Hey everyone!! I just wanted to share my method for making lightweight haunt panels. Each panel is made of 4 2x3s and 1-2 foam insulation boards. The reason I use 1/2” foam insulation boards is 1. They are lightweight 2. They are strong and easy to pain 3. And they are rather inexpensive (1 4x8 panel for around 7$). Each of my wall panels are 6’ tall and 8’ wide. It is made of 1 1/2 sheets of foam board and some 2x3s. To attach the foam board to the frame I use construction adhesive and plastic capped roofing nails. Each board is super easy to make and they last for years. Here are some photos of the build.
