What is Off-Gassing?

spray foam insulation etobicokeOff-gassing refers to a process in which volatile organic compounds (VOCs) and harmful chemicals are released into the air. Many different household products, like paint and new furniture, require time to off-gas, and this is what happens after spray foam insulation is applied to the walls and surfaces of your home. The issue with off-gassing is that it results in harsh chemical smells throughout your home, and this can cause headaches, nausea, and vomiting, not to mention the fact that the VOCs being released can be toxic and harmful to your health. 

Does Spray Foam Insulation Off-Gas?

Since spray foam insulation is a product that goes from a liquid to a solid, it does off-gas during the drying process. The liquid compounds in the spray foam will evaporate into the air, releasing VOCs and effectively drying the insulation. Once your spray foam insulation is applied, it can take anywhere from one to three days for it to completely off-gas. While your insulation is off-gassing, it is crucial to ensure that your home has strong ventilation, as this will help remove the VOCs from the air and promote fresh airflow throughout the property. 

Is There a Reason to Worry?

Although off-gassing has the potential to release harmful chemicals into the air, you are not going to be residing in your home when this process is happening. When you get spray foam insulation in Etobicoke, your installation team will go through the rules with you for your health and safety. In addition to this, the off-gassing period is relatively short and only takes as long as the insulation is fully cured. Once this is done, off-gassing will stop. So there is no reason to worry about off-gassing, as it is a temporary process. If you notice any odd odours after installation, simply stay out of the house for another day and/or increase ventilation significantly to help eliminate the smell.
