Spray Foam Insulation Kits FAQs
How to Buy FAQs
Both the Large and Small kits come with 10 nozzles and 3 fan spray tips. You also get 3 more nozzles and 10 fan spray tips with Free Supersizing for a total of 13 each. This time 13 is your lucky number because this is usually plenty of nozzles and few people need to purchase more.
Every time you stop spraying for 30 seconds or more, you must change the nozzle. This keeps the foam from clogging the gun. If the gun becomes clogged, you’ll need to purchase a new one.
How to Use FAQs
It depends on your project.
Floor of attic: Just one inch will seal the air flow from the living space to the attic. Follow with fiberglass or cellulose to build up the R-value.
Rim Joists: 2 to 3 inches. If you are sealing them in to make a finished basement, follow the guidelines below.
Walls: 2 to 3 inches.
Metal Buildings: 1 inch stops condensation.
The layer of foam helps the other insulations perform better by providing the tight air seal. If you want to do all spray foam insulation, you’ll be glad you did, because every additional inch maximizes the R-value for that space, requiring less and less energy to heat or cool your home.
65-85 degrees Fahrenheit, 75 degrees is the ideal temperature for the surface you plan to spray.
The tanks also need to be between 65-85 degrees Fahrenheit for maximum performance. There is a temperature gauge on the B-tank that will show you when the tanks are in range.
Do you use the area for living space? If yes, do the rafters. If no, do the floor joists.
This is a very common challenge that many people face. Many of our homes and buildings have no insulation at all. While this kept costs low for the builders, it means you now pay huge energy bills to make up for it.
When filling existing walls or ceilings, use Foam it Green Slow Rise Formula. Check out our video on how to maximize your results and minimize the risks.
Product Info FAQs
Closed cell foam has significant advantages. Closed cell spray foam has approximately double the R-value in 1 inch of open celled foams. Closed Cell resists water and seals out air in just 1 inch. Just sealing out air leaks alone can lead to a dramatic savings in energy costs according to the U.S. Department of Energy.
Open cell foams hold water which can quickly lead to mold problems. Therefore, only use open cell in internal walls.
There are NO spray polyurethane foam brands that are “soy-based” or “bio-based”. It is illegal to claim as such.
Foam it Green spray foam kits are classified as green because:
- Our spray foam stops tremendous amounts of energy waste by sealing out air leaks.
- Foam it Green has a very high r-value (7) in just 1 inch.
- Foam it Green minimizes transportation impact because it is 100% American Made.
Foam It Green® is not fire proof, but it is Class I fire retardant insulation.
“Class 1” foam means that the foam has been tested by Underwriter’s Laboratories (UL) for flame spread and smoke development, according to the ASTM E-84 tunnel test for surface burning characteristics.
Trouble Shooting FAQs
To caulk large gaps, simply run a bead of foam into the cavity.
Place the tip of the nozzle at the edge of the cavity and slowly pull the trigger. Remember that the foam will expand five or six times its original volume. If the foam cures, and you have not filled the cavity to your satisfaction, you can always add more foam. One layer will bond to the other. If you dispense too much foam, you can trim away the excess with a sharp knife.
Foam it Green makes that easy – if it’s light green and dry to the touch in 2 minutes, it’s good. Like any two component polyurethane foam, Foam it Green is dependent upon the gun dispensing both chemicals in a one-to-one ratio. If it’s not green and dry to the touch in 2 minutes, do the following:
Remove the nozzle from the gun and point the gun into a waste container. Pull the trigger and observe the chemical streams. You should see two chemical streams flowing at equal velocity.
The A component is yellow in color and the B component is blue in color.
Please check below to see what you should do:
- Two chemical streams flowing at equal velocity
– You are all set to start your project.
- There’s more “A” chemical flowing than “B” chemical, your foam is probably darker in color and may have a crunchy, glassy surface.
- First check the temperature strip – is the indicator in the blue area?
- Cold chemicals will result in foam that is “A” component rich. If the temperature strip indicator is in the blue section, warm the tanks, shake them vigorously, and check the chemical flow again.
- If the temperature strip indicates the mid-green section, meaning the temperature is right for dispensing, then check the “B” component tank. Be sure it is not empty. Be sure the valve is turned all the way on.
