to the inhabitants.

Insulating a camper van is essential for creating a comfortable and livable space. It helps regulate temperature, reduce noise, and prevent condensation. Closed-cell spray foam insulation is the most popular insulation option for camper van builds. It provides a high R-value (a measure of insulation effectiveness) and seals all gaps and cracks. Closed-cell spray foam insulation is also waterproof and prevents condensation.
