What is SPF?
SPF stands for Spray Polyurethane Foam. Spray foam insulation is comprised of a two part liquid that when combined expands and hardens filling every nook and cranny that it comes in contact with.
What is Open Cell Spray Foam?
Open Cell Spray Foam is a low density spray polyurethane foam and is sometimes referred to as half pound foam as it usually comes in ½ pound per cubic foot. Open Cell starts as a two part liquid and expands 120 times its original size when the gun mixes and sprays the two parts together. It makes for a great Air Barrier & Sound Barrier when applied at 3 ½ inches thick or higher depending on manufacturer.
What is Closed Cell Spray Foam?
Closed Cell Spray Foam is a medium density spray polyurethane foam and is sometimes referred to as two pound foam as it usually comes in 2 pound per cubic foot. Closed Cell starts as a two part liquid and expands 30-40 times its original size when the gun mixes and sprays the two parts together. The following information depends on the manufacturer. Closed Cell Spray Foam makes for a great Air Barrier at 1 inch thick or higher. At 1 5/8 inches thick or higher it is a Class II Vapor Retarder. At 1 inch thick or higher it adds amazing structural strength.
What is the Difference Between Open Cell & Closed Cell Spray Foam?
The simple answer is that they are two different types of spray foam and each have different attributes. Open Cell Spray Foam typically has an R-Value of 3.5 to 3.7 per inch, is an Air Barrier and has good sound absorption. Closed Cell Spray Foam typically has an R-Value of 6 to 7 per inch, is an Air Barrier, Vapor Retarder & adds structural strength. While Closed Cell Spray Foam looks like the obvious choice, it is usually about 3 times more expensive per inch than Open Cell Spray Foam. We have a blog that explains all of this in more detail.
Should I Choose Open Cell or Closed Cell Spray Foam?
The answer is yes! That is to say you could choose one or the other or a mixture of the two. The answer will always vary based upon each unique scenario as well as budget. Closed cell could be used for almost every situation. It is superior in many ways but is not as popular of a choice due to its price point. If you are on a budget, open cell would be more cost effective, however if you want the best, closed cell is the way to go.
What is Spray Foam Roofing?
Spray Foam Roofing is typically found more on commercial and industrial buildings rather than residential buildings, however it can be used on almost any hard surface in many types of applications. It is a much different product than you’re traditional roofing materials. The Spray Foam Roofing System is comprised of two parts: a higher density closed cell spray foam (3 or 4 lbs per cubic foot usually) along with a top coating such as acrylic or silicone to protect the foam from the UV rays of the sun.
What are Roof Coatings?
Roof coatings are the protective layer that goes over roof assemblies to protect them from the destructive effects of the weather and the surrounding environment. Some popular roof coatings are Acrylic, Silicone & Polyurea. Acrylic roof coatings are water based, extremely reflective and help with blocking the suns UV rays, however some drawbacks or in doesn’t usually do well in ponding water and can’t typically be applied in the winter. Silicone roof coatings are good in ponding water and tend to withstand the elements better and since they are cured with moisture, humidity is not a problem. Once Silicone is used, you are pretty much locked in to using silicone as it is hard to get anything to stick to silicone which makes maintaining it more difficult. Polyurea roof coatings are typically more expensive than other roof coatings. This mainly has to do with its many attributes. It sets up quickly and is not really affected by extreme changes in weather.
How Much Does Spray Foam Weigh?
The weight of the Spray Foam will depend on the materials being used. For example if using a half pound foam for open cell, it is going to be a half pound per cubic foot (12”x12”x12”). This would equate to .146 pounds per square foot if insulating your walls at 3.5 inches thick. Two pound closed cell spray foam would be two pounds per cubic foot. So for example if spraying two inches of closed cell, you would have 1/3 of a pound per square foot. Roofing Spray foam comes in several high density options usually between 3 to 4 pounds per cubic foot depending on application. The formula to figuring out how much the spray foam weighs is to take the poundage of the spray foam, so for the last example let’s take 3 pound roof spray foam. Then you find out how deep the spray foam was sprayed, so in this example let’s say two inches. Then we divide the number of inches sprayed (2 inches) by how many inches deep a cubic foot is (12 inches). So 2 ÷ 12 = .167 then we multiply that by the density of the foam per cubic foot (3 pounds). So .167 x 3= .5 pounds or half a pound.
What is R-Value?
R-Value is a unit of measurement of an insulation material. It measures how well the insulation (or any object really) prevents the transfer of heat. Open cell spray foam typically has an R-Value of 3.5 to 3.7 per inch and closed cell spray foam typically has an R-Value of 6 to 7 per inch.
What is a Thermal Barrier?
A thermal barrier is a material that goes between foam plastics such as spray polyurethane foam and an interior space that is made to slow the rising heat of the foam if there was a fire. In order for a product to be an official thermal barrier, it has to pass a rigorous 15 minute burn test in accordance with NFPA 286. The 3 main thermal barriers that qualify is ½” Gypsum Board also known as Drywall or Sheetrock, 19/32” OSB or Plywood or an approved intumescent coating such as DC315.
What is a Ignition Barrier?
An ignition barrier is an exception allowed in place of a thermal barrier only in attics and crawl spaces where entry is restricted to maintenance and repairs through a hatch. For example if the attic or crawl space is easily accessible and/or items will be stored there, then a thermal barrier would be required instead. Examples of an ignition barrier are 1 ½” mineral fiber insulation, ¼” wood structural panels, 3/8” particleboard, 1/4” hardboard, 3/8” gypsum wallboard, 16 mil corrosion resistant steel and an approved intumescent coating such as DC315.
What is the Difference Between a Board Foot and a Square Foot?
A board foot is measured at (12”x12”x1”) whereas a square foot is simply measured at (12”x12”). In the spray foam industry where you can apply product at different thicknesses, it is necessary to measure in board feet as a proposal is based upon each inch of product thickness that will be used. Imagine someone had a warehouse that had 20,000 square feet of wall and roof decking that needed spray foam. There is a big difference in how much product would be required for that warehouse as well as how much would be quoted between one, two or three inches thick of closed cell spray foam.
What is a Building Envelope?
A building envelope is essentially drawing a line between everything that is on the inside of your homes’ insulation and outside of your homes’ insulation. This is also known as the dividing line between the conditioned and unconditioned part of your home.
What is the Difference Between a Conditioned and an Unconditioned Space?
The conditioned space is everything within your house that is on the inside of your homes’ insulation. The unconditioned space is everything that is on the outside of your homes’ insulation.
Does SPF Emit Odor?
Some of the components of the Spray Foam can have an odor for a few days after the installation took place. If the SPF was applied in an area that is not well ventilated, additional ventilation of the installed area is recommended. After ventilated for a couple days, if an odor persists please contact us so we can come take a look.
Do You Offer a Warranty?
Our wall & attic Spray Foam comes with a limited lifetime warranty from the manufacturer. If a commercial property qualifies for our Hail Proof Roof, then it will come with a 20 year leak free warranty.
How Much Does SPF Cost?
Costs can vary based upon many factors such as how many board feet your project is, if you go with closed cell or open cell, how many inches of foam you want, if a thermal barrier is required (it is in most cases), what kind of space is being spray foamed (attic, crawl space, barn), the amount of prep work that is required, etc.
