For those considering adding insulation to their existing home, their best option may be to use spray foam insulation. While other types of insulation may be cheaper alternatives, spray foam has the added benefit of being flexible enough to use on existing structures without the need for additional renovation. Spray foam can also effectively air seal rooms and walls.

This material has the highest R-value out of all the others. Since this material is sprayed on instead of packed or built, there is little to no gaps where air and heat can escape. Spray foam occupies less space than fiberglass or blown-in cellulose. Energy savings can also go up to 40% when using this type of insulation material.

Here are four areas of the home where spray foam insulation should be used to increase the house’s energy efficiency. From preventing moisture intrusion to keeping in heat, insulation can generate thousands of dollars of savings.

Insulating the Attic

The attic is one place where using spray foam as insulation can create the biggest impact. Before installing insulation, make sure to seal any air leaks and make necessary repairs. This will help improve the efficiency of the insulation. While loose-fill or batt insulation can also be used in the attic, gaps between batts can cause heat to be lost. Also, moisture commonly found in the attic can reduce the R-value of fiberglass once it has matted down the material.

If your attic can house a hot water tank, make sure there is an ignition barrier between the tank and the spray foam. This is to prevent any combustion from occurring, as the chemicals in spray foam can be flammable when exposed to high temperatures.

Insulating the Basement

From the very top to the very bottom of the home, the basement is another place where spray foam insulation can be at its peak efficiency. A correctly insulated basement can offer a cool dry living space. Basement wall insulation is always preferred to ceiling insulation because it is connected to other living spaces more than it is connected to the outside. Using spray foam insulation on the walls can provide insulation for both sides.

Insulating the exterior of the basement can minimize thermal bridging through the foundations, provide protection against moisture, and reduce condensation on surfaces within the basement. Spray foam insulation is recommended for finished basements as these are prone to moisture control issues such as humidity and mold.

Exterior Walls

Blow-in insulation, when installed with a dense pack technique, can provide significant air sealing. This is great for existing exterior walls, as it will not disturb the finished areas of the home. Consider using spray foam as well in this area as it is easy to manipulate without needing extra construction or renovation. If wall cavities are exposed, it is a great opportunity to install spray foam insulation. While batt insulation would be cheaper in these cases, it cannot provide an air seal like spray foam insulation can.

Floors Above Unheated Garages

For homes with unconditioned garages, it’s recommended to seal all sources of air leakage with the use of spray foam. Not only can this adequately insulate the space, it can also prevent contaminants from the garage from entering a conditioned space. Examples of such contaminants include car exhaust, paint solvents, and the like. Be sure to install an air barrier as well to minimize the effect of cold air on the insulation underneath the floor.

While DIY insulation using spray foam is not recommended, it is possible for those with significant know-how. This type of insulating material is best for areas of the home that are susceptible to moisture intrusion, as it has little to no gaps when installed. It is also recommended for finished areas where renovating or rebuilding insulation can be difficult or costly. It’s important to note that the use of spray foam would require proper protective gear, as gases released during installation should not be inhaled. In some geographical areas where the environment is mostly moisture you must have to use this type of spray foam insulation.

For homes that need a quick insulation upgrade, using spray foam can be a convenient and effective way to generate savings. While it may be more expensive than other materials, it does have the highest R-value of any available in the market. It also has the added benefit of flexibility and maneuverability.
