In an effort to try and keep the vermin and snakes out of our shed we decided to try a bulk buy spray foam system.
We are pretty happy with the way it turned out and 4 months on it's still great.

What is the purpose of foam in wall?
Spray foam is a type of insulation that expands after you spray. The foam expands and seals, deterring moisture (which can create mold) and pests from eating through your walls. It protects the lining of your house, and can even assist in the heating and cooling of your house during those unbearably cold or hot days.
