This must mean however, that the the inner inch has a REALLY high R-value to bring the total up to 8.2 per inch. Fire resistance The fact that it's a bit over 0.5 BTU in /(hr ft2 F) means it's actually a bit less than R2. Is it any better than other foil-faced polyiso foam? For example, Table 2 below shows the R values for various thickness of fiberglass batt insulation. The material is stable to well over 200°C.”, That seems to address the fire properties of the phenolic foam matrix, but what about the pentane blowing agent? It is currently available only as a foamed-in-place insulation. https://www.greenbuildingadvisor.com/articles/dept/musings/cold-weather-performance-polyisocyanurate, https://buildingscience.com/documents/information-sheets/info-502-temperature-dependent-r-value, still haven't seen a US cost on this material. The air-permeable (e.g., fiberglass or cellulose) insulation must be installed directly under the air-impermeable (e.g., spray foam) insulation.". But the 25mm samples all test in the sixes. I have the most trouble with the flammability performance claimed for Kooltherm. A foam pipe insulation’s R value can tell you a lot about how well the material protects the area from exposure to cold. open-cell foam has an R-value of almost 5. The bubbles are quite small, so Phenolic foam has the highest R-value per inch of any plastic insulation--around R8. The tests must be done on the insulation material alone (excluding any airspace). Comfort control systems, in particular, those that utilize forced air heating & cooling, can create a pressure differential that contributes to energy transfer. For more information on the history of phenolic foam marketing in the U.S., see Phenolic Foam Insulation Revisited. You can also sign up for BuildingGreen’s email newsletter to get a free report on insulation, as well as regular posts from Peter. Michael is right. Poorer quality foam insulation may have a high percentage of closed cells but the cell walls may be of inferior quality and have ‘windows’, or holes, that allow the gas to escape over time. GIC fabricates phenolic foam insulation in a variety of shapes and sizes to meet your exact specifications. Open cell spray foams are between .5 and 1 lbs per cubic foot, and have an R value of 3.0 – 4.0 per inch of insulation. A double-layer of the 30mm goods (60mm = 2.36") probably comes a bit less than the R8.07/inch of the 75mm foil faced samples, but it would be useful to see the curve plotted against temperature. We all know the EPS and XPS are very flammable (just toss a piece on an open fire), but my very empirical test of polyiso form on the same fire only resulter in veey short period of flame, but that was only after being poked with a stick. The Federal Trade Commission (FTC) governs claims about R-values to protect consumers against deceptive and misleading advertising claims. Here is the link (scroll down to see the section I'm talking about): 2015 Vermont Residential Building Energy Standards section 402.2.2.1. What is R-Value? Performance in accordance with ASTM E84/UL 723 for smoke and flame development: Flame Spread Index <25; Smoke Developed Index <450. Online pricing in the U.K. Enclosed existing wall or open new wall cavities. Response to Peter Yost I just received an email from Peter Yost, who forwarded the following response from Kingspan: "Kooltherm R-value is lower at 25mm [1 inch]. But a fabric potholder slows the rate of heat transfer allowing the pot handle to be grabbed even when it is hot. They were designed by the American Society of Testing and Materials (ASTM). And for sure this is not the only instance when the code got the building science wrong or had incomplete and/or conflicting language in different sections. open-cell foam has an R-value of almost 5. This inner layers must be around R-10/inch!! Share on whatsapp. They exhibit good fire resistance according to the British Standard 476 and superior R-value. It should be protected from prolonged exposure to sunlight and water. I would like even more testing and if true its mighty impressive. Just because the code requires that the contractor must install insulation either above or below the sheathing, doesn't mean that the contractor gets to install the insulation in a way that violates other sections of the code. Foam pipe insulation has different insulating factors which are known as R values. • Four densities (4) are available: 2.5# (.15 K factor), 3.75# (.16 K factor), 5.0# (.21 K factor), and 7.5# (.23 K factor). The materials used to create potholders have a much lower thermal conductivity and therefore have a higher thermal resistance. Different materials conduct heat at different rates. It has a high closed cell content and fine cell structure. R-value refers to a particular material’s performance as an insulator and how well it holds up to heat. "2. A higher volume to surface area ratio means less gas escapes. Phenolic foam has been used successfully in insulation systems where moisture resistance is a key issue. The Kootherm insulation in the attic space can be left exposed, since according to code authorities, the insulation qualifies as an ignition barrier. A transformative one, if you ask us. https://www.insulationshop.co/phenolic_rigid_insulation_boards.html As a side note, here in CT there is a company that does spray foam phenolic. Very Kool ! If this slate roofing is ever replaced with asphalt shingles, standing-seam metal roofing, or any type of vapor-impermeable roofing, this unvented cellulose-insulated roof assembly will accumulate moisture and fail! R-value is used to measure materials ability to resist heat or in other words, resistance of a material unit to heat transfer. Its high R-value and low thermal conductivity mean that an end user can buy less insulation and maintain the same performance compared to other common insulation materials. GBA Energy Solutions blogs on the Wilson project, “Tested Wall Assemblies Using Kingspan Kooltherm Insulation Boards in Attics, Crawlspaces, Basements, and