Spray 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 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.
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.
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. Closed cell spray foam 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.
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.
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 close-cell insulation, water degradation is controlled and a fair amount of heat and moisture are distributed.
Star Spray Foam New Orleans is a company that contains a team of experts in both open cell and closed cell installation. Each of the technicians has the knowledge, skills, and experience to properly install your insulation systems. Before anything else, there is a diagnosis and we will be presenting you a report and a work plan of what we suggest is best for your home or office. Each type of insulation has its own pro’s and con’s and there are certain situations where one is better than the other. We want to provide you with quality workmanship and therefore, we want to install what is most suited to your home or office while factoring in the unique circumstances of your home or building. The climate, structure, purpose, and other relevant and important considerations will be taken into account.
While others may say that they can just look up the internet DIYs, we highly suggest that you call us instead. Your insulation system should not be taken lightly and you cannot take chances for it to go awry. We hope to hear from you soon! Let’s talk about how we can improve your space.
