When it comes to keeping your home comfortable, the right insulation is key. Not only will insulation help keep temperatures inside your home level, but it will also help you save on energy costs. There are various types of insulation to choose from. Spray foam has become popular in recent years for a variety of reasons. It's effective and can be installed in most homes. If you are thinking about adding spray foam insulation to your home, here are three things that you should know. 

Types of Spray Foam

The first thing that you should be aware of is that there are different types of spray foam insulation available. The option that works best for your home will depend on your local climate and what you are trying to accomplish with spray foam installation. The two main types of spray foam insulation are open-cell and closed-cell insulation. Open-cell spray foam is lighter and not as dense as closed-cell insulation. Due to these qualities, it is also typically less expensive but it doesn't insulate as well as closed-cell spray foam. Closed-cell spray foam is denser and less permeable and a great option if you are looking for a water vapor barrier.

The Cost of Spray Foam Insulation

If you are considering spray foam insulation services, the costs will vary depending on your spray foam insulation contractor, the type of spray foam used, the size of your home, and your insulation needs. The average cost of open-cell spray foam insulation is between $0.44 and $0.65 per board foot. Closed-cell spray foam insulation costs will typically range between $1 and $1.50 per board foot. Total costs typically average between $1,270 and $3,636 for the entire home.

Where to Use Spray Foam

If you are considering spray foam insulation, you will want to talk to your spray foam insulation contractor about where it makes sense to use this type of insulation. It may not be the right choice for your entire home. Spray foam works well for basement walls, roofing assemblies, and areas where installing traditional installation can be difficult. Spray foam can also work well for walls, ceilings, and even under slabs. However, it's easiest to install this type of insulation during the building process or during an extensive renovation.

If you are considering spray foam insulation, there are a few things that you should know. First, there's more than one type of spray foam insulation. Open-cell and closed-cell spray foams are available. Costs will vary but typically open-cell spray foam is the least expensive option. While this type of insulation can be very useful, it may not be right for your entire home. Your contractor will help you determine where the best locations are for this type of insulation.
