Once residential property owners learn about the many benefits of spray foam insulation, from improving energy efficiency to making their home more clean, safe, and comfortable, their next question is almost always, “So how much does it cost?”
The Cost of Spray Foam Insulation
There are multiple factors that go into the overall cost of upgrading your home’s attic to spray foam, but here’s a broad overview to help you plan for this wise investment in your property.
Small attics: If your home’s attic is 4 feet or lower at the peak, it’s most likely too small of an area for spray foam insulation. This area would be best suited for fiberglass insulation.
Medium-sized attics: (4 Bedroom, 3 Bath) $6500
Large attics: $9,000 and up

Comparing the Cost of Spray Foam vs. Fiberglass Insulation
It’s a common myth that spray foam insulation is substantially more expensive than fiberglass, (blown-in insulation). However, the price per square foot is oftentimes about the same.*
While spray foam can sometimes be a larger investment up front, it doesn’t require frequent updating and ongoing maintenance. You can “set it and forget it,” confidently knowing it’s made to last throughout the lifespan of your structure, or approximately 80-100 years. This is not the case for fiberglass insulation, which needs to be replaced or replenished every 5-10 years due to wind washing, settling, or damage done by people or pests walking on it!
There are also special rebates available through power companies like Georgia Power, as well as a federal tax credit of as much as $1200.00 available to those who upgrade their home with spray foam insulation, bringing the overall investment down even further.
In addition, spray foam can save you money on your energy bills year-round. In fact, according to a recent Department of Energy study, homeowners who installed spray foam insulation saved an average of 20% on their heating and cooling costs.
*Most companies have a minimum of $2500 for spray foam projects, and $1,000 for fiberglass projects, due to the equipment and crews it takes to set up for each type of project.
The Cost of Insulating a Metal Building
f you’re looking for a durable and energy-efficient insulation for your metal building, spray foam is a wise solution! Closed-cell spray foam insulation is popular for metal buildings because it provides superior thermal performance, air sealing, and moisture management. It also helps to reduce noise pollution, prevent pest infiltration, and reduce the chance of mold and mildew growth.
The cost of spray foam insulation varies depending on the size of the building, the type of insulation, and the thickness of the application. Here’s a price range guide to help you as you plan to insulate your metal building structure with spray foam.
20×20 building: $4,120
