Does foam insulation cause greenhouse gas emissions?



Is the insulation materials that we use to help save energy and combat climate change, also causing carbon emissions?
Materials for insulation used to save energy, also help in preventing climate change and cause greenhouse gas emissions.

Indeed they do and in more than one way. 
It is the first that it requires energy to make and transport these materials, which we call as "embodied energy"--and the use of fossil fuels to fulfill these energy requirements creates carbon dioxide (our major greenhouse gas). In a way, every insulation material has embodied Global Warming Potential (GWP). Two of the most commonly used insulation materials contain Hydrofluorocarbon (HFC) blowing agent which are extremely powerful greenhouse gases. The extruded polystyrene (XPS) is most well-known by the brand names Dow Styrofoam ("Bluebeard")"blueboard") Owens Corning Foamular ("pinkboard")"pinkboard") up to R-5 per inch. It is manufactured using HFC-134a that has a greenhouse gas GWP of 1,430 which means that it's 1430 times as powerful a greenhouse gas as carbon dioxide. (I must mention here that I'm still not 100% certain that XPS is made using HFC-134a, as manufacturers are hesitant to disclose the specific blowing agents they employ as they claim the information is confidential and that the safety data sheets haven't been updated to reflect the latest blowing agents that are mandatory on January 1st, 2010. However, a few hints in the technical documents have led me think it is this blowing agent employed.) Another insulation material produced using a blowing agent with high-GWP can be described as closed-cell spray polyurethane foam (SPF). The insulation material is sprayed into the building cavity or onto foundation wall, or onto roofs. It is then will insulate to around 6 R per square inch. A majority but not all closed-cell SPF is produced using HFC-245fa which has the 1.030 GWP. Certain closed-cell SPF is water-blown, eliminating this risk, even though the majority of them are HFC-blown. The open-cell (low-density) SPF like Icynene is completely water-blown and therefore has a low GWP. Lifetime GwP A blowing agent having A significant GWP is only a problem in the event that the chemical releases in time. Unfortunately there isn't much information about the speed at which this happens. Certain researchers, like L.D. Danny Harvey, Ph.D. of at the University of Toronto (who first expressed concern about their high-GWP foam insulation in a technical paper just a few years ago) is assuming that the portion of the blowing agents disintegrates in time, however, after speaking with experts from the industry, our research of Environmental Building News The company makes an alternative, more conservative approach that only about 50% leaks out over the duration of the insulation, which could be between 50 and 500 years.

When we mix the two sources (embodied the GWP, and the GWP that is related to the blowing agent that is used) in the case of an insulation product, we get what is known as the "lifetime the GWP" from these substances. For insulation materials that are made using HFC blowing agents, the bulk of the total GWP is out of the blowing agent. The table below outlines the assumptions we made within our EBN article. Payback of the lifetime GWP




If we can then determine how much energy a particular amount of insulation can save over the course of its lifespan (which is contingent on the location of the home situated and how efficient its heating and cooling system is) we can figure out how much "payback" from the life-time GWP of the insulation. This is the time required for the energy savings of the insulation to cover carbon dioxide emissions that result from the usage of this insulation. With the assistance by John Straube and Daniel Bergey from the Building Science Corporation in Westford, Massachusetts, we determined the paybacks when the use of different quantities of the insulation materials. This analysis is published in the June issue of Environmental Building News for those wanting to examine the results in greater depth. We examined the possibility of adding R-5 intervals of insulation in a two-by-six wall system that is insulated using dense-pack cellulose (whole-wall R-value 14 for the wall to be used as the starting point). The energy model assumes that the structure is located situated in a relatively cold Boston climate. This is illustrated in two graphs. The positive side is that, aside from XPS and HFC-blown SPF the payback time for the lifetime GWP for insulation materials is quite low. If you add 4 inches of polyisocyanurate (R-25) to the wall of 2x6, for instance, (R-39 total) the lifetime GWP payback for the additional polyiso insulation would take 2.7 years. If you get to an R-60 final value for the wall (adding 7.5 inches of polyiso) then the payback will be just a little over four years.

If it's XPS that you're adding to your two-by-six wall, the payback time for the insulation added is more extensive. One inch of XPS will pay back 36 years in. If you add two inches, the payback increases to 46 years and when you add four inches, it's 65 years. If you go to an R-value of R-60 (adding approximately nine inches worth of XPS) will yield an average payback of more than 110 years. For SPF the paybacks will be the same, although slightly lower. 

