Expanding foam insulation is made from polyurethane and, although it is more costly than other types of insulation, it is one of the most efficient. Unlike other insulation types, expanding foam insulation is fast to install and creates an airtight fill between the home and the outside wall. Follow the steps below for successful application.

Step 1 - Preparation

Working with expanding foam insulation is messy, so make sure you have a tarp on the floor and you're in your protective gear. Remove the drywall and any existing insulation.

Step 2 - Readying the Sprayer

Fill the sprayer expanding foam insulation or ready the insulation kit according to instructions. Twist the nozzle cap to the foam insulation can move freely from the reservoir to the nozzle.

Step 3 - Applying Expanding Foam Insulation

This can be a tricky process for a beginner, but once you get the hang of it, application will be easy. Make sure you are at least 18 inches from the area, but no more than 24 inches. Squeeze the trigger and apply the foam to the perimeter. Fill in the area with smooth back and forth movement.
