Spray Polyurethane Foam


New Orleans Open Cell Insulation - Star Spray FoamSpray Polyurethane Foam (SPF) is a chemical that is known to be great in insulation and reducing air leakage. SPF is a very easy material that fills walls and ceiling cavities completely. There are two components called “A” and “B”. They are mixed before application and applied through heated hoses. This mixture of A and B components expands and hardens.

Star Spray New Orleans has Open Cell foam and Closed Cell foam insulation available and each has different characteristics for different purposes.


Open Cell Insulation: Balancing Humidity


Breathability that’s great for humid areas

Open cell foam is composed of less material with lower R-value per inch compared to closed cell foam. It is also naturally cheaper but has basically the same thickness as the closed cell.

Open cell foam blowing agent for installation is water. When it reacts with air, it becomes Carbon dioxide which then expands right away. It’s called “Open cell” because the bubbles burst before the plastic sets. The result is a foam that is has a spongy texture but has light density. It’s also called “half-pound” for weighing only half a pound per cubic foot.

The density yields an R-value of about 3.6 for every inch. This low density makes it permeable. It’s great for attics in general.
Open cell foam is known for its vapor breathability. It’s a good choice in hot and humid climates.

Great for soundproofing


Open cell foam can offer twice the normal noise reduction coefficient as compared to the closed cell foam. Since the water dissipates right away, the R-value does not degenerate. Open cell foam is an effective air barrier. It absorbs and holds water.

Some advantages would include:

  • Lower raw material or resource use
  • Allows for bi-directional drying
  • Great in accommodating long-term seasonal movement
  • Hydrophobic
  • Good as air barrier
  • Good for insulation and aged heat resistance
  • Enhances sound proofing
  • Permeable for humid climates


Strength and Resistance Closed Cell Insulation

Higher R-value for greater strength and tenacity


Closed cell insulation is more expensive than the open cell. The reason for this much more costly picture is that it provides a higher R-value per inch compared to open cell and even fiberglass or cellulose. You can also check out our quality cellulose insulation service in New Orleans.

The closed cell spray foam cost is in fact the most expensive type of residential or commercial insulation that you can get. It’s the best but you have to factor in how it is installed. A bad installation will not yield that expected result. It is important that only professionals will handle it.

If the open cell is called “half-pound”, the closed cell is called “two-pound”. It is known to be a vapor retarder and 2 1/2 inches of it has a permanence of 0.8 perm.

They say that it has high global-warming potential due to the hydrofluorocarbon (HFC) composition. It is said to be 1,400 times more potent than the carbon dioxide in open cell foam insulation. Usually, contractors just use a thin layer of this foam.

High heat resistance


It’s ideal for cold climates unlike open cell which is perfect for humid climates. It is thicker and less permeable so it’s not as breathable but it is instead more compact instead.The right amount of heat or temperature must be distributed inside a building and closed-cell insulation has the capabilities to make this happen. It has great density and a tenacity similar to that of a glue’s. It is so strong that it is best used to add structural strength to walls, ceilings, and roofs.


Can resist water degradation and moisture better


It’s not just great with insulating heat but it can also hold off water and moisture ideal for metal buildings. Excess moisture can destroy an insulated surface since there is lack of generated heat inside a structure. With closed cell insulation, water degradation is controlled and a fair amount of heat and moisture are distributed.

Some advantages would include:

  • Application in very low temperatures
  • Great for racking strength
  • Great for impact resistance
  • Ideal for continuous insulation solutions
  • Can accommodate narrow spaces because of higher R-value
  • Lower vapor and this less permeability
  • Ideal for flood-prone areas
  • High tenacity and bond strength
