How much can I save by using spray foam?

Spray foam insulation is one of the most efficient types of insulation you can use to protect your home from heat or cold weather elements. Its characteristics act as an air barrier and insulation material in one, and its high R-value means that the roof decking can be applied to slow down the heat transfer in your house even when entering the attic. Spray foam allows you to use your small heating system, eliminating the need to ventilate the attic floor and causing fewer repairs to your HVAC system for the rest of your life. Protects invoices. If you need to know how much spray foam insulation will save on your electricity bills, there are many factors you should consider to calculate an estimate of the savings.

The Age of your House

The age of your home will affect how much savings you will receive by using spray foam insulation. The insulation code has changed a lot in the past 50 years, and newer homes with R30 insulation will have fewer savings after spraying foam with 3 to 4 inches of insulation compared to older homes built in the 1970s. Well-insulated houses will be somewhat protected from outside elements, and their energy bills will be lower because their basic level of insulation already helps.

How much will you save foam on the roof decoration?

New or well-insulated homes will see their heating and cooling costs decrease by 10% to 15%, while homes with much less insulation or combat fiberglass insulation will have a reduction of 20% to 30%.

How much foam will be saved in block walls?

In houses built before 1990, when spray foam is applied to the walls, the cost of this heating and air conditioning is reduced by 15% to 25% when exposed to more than two hours of sun.

One story vs. Two-story Homes

One-story homes will benefit more from spray foam than two-story homes. Existing houses with vaulted roofs and small attics cannot be upgraded to spray foam on the vault, as access is challenging. For purple roofs, an air barrier can be created between the purple roof and the accessible attic, creating an unconditional attic with a conditioned foam attic and no spray foam. 

When existing insulation is removed from the attic floor, homeowners save as much money as possible on their utility bills. Overall, insulation left on the attic floor with the foam sprayed on the roof terrace traps the heat inside the attic during the heat, increases the temperature even more in the absence of insulation on the attic floor.
