Top 7 Questions about Spray Foam Insulation

Top 7 Questions about Spray Foam Insulation

1. Which spray foam insulation do you need?

Every spray foam insulation manufacturer adds new features or improve an existing one. The one that you will need depends on your requirement. But without tallying the features, there are two different types of spray foam insulation. These are open-cell spray foam insulations and closed cell spray foam insulations.

Even though the raw ingredients of both the variants are kindred, the thickness differs among the options. 

Closed-cell foam has a denser formulation than Open cell foam insulation. The thickness of the spray foam insulation affects it in many positive aspects. But they cost more. 

2. Why should I choose spray foam insulation?

Open-cell foam insulation looks like cellulose or fiberglass. When fitted precisely, it provides complete insulation. The air-seal structure helps to capture the temperature for up to 40%, making spray foam insulation a great energy-saving option. 

On the other hand, closed-cell spray foam insulation is the next level insulator. It is the last card that’s up your sleeve to insulate your house. From air to vapor, it doesn’t allow anything to go through. Its dense structure provides complete insulation. It has an intrinsic structure along with the highest R-Value. 

R-Value indicates the insulation quality of your house. It is the value that you need to look for in your spray foam insulation to verify its heat loss resisting capability. So, the higher the R-value gets, the better will be the insulation. On average, closed-cell spray foam insulation has 7 R-value per inch. 

3. Is it possible to install the spray foam insulation in a crawl space with vents?

Yes, it is possible. Spray foam insulation can condition your attic remarkably. But, you will need the closed-cell spray foam as they are damp resistant as well. Open-cell foam insulation is prone to dampness which eventually makes it an ideal breeding ground for rodents and pests. 

Moreover, the open-cell foam cannot reach all the corners of your room, especially the cavities, because of the structure. Spray foam, on the other hand, can fill up all the joist’s pockets and voids. With the closed-cell spray foam insulation, you can access all the inaccessible corners. 

4. Can the spray foam insulation be installed directly to masonry?

Unlike open-cell foams, closed-cell spray foam insulation can quickly dry after application so they can be used directly to the masonry. 

Before applying the closed cell spray foam insulation, you may or may not use a primer. But if your wall is holding too much moisture, you may need to use a primer to avoid the moisture getting stuck between the wall and the spray foam insulation. It can rapidly degrade the wall. 

5. Is the spray foam insulation an inflammable material? 

Yes, it is flammable. As it happens, any foam plastic materials, be it foam boards, soundproofing foams, Styrofoam, extruded polystyrene, or spray foam, all of them are flammable. 

The flammability of the material fluctuates depending on the manufacturer and type. When exposed to a flammable heat source, spray foam insulation can combust. 

You can check whether your spray foam insulation is flammable by looking at the product’s documentation. And no matter what “the experts” might say, no spray foam insulation is completely incombustible. 

But a good quality spray foam insulation can be fire retardant. Which means they can reduce the time taken to burn and spread the fire. The type of preservative used is responsible for reducing the rate of fire spreading.  

6. Is the spray foam insulation waterproof?

No, they are not waterproof, but some of them are water-resistant. It depends on the thickness of the spray foam insulation. A spray foam insulation that has an R rating of more than 7 is waterproof. The high density of the foam prevents seeping. On the other hand, the open cells absorb a tremendous amount of water. 

7. What if my spray foam insulation gets punctured?

It’s not possible to cut through a closed-cell spray foam insulation completely because of its thickness. Unless it’s done deliberately using a machine, the small punctures that occur naturally can be sealed using any type of roofing material such as silicone, or caulk.