Bottom Line: Avoid XPS and SPF. What does all this mean? These variations are significant enough that even if the assumptions are incorrect by a significant amount and we are able to draw generalizations about the best choices. If we're building extremely insulated structures and are doing it in part in order to limit global warming, we must utilize insulation materials other than XPS or SPF at a minimum until the insulation materials are made using blowing agents with lower GWP. (Low-GWP blowing agents like hydro fluoro olefins (HFOs) are most likely to come from Honeywell as well as DuPont over the coming years, but it's not known how fast XPS, as well as SPF manufacturers, will switch to these compounds or others.) There are many good alternatives. Today, polyisocyanurate (a commonly used foil-faced rigid insulation material that is sold under various trade names like Rmax, ACFoam and Thermax, ACFoam Rmax, and ACFoam Rmax) is produced using pentane, a blowing agent its GWP is extremely low (the pentane GPW is around 7). Expanded Polystyrene (EPS also known as beadboard) is also produced by blowing pentane agent. Open-cell SPF, like Icynene is made using water as a blowing agent. Mineral wool, fiberglass and cellulose don't make use of blowing agents in any way. It is important to note it is important to note that XPS or closed-cell SPF provides an array of exceptional performance properties (controlling the flow of water and airflow in the envelope of our buildings) Therefore, when we choose to use for a different type of material, we must tackle these building science issues with care. The main point will be that when it comes time to are insulating our homes to ensure that they consume less energy, and therefore contribute to reducing the effects of the effects of climate change, we must be aware of the type of insulation we select. Insulate your home to a high degree using XPS and closed cell SPF can counteract the effects of that good-willed effort. I invite you to post your thoughts in this post. What will this information mean for your selection in insulation material?

How Insulation Works

Insulation works the same way whether it is for commercial properties or homes. Insulation reduces heat flow from the outside or inside of the house. This is usually done by radiation, convection or conduction.
 

  • Radiation: The loss of heat by electromagnetic waves in the air
  • Convection is the loss of heat by the transmission of heat to liquids or gases.
  • Conduction is the transfer of heat from one solid object into another.

Spray Foam Insulation: What is it and how does it work?

Spray polyurethane foam (SPF) is a chemical product made by mixing polyol resin and isocyanate. The foam is formed when the mixture of the two substances comes into contact with surfaces. It expands to form a foam that seals, insulates and provides moisture resistance. It forms a continuous barrier around corners, inside walls, and contoured surfaces once it's installed. It is an effective way to keep unwanted air and moisture from cracks, joints, seams, or seams. It comes in two types: closed-cell and open-cell foam. The type of use that you intend to install it will determine the type of foam.

Open-Cell Foam Insulation:


Open-cell foam is composed of small interconnected bubbles that give it a low R-value of R-3.5 to R-4. Open-cell foam is less permeable than closed-cell foam and has lower R values. It can also be used to create a wide range of structures because it is flexible.

Because of its high permeability, it is not ideal for damp areas such as crawlspaces and basements. If you're looking for something more, Spray foam at a low priceIt would be your best choice, even though it is not ideal for tight spaces. It absorbs moisture and loses its R-Value during installation, which reduces its insulation properties.

Closed Cell Foam Insulation:


It has a high R-value between R-6 and R-7 and is therefore great for insulation projects.

It works well at blocking moisture transmission and air sealing, making it very useful for residential and commercial spaces.

This foam is ideal for areas that are susceptible to moisture, such as crawlspaces or basements.

Spray Foam Benefits


1. Reduce Utility Bills

Spray foam insulation is more cost-effective than other materials. It has a higher R value, which can save you up to 30% on your heating and cooling costs.

2. Provides Airtight Seals

Spray foam insulation spreads to cracks and joints in crawlspaces, walls, and attics. It also protects against the elements. Spray foam insulation is extremely resistant to water and provides an airtight seal.

3. It is impermeable to water

It can be used in areas that are susceptible to flooding and moisture, such as crawlspaces or basements. It is unlike other materials that get wet and lose its insulation properties.

4. Protects against the buildup of mold and mildew

It is made from an inert plastic material, so mold and mildew won't grow even after many years.

5. It lasts for years

The product is non-rotten and won't attract rodents or other pests once it has been installed. It can therefore last many years without the need for repairs, replacement, or maintenance. It also keeps its R-value over time as compared to other materials such as fiberglass.

6. Make sure your roof and walls are strong

This product will fill up your roofs and walls, strengthening them in a way no other insulation material can.

7. Keeps out contaminants

Because the foam provides an airtight seal, you and your family don't have to deal with pollen or dust. This means that you can spend less money on HVAC systems and keep your costs low.

Spray Foam Common Questions

 


Spray foam insulation is a cost-effective way to retain heat, coolness, or add reinforcement. Spray foam insulation also provides protection against the elements, stability, pest control, weatherproofing and weatherproofing. It is easy to see why people are unsure about spray foam's use in certain situations.

We have collected some of your most frequently asked questions regarding spray foam use and tried to answer them.

How many square footage does a spray-foam kit cover? 


Spray Foam Kits are available in different sizes. These can range from the size an aerosol bottle to 55-gallon drums. A single cubic foot of liquid close cell insulation, properly mixed, will expand to 35 cubes. It can expand more than 30x in liquid. Open-cell insulating Foam can expand 130x their size in liquid.

Is there a waterproof spray foam? 

Spray foam may be waterproof for some purposes, but not all. Open-cell foam is not waterproof and it is not water-resistant. Although closed-cell foam can be waterproof, it is not water-resistant. Only the high-density close-cell foams are truly waterproof.

Is 2 inches of spray foam enough? 

