How to Apply Spray Foam Insulation
Insulation is one of the keys to energy efficiency. The best heating and cooling system in the world will be inefficient if your home isn't properly insulated. If you're having problems with insulation, you may be hesitant to call in a contractor due to cost concerns. Insulation batts or rolls can be difficult and time-consuming to apply, which will be reflected in the price.
Fortunately, spray foam insulation is inexpensive and easy to apply. You can even do it yourself. Here are some tips for installing spray foam in your house:
1. Ventilate the area.
When applying spray foam, you'll want to make sure the area is well ventilated. Spray foam insulation will give off fumes while it's still wet. These fumes can lead to breathing difficulties or lightheadedness if inhaled. It's a good idea to wear a respirator while you work. Open windows in the area if that's an option. If you are applying spray foam insulation in a closed room such as an attic, use a fan to help ventilate the area.
2. Make sure the area is dry.
Spray foam insulation works by adhering to surfaces. In order for a bond to form, the surface needs to be completely dry. Ensure your attic or basement walls are not damp before you apply spray foam. Most people don't expect to find water in these spaces, but moisture can leak in during times of heavy rain and high humidity. It's a good idea to apply your spray foam insulation in the summer if you suspect you might have leaks.
3. Practice before you start.
If you've never applied spray foam before, you should practice first to get a feel for the material. Load your spray foam applicator and practice squeezing the trigger. Get a feel for how quickly the spray foam emerges from the nozzle and practice applying an even coat that is neither too thick nor too thin.
4. Plan to work for a while.
Spray foam dries quickly, which is one of the reasons people choose it for fast installations. Due to this quick-drying property, spray foam can dry inside your spray foam installer nozzle. You'll need to replace the nozzle after every installation session. If you have a limited number of nozzles available, you should plan to spray as much foam as possible during each session. Frequent breaks are not an option when it comes to efficient spray foam installation.
