When Spray Foam Insulation is implemented appropriately in a building, it produces a complete air barrier while also delivering exceptional insulation or R-Value.

The advantage of having a more tightly sealed home is that all of the air you have to afford to heat to a pleasant level is no longer fleeing through the inescapable gaps and cracks in the conventional air barrier.

Spray foam insulation significantly reduces air movement, and because of its superior air sealing capabilities, it also prevents important air leakage from plumbing penetrations, ducts, plug sockets, basements, and many other draughty regions.

What is Return on Investment from spray foam insulation?

R-Value does not signify the very same stuff for spray foam insulation as it does for cellulose or fibreglass, which is why it is not as widely discussed.

Because spray foam forms an air seal, it prevents airflow from entering and leaving the home. So the airflow you spend to cleanse stays exactly where you want it, assisting you in maintaining a consistent temperature and a comfortable home.

R-Value is a measure of ...
... the thermal resistance of insulating material. The capacity to resist heat exchange or loss by conduction is referred to as thermal resistance. In general, heat is transferred to the colder surface when a hot or warm material comes into contact with a cold material.

This refers to the insulation's ability to withstand heat transmission through conduction. Spray foam works to block both conduction and circulation, or air movement, whereas fibreglass and cellulose only function to prevent conduction.

The ROI with Spray Foam Insulation

Spray insulation costs differ based on the product, supplier, and other factors. R-3.6 to R-3.9 per inch is open- spray foam insulation. R-6 to R-7 per inch is the R-value of closed cell spray foam insulation.

Because not all spray foams are created equal, you may be asking why per inch R-Value of open cell and closed cell spray foam differs.

The R-Value of spray foam is affected by several factors, including the kind of foam, the durability of the foam, and how effectively it resists moisture.

The R-Value of foam insulation is affected by how it is manufactured. Because the open cell is a lighter material, it has a lower R-Value, whereas the closed cell is thicker and denser, hence it has a higher R-Value. Because of its denser composition, heat takes longer to travel through closed-cell spray foam.

When you grab a typical metal skillet from your kitchen, it heats up quickly and cools down quickly due to the thinner metal. When we get out of the cast iron skillet in my kitchen, it takes longer to heat up because it is a thicker and denser material, similar to a closed cell.

Finally, the moisture absorption of the foam insulation is very important. If the spray foam is drenched in water and moisture is present in the pores, the water acts as a heat conductor and reduces the R-Value.
Because open cell spray foam is permeable to moisture, this occurs more frequently.

Because closed cell spray foam is moisture and water-resistant, water cannot pass through it, and so the R-Value remains unaffected.

Conclusion

When considering spray foam insulation to other materials such as fibreglass and cellulose, an air seal is a game changer in the real sense.
Circulation or air movement transports heat far faster than conduction. This is where the air seal plays a vital role.

Fibreglass and cellulose insulation both allow air to pass through them, however foam insulation does not.

This is why an air seal is almost as critical as conductive resistance, because what is the point of blocking heat transmission if you are not also preventing air circulation?

The dilemma is that neither fibreglass nor cellulose can prevent heat escape completely. R-Value alone only gauges heat transmission through conduction which is highly beneficial for fibrous materials.

The air seal developed by foam insulation prevents air from easily entering and escaping the house. It works to keep the temperature stable, allowing your air conditioning system and furnace to run less frequently.