While 2 inches of spray-foam is sufficient for certain situations when using a particular foam type, it is not the standard for sufficiency. For walls using closed-cell foam, 2 to 3 inches is considered sufficient. For walls using open-cell foam, it is necessary to have at least 2 inches. Closed-cell foam for walls is recommended at 4 to 5 inches. For roof spraying, open-cell foam ceilings and roof spraying, it should be 6 to 10 inches.

How much does spray on foam insulation cost? 

Spray foam insulation cost varies by thickness and is usually broken down per square feet. Open foam spray foam can be found at a cost of $1.50 to $1.50 for each square foot. Closed-cell insulation is between $2.50 to $3.

Spray foam: Is it worth it? 

spray foam school

Spray foam insulation saves a lot of money and is energy efficient. Closed-cell insulation has a dense structure, which can be applied to walls and ceilings. It can serve a number of purposes including waterproofing, temperature retention, structural stabilization, and reinforcement. The open-cell spray is a cheaper option. It expands rapidly, filling in the cracks and crevices fast. However, it's not water-resistant and vapor-resistant. This makes it highly effective only when there's no moisture. Its sealing power also acts as a powerful barrier against pests and insects getting into your home.

Spray foam is a common product used in both residential and industrial structures. Spray foam can be applied to nearly any substrate. You should avoid filling too much, which could cause expansion damage.

Get more information on spray foam insulation.

Can I apply spray insulation myself? 

Spray foam kits may be purchased to allow you to apply the spray foam yourself. The spray foam solution is composed of two chemicals (isocyanate & polyol), which both require specific temperatures to remain viable and stable for application. Many spray kits include a built-in indicator, which can be used to denote when the temperature has dropped too low.

Spraying insulation requires some 'non-starter rules'. It shouldn't be applied in moist areas or at temperatures below 50F. For the safety of those applying spray foam, it is important to wear gloves, goggles or breathing apparatus.

Learn how you can use a spray foam barrel set.

How long can spray foam insulation stay off gas? 

An SDS (safety Data Sheet) will be provided by every manufacturer along with the product. This document will provide information about the time that spray foam should be kept clear. Spray foam emits gases and fumes that can be toxic to humans. The area to be sprayed should be cleared by the party performing the work, and then vacated for 24 hours.

Spray foam insulation may be a breeding ground for mold. 

Spray foam insulation offers a number of benefits, including its resistance to moisture. Mold can grow from high levels of moisture because it needs moisture to thrive. Spray foam insulation can be used to prevent mold growth. Spray foam insulation prevents mold growth. Spray foam insulation decreases the potential for mold growth because it keeps moisture out of the area it covers.

Can mice eat foam insulation? 

Spray foam insulation has been proven to not contain food for mice. Mice are capable of digging at objects and following the path of least resistance to get into homes. However, tighter sealing of the attic and walls reduces the possibility of mice getting in. Spray foam is not a problem if the mice have already entered the structure. Theoretically, mice can bite and claw at the spray foam. But it could be harmful to their health, which might cause them to stop.

Spray foam: Is it worth the cost? 

It doesn't really matter if the work is done professionally or by yourself. You could be spending several thousand dollars to get the project completed. Now that you have this information, add it up to your monthly energy bills. Also, calculate any potential pest control and repair costs. If you can break down the expenses by month  you will find that your spray foam insulation costs will be less than the other expenses. It is possible that this will take up to six months, depending on how complicated the project is. But it is likely that the upfront costs of spray foam insulation installation will soon be paid for.

The Spray On Roof Coating System



Polyurea foam roof coatings are the first component of spray polyurethane foam-based (SPF) roofs, a popular commercial roofing system for flat and low slope facilities. They provide very high resistance to thermal expansion and are available as a liquid or solid spray. The spray coating is an excellent option as it can be applied to surfaces without the need for a high heat source.


As the spray is a good choice for flat and low slope roofs, the SPF-CO system is used on flat roofs and is a good choice for a spanking new roof as it is suitable for many roof types. The spray can roof coating is also a good choice for flat roofs.

The SPF system uses a special resin to coat the roof after it has been created. The resin will harden in around two hours, and then the foam and moisture barrier will start to cure. After this period the roof coating will start to harden, and then be ready for a coat of primer. This allows for very little time for any roof leaks to show.



The SPF system also provides excellent protection and is available in different grades. A grade 5 roof is tough and can take a beating from a heavy storm, and still be protected and have a life of around 20 years. The grade 3 system is a good choice for a residential roof, can give a 25-year life to a roof, and is tough enough to hold up to wind, rain, hail, and snow.

The SPF system is also available in roll-on, and roll-off versions. The roll-on version allows a very quick, and easy application to a roof, and is ideal for flat roofs, low slopes, and other flat roofs. The roll-off version is a variation of the roll-on system and is a good choice for low slope roofs, where the primer will start to harden at the edges, and need a final coat to be complete. It is also a good choice for low-slope roofs, as the SPF-CO system is a good choice for low slope roofs.


The SPF system is available with and without the primer, which allows the user to create a roof coating without the need to coat a large area, so the user can control the coverage area. The SPF-CO system comes with primer, which is ideal for areas that are difficult to coat.
