Insulation eliminates the need to constantly heat your home when it is cold or cool it when it is warm, so you get to save on the energy (and the money) you would have otherwise used. 

Among the different types of insulation, spray foam insulation is one of the most expensive. However, it comes with unique benefits that you cannot overlook. 

Here’s why you should choose spray foam insulation:
