Take the Time to Get Your Site Prepared for a Safe Installation

When planning to apply spray foam insulation to a home, one of the most important stages to focus on is site preparation. If the site is properly prepared before you even begin your application, the process will go more smoothly and you'll reduce the risk of hazards and injuries. Here are a few factors to consider when preparing a home for spray foam safety.

  • Remember that the HVAC system should typically be shut down when working on the roof. This will prevent aerosols and vapors from the spray foam from flowing through the space. Plastic sheeting should be put in place after the HVAC system is turned off, and left in place for 24 hours after application is finished.
  • If the entire building is not vacated prior to the application, make sure you take measures to make sure vapors from the spray foam don't travel through the ventilation system to the occupied areas.
  • Designate a separate area for workers to take off and put on their protective gear. This way, you reduce the risk of exposure to the spray foam exhaust and encourage proper wearing of protective gear.
  • Identify adjacent surfaces that could possibly be damaged prior to beginning the application. Take measures to specifically protect those surfaces from overspray, such as applying plastic sheeting or windscreens.
  • Note the wind direction before you begin work, and use windscreens to protect from overspray. Note that the wind direction may change over a period of several days, and make sure you can move the windscreens to block wind from another direction if needed.

Spray foam safety starts not only with site preparation, but also with using the best materials. Visit the NCFI website to learn more about our spray foam materials, equipment, and applicator training programs.
