Question 1

What is spray foam insulation?

Accepted Answer

Spray foam insulation, also referred to as spray polyurethane foam insulation, is a product applied using a sprayer that combines two liquid components. Upon application, the foam expands to fill gaps and cover surfaces entirely. It's suitable for insulating walls, attics, ceilings, floors, basements, and crawlspaces. The two liquid components typically contain methylene diphenyl diisocyanate (MDI), polymeric methylene diphenyl diisocyanate (pMDI), polyols, catalysts, blowing agents, flame retardants, and surfactants.

Question 2

How is spray foam different from traditional insulation?

Accepted Answer

The primary distinction between spray foam insulation and conventional insulation materials like fiberglass or cellulose is that spray foam functions as both an air barrier and thermal barrier in one product. Traditional insulation forms do not impede air flow. Spray foam insulation effectively provides insulation and air sealing simultaneously, which is crucial for establishing a continuous and complete thermal and air barrier within the building envelope.

Question 3

What is the difference between "closed" cell and "open" cell spray foam?

Accepted Answer

* Spray foam insulation comes in two distinct types: closed cell and open cell. Closed cell foam hardens into a rigid state, while open cell foam cures with a softer, spongy texture. In terms of insulation value, closed cell foam provides approximately R-7 per inch, whereas open cell offers around R-4 per inch. Closed cell foam creates an air barrier at just 1 inch of application, while open cell typically requires 3 inches. Additionally, open cell foam is water-permeable, unlike closed cell foam. Open cell foam also offers sound-dampening properties.

Question 4

What type of spray foam is best for my home, and what if I have a roof leak?

Accepted Answer

While each project has unique requirements, we generally suggest open cell spray foam for attic insulation and closed cell spray foam for basement or crawlspace applications. Open cell foam is preferable for attics due to its moisture permeability, allowing water from potential roof leaks to pass through and be detected. Closed cell foam is not recommended for attic use as it could trap moisture from leaks, potentially causing roof rot and damage. However, closed cell foam may be suitable along the roof-line in hurricane-prone or high-wind areas for added structural integrity. For basements and crawlspaces, closed cell foam is ideal as it creates a moisture barrier, preventing damp air from entering the living space.

Question 5

Should I have the attic floor or roof decking spray foamed?

Accepted Answer

Applying spray foam along the roof, rather than the attic floor, offers additional benefits. It transforms the attic into a climate-controlled storage space, making it more comfortable and freeing up floor space previously covered by traditional insulation. This approach has also been shown to extend the lifespan of HVAC air handlers located in attics by shielding them from temperature extremes. The decision between insulating the attic floor or roof decking may depend on budget considerations, as the attic floor typically has less square footage than the roofline or decking.

Question 6

How is spray foam different in existing homes versus new construction?

Accepted Answer

For new construction or major renovation projects, we can insulate exterior walls with spray foam or use a combination of spray foam and traditional fiberglass batts through a process called 'flash and batt.' In existing homes, focusing on insulating the attic and crawlspace or basement can significantly improve comfort and efficiency without the need to insulate walls. Wall insulation in existing homes can be invasive, so addressing the top and bottom of the thermal boundary of the conditioned space often suffices.

Question 7

Is spray foam insulation safe?

Accepted Answer

Spray foam insulation is indeed safe. However, some individuals may be sensitive to the fumes produced during the installation process, known as off-gassing. As a precaution, we advise occupants to vacate the premises once spraying begins and remain away for 12-24 hours after completion. This allows the foam to fully off-gas, ensuring the home is completely safe for habitation thereafter.

Question 8

How much does spray foam cost?

Accepted Answer

The cost of spray foam insulation is influenced by various factors. Generally, spray foam is approximately twice the cost of traditional fiberglass insulation. The final price depends on the job size, foam type, whether existing insulation needs removal, and local requirements for ignition barriers. Despite the higher cost, spray foam offers superior performance as it acts as both an air barrier and insulator, providing value for the investment when installed by our trained professionals.

Question 9

How long is the payback? / Will it save me money on my power bills?

Accepted Answer

Spray foam insulation does indeed reduce energy costs. The exact payback period varies depending on factors such as home occupancy patterns and HVAC system usage. Our clients typically report energy bill savings ranging from 15% to 30% in spray foam insulated homes compared to traditionally insulated homes with fiberglass insulation and inadequate air sealing.

Question 10

How long does spray foam last?

Accepted Answer

When protected from direct sunlight and left undisturbed, spray foam insulation can last for the entire lifespan of the structure. It does not degrade over time, making it a long-lasting insulation solution.

Question 11

What types of spray foam insulation does JGL Spray Foam Insulation offer?

Accepted Answer

They offer both closed cell and open cell spray foam insulation, each with different characteristics and uses.

Question 12

How is spray foam insulation different from traditional insulation materials?

Accepted Answer

Spray foam acts as both an air barrier and thermal barrier, unlike traditional insulation which typically does not block airflow.

Question 13

What spray foam type is recommended for attics and basements?

Accepted Answer

Open cell foam is commonly recommended for attic insulation due to moisture permeability, while closed cell foam is ideal for basements and crawlspaces as it prevents moisture infiltration.