- If all of these things seem to be right, contact us for further action.
- There’s more “B” component than “A” component, your foam is probably bluer in color with a spongy surface texture
- First check the temperature sensing strip – is it indicating in the red section?
- Chemicals that are too warm often result in foam that is “B” component rich. Cool the tanks, then shake them vigorously, and check the chemical flow again.
- If the temperature seems right, check the “A” component tank. Be sure that it is not empty. Be sure the valve is turned all the way on.
- If all of these things seem to be right, contact us for further action.
- If the foam seems to be rising but is blue, and reverts back to a liquid after a couple of minutes, this means you’re not spraying out any A component.
We strongly recommend that the gun is dispensed a minimum of once every week, more often in humid climates. Failure to do so will result in a blockage on the “A” component side of the gun. The A component is essentially super glue – and can clog the sprayer if not maintained. If there is no chemical flow, the gun/hose assembly will need to be changed.
- Neither component is flowing well
If you do not seem to be getting acceptable flow from both components, this would indicate a lack of pressure.
The only known cause for both tanks to lose pressure is if the kit was used while lying on its side.
The chemical tanks are similar to aerosol cans. If you dispense foam while they are on their side, the propellant escapes through the hose and the pressure is lost. There is no remedy for this. You can only prevent this from happening by keeping the systems in their upright position during use.
The best way to avoid messes is to cover anything you don’t want foam on.
Cleanup of “B” component can be accomplished using soap and water. Make sure you get it while it is still in the liquid state.
Cleanup of “A” component is like cleaning up super glue. Do not use water to clean up the “A” component chemical. Be sure to wear nitril or butyl rubber gloves and proper respiratory equipment. For a small amount of chemical, saturate a rag with dish soap and wipe it up. Be sure to do this while the chemical is still liquid. Be aware that there may likely be a stain. For larger amounts of chemical, refer to the safety data sheet.
If you store it at high temperatures, it reduces the shelf life. Pressurized containers may rupture if stored above 120°F.
If you store it at lower temperatures, the liquid components may separate.
Always store foam upright to prevent loss of foam pressure.
Lower temperatures will cause slower flow rates and a longer cure time. The mixing and spray pattern will be adversely affected. It will be darker in color and may have a crunchy, glassy surface texture. Warm the tanks, shake them vigorously, and check the chemical flow from the face of the gun.
Higher temperatures will cause faster flow rates, created by a higher pressure in the can. The yield and density of the foam may be affected in extreme conditions. Cool the tanks, shake them vigorously and check the chemical flow from the face of the gun.
Surfaces that are colder will result in reduced yield. This is caused by the cold surface extracting the heat from the exothermic reaction resulting in a reduced rise, thus a reduced yield.
Cold surfaces can also affect adhesion because the cold robs the heat from the chemical reaction. Using test patches, patience, and even a thermal scanner (around $50) can help your cold weather foaming go smoothly. By making sure that the foam really bonds to the surface, you create a seamless air barrier that protects your home for years to come.
If the surface is cold, there may also be condensation, which would be like spraying foam onto a wet surface. Therefore, the foam may not adhere to the surface. The only way to determine if this will happen is to do a test patch. If the foam sticks to the cold surface, spray the least thickness possible to simply raise the surface temperature to a level that would be closer to ideal temperatures. Allow that layer to cure. Then add the desired thickness to achieve your R-value.
If the surface is too cold you will hear a popping noise as the foam shrinks back.
Surfaces that are too warm may result in the foam curing too fast. This would also result in a reduced yield because the foam would not have enough time to reach the full rise before a tack free state. In addition, extreme cases may result in loss of adhesion because the foam would cure so fast it could not develop a bond to the surface before it hardened.
Wear goggles to protect your eyes. If foam gets in the eyes, flush eyes with water for 15 minutes and immediately consult a physician.
Wear rubber gloves to protect your skin. Use a coverall to protect your clothes. If you do get it on your skin, scrub repeatedly with soap (abrasive cleaner or pumice soap works best) and water. Apply hand cream if irritation develops, and consult a physician if it persists.
