Spray foam is a type of insulation specifically created to prevent the movement of the heat between the exterior and interior of a house. It’s an excellent insulation material, thanks to its sturdy covering block.
Besides heat, this material is also excellent at blocking noise, while some of its distinct types are designed to stop the condensation of water vapor. Apart from having numerous types, the spray foam insulation cost per square foot also varies.
Spray Foam Insulation Cost Per Square Foot
Thanks to the advancement of technology, spray foam has been the best insulation available in the market. Insulating a house with this material will help you save electricity bills nearly up to 50%. So, if you are wondering, is spray foam insulation worth it? You already know the answer.
If you are interested in using spray foam to insulate your house, you need to know how much the budget you should prepare. The average cost of spray foam insulation per square foot is around $0.44 to $1.50. However, spray foam is available in two different types, that is closed-cell and open-cell.
1. Open-cell
The main difference between closed- and open-cell insulation is that the latter has higher versatility and tends to be more ‘soft’. If you would like to install this spray foam type, you will need to prepare $0.35 to $0.55 per square foot.
2. Closed-cell
Closed-cell spray foam will cost around $1.00 to $2.00 per square foot. However, if the square footage is larger, the cost per square will be automatically lower. For instance, to cover an area of 1,500 square feet with closed-cell insulation, you will spend around $1,500 to $2,250.
The budget you will need to prepare is slightly different if you want to insulate a metal building. To cover a metal area of 1,500 square feet, you will spend around $1,600 to $2,400.
That’s only the initial price of the material. Remember that the area you would like to be insulated also affects the cost of spray foam. So, how much does spray foam insulation cost per square foot based on the areas?
Here is the breakdown:
- Basement Spray Foam Insulation Cost
Walls in a cellar normally need larger foam with water resistance ability since space is beneath the ground and is prone to moisture. To insulate this area, you will need about $2,140.
- Attic Spray Foam Insulation Cost
Batts and foam rolls are the two forms of insulations that are usually used to insulate attics. Even so, you can still complement it with spray foam. You may expect to spend about $2,200 to insulate a standard-sized attic.
- Roof Spray Foam Insulation Cost
The vast majority of insulation is installed on the roof due to the rising heat. Apart from covering the attic, you can also add additional protection by insulating the roof. This form of insulation is usually installed between the beams. In general, the spray foam insulation cost per square foot for a roofing system is around $1,650 to $2,200.