other Interior Applications.”, sign up for BuildingGreen’s email newsletter, https://www.just-insulation.com/shop/shop-kingspan-kooltherm-rigid-phenolic-boards.html, https://www.homedepot.com/p/Thermasheath-Rmax-Thermasheath-3-2-in-x-4-ft-x-8-ft-R-13-1-Polyisocyanurate-Rigid-Foam-Insulation-Board-613010/100573703, 2015 Vermont Residential Building Energy Standards section 402.2.2.1, https://www.srgpartnership.com/work/multnomah-county-courthouse, Misleading Energy Reports Used to Sell Spray Foam, R-6.2 per inch for 1-inch samples, and R-8.2 per inch for 3-inch samples — R-values that are. There is a long answer to this, which I will probably do in a separate blog--since how most recent codes treat roof assemblies is complex and inadequate from a building science perspective--but the short answer is yes: the current VT code, in the section for existing homes states (4.1.8): "Roofs without insulation in the cavity and where the sheathing or insulation is exposed during reroofing must be insulated either above or below the sheathing." According to your Comment #27, this section of the code only applies to projects "where the sheathing or insulation is exposed during reroofing.". It offers many advantages, including excellent density and an R-value of 4.8 per inch of thickness, which forms an effective barrier against heat transfer and thus helps you save energy around the house. Poorer quality foam insulation may have a high percentage of closed cells but the cell walls may be of inferior quality and have ‘windows’, or holes, that allow the gas to escape over time. Anyone seeing anything on availability of this product in North America? […] ), [Editor’s note: Phenolic foam rigid insulation was introduced in the U.S. in the 1980s and sold by Beazer East and Johns Manville. If you manage wintertime condensation with an interior air barrier and interior vapor retarder along with drying to the exterior, that is high performance to me. Performance with regard to ignition in accordance with IBC Section 2603.5.7: Approved. 'ow much does it cost The insulation performance is extremely high for the thickness of insulation. City building officials will no l onger accept the widely used 180 - day conditioned R -value figures for affected rigid foam insulation materials, such as extruded polystyrene, phenolic, ployisocyanurate and polyurethane insulation. Other places requiring insulation that can withstand high temperatures. Foam board insulation is easy to use and is a great DIY way to add some insulation. I've been waiting to get my hands on some of this stuff since August. From this expression, it can be observed that the R value is inversely proportional to the heat loss. When measured in the metric equivalent, the unit of measure value would be oC m2 sec/J. Best Wall Insulation R Value. The 1/0 Lb. Expressed mathematically, R value is a measurement that accounts for the heat loss through a given surface area of material exposed to a temperature differential for a given period: In this expression, ΔT represents the thermal differential on either side of the material, S represents the surface area through which the heat is being transferred, t is time, and H is the amount of heat loss. TRYMER Supercel High Density is a closed-cell rigid phenolic foam insulation. Phenolic Foam Insulation Phenolic Foam is manufactured from phenol formaldehyde resin, and is available as either an open or closed cell product. Materials that have lower heat loss have higher R values, and materials with higher heat loss have lower R-value. The NFPA 286 test is the “corner” test for interior applications (for example, see this video). He has been building, researching, teaching, writing, and consulting on high-performance homes for more than twenty years. The reasons for this excellent performance are: • Phenolic foam has a low water vapour permeance and is therefore highly resistant to the passage of water vapour • Phenolic foam has low water absorption which takes place predominantly in the Availability It seems as though we are getting burned, not the insulation!

If they started offering the stuff in the US in 2016, and three years later they don't have any discernible way for customers to buy it, and their sales people aren't interested in talking to potential customers (isn't that their job? I stand corrected. See INSULATION R-VALUES & PROPERTIES for current R-values. It seems plausible that the faces of the material would have more resin and fewer bubbles, or some other mechanical difference due to the manufacturing process, affecting the R-value for thin samples. Does it become R8.2 per inch when the insulation board includes the foil facing? Find and evaluate OEMs, Custom Manufacturers, Service Companies and Distributors. High quality closed cell phenolic foam has at least 90% closed cell content which can produce approximately double the R-value of open cell foams. When is phenolic board insulation going to become readily available? Unfinished walls, including foundation walls. An experienced trainer and consultant, he’s been recognized as NAHB Educator of the Year. It has over 90% closed cell formation, giving it good stability. Although the insulatio values are difficult to believe, I would like to address the fire resistance. That makes some sense to me as well, but is not wholly convincing. R-values (“thermal resistance”) based upon heat flux measurements according to ASTM C 177-04 or ASTM C 518-04 must be reported only in accordance with the requirements and restrictions of ASTM C 1045-01, ‘Standard Practice for Calculating Thermal Transmission Properties from Steady-State Conditions.’ ”. Insulation, in the thermal sense of the word, is all about reducing the rate at which heat flows in or out of an enclosed space. But if you cover that Polyiso with another inch of polyiso, then the first inch of poly-iso is "warmed up" and will have a measurably higher R-value-(R4ish? Loose-fill insulation that compacts or settles to a higher density may become less effective an insulation, dropping its R value. In the U.S., insulating products are labeled with their R value measured in imperial units. This means that the higher the U-value the worse the thermal performance of the building envelope. High quality closed cell phenolic foam has at least 90% closed cell content which can produce approximately double the R-value of open cell foams. Alex Wilson of BuildingGreen has already published a great article on Kooltherm. Phenolic Insulation Review. Of note may be why this product was previously discouraged in its use: http://msdssearch.dow.com/PublishedLiteratureDOWCOM/dh_08ab/0901b803808ab35e.pdf?filepath=styrofoam/pdfs/noreg/179-04129.pdf&fromPage=GetDoc, "Phenolic foam insulation was manufactured and sold into the North American market in the 1980’s Even though it was quite popular with some energy-conscious builders because of its very high R-value, phenolic foam insulation is no longer in production in the United States. The listed R-value for the phenolic foam boards is R-6.7 to R-7.5 per inch; Kooltherm insulation is R-8+ per inch. Gould concludes, “Kooltherm is now my interior rigid insulation material of choice for this type of deep energy retrofit.”. Kingspan Kooltherm Pipe Insulation is the thinnest and most efficient product available for the insulation of pipework in building services / HVAC applications and is suitable for both new build and refurbishment projects in the residential, commercial, institutional, industrial and leisure sectors. Serious corrosion problems of fasteners and steel decks that were in contact with the foam resulted in legal action, and both companies ceased production of phenolic foam in 1992. They are useful as it is a way of predicting the composite behavior of an entire building element rather than relying on the properties of individual materials. The existing roof assembly was pretty typical, until the R-value was beefed up to R-53. It's nice to see a product deliver on its claims. It comes in standard-size 4×8 sheets, and smaller sizes, in many different thicknesses from 1/4 inch to 2 inches. We are using the power of our platform to aid in the mass shortage of critical supplies. A correction It is due to the fact that federal law makes it illegal to sell insulation labeled with R-values determined at a mean temperature other than 75 degrees F. The relevant statute is the Federal R-Value Rule (16 CFR Part 460, “Trade Regulation Rule Concerning the Labeling and Advertising of Home Insulation”). I do not believe polyiso is at R2, ever. TRYMER Supercel Phenolic Insulation is a closed-cell rigid phenolic foam insulation, supplied in the form of large buns for fabrication into pipe shells, curved segments, sheets, tank and vessel coverings, and other shapes for a variety of thermal insulation applications. It did smolder, though. This inner layers must be around R-10/inch!!" Become a GBA Prime member and get full access to GBA articles, enyclopedia, videos, CAD library, and more. Spray foam insulation is a leading type of insulation for a number of different buildings and wall types. For the time being, I have edited the article to reflect this report. All phenolic foam insulation board wholesalers & phenolic foam insulation board manufacturers come from members. Also that particular graph seems to go further than other graphs on this website, even conflict. Performance with regard to vertical and lateral fire propagation in accordance with IBC Section 2603.5.5: Approved. You must be a magazine subscriber to access this feature. The NFPA 285 test is the exterior assembly test (for example, see this video). The materials used to create potholders have a much lower th… Cementitious foam; Phenolic foam; Insulation facings; In addition, there are several reflective-based types including foil-faced kraft paper that seek to reduce energy transfer from radiation by reflecting that energy back to its origin, whether inside or outside of the enclosure. usable in basement? … Read Article. Yes, polyiso can perform at R2/inch @ Keith Gustafson ], Calculating the Minimum Thickness of Rigid Foam Sheathing, How to Install Rigid Foam On Top of Roof Sheathing, Avoiding the Global Warming Impact of Insulation, Calculating the Global Warming Impact of Insulation, Making Healthier, Greener Foam Insulation, Cold-Weather Performance of Polyisocyanurate, Using Rigid Foam As a Water-Resistive Barrier, Intertek Code Compliance Report for Kingspan Kooltherm insulation, He continued, “This approach got us to the right total R-value, highest level of airtightness, and excellent drying potential to the exterior.” The exterior layers of the roof assembly include sheathing boards, building paper, and slates. I too am curious to see how the R-Value changes with temperature and to what extent it is vapor permeable. One of those miracle sponges on TV would go on about how it absorbed (X) times its weight in water. Thanks. Here is a link: Phenolic Foam Insulation Board. Spray Foam R Value Chart Our Phenolic Foam, TRYMER® Supercel Phenolic, is a closed-cell rigid phenolic foam insulation. This article explores what the R values associated with insulation mean, presents the common types of insulating materials, and illustrates the suggested guidelines for what R-value to apply based on the climate zone. Phenolic foams come in varying densities in the range of 35 kg/m³ to 200 kg/m³. I don't like proprietary, i want to know what i am buying, patented is okay since the patent is public knowledge. Molded or expanded polystyrene is commonly called beadboard and has a lower R-value than extruded polystyrene. Being an empirical sort of guy, I decided to torch some Kooltherm. After the first layer of Kooltherm was installed, a worker from American Installations uses the company's innovative cellulose installation system to achieve a dense installation of cellulose in the roof framing cavities. re Phenolic Insulation Boards. Air-impermeable and air-permeable insulation. This is a material test to determine the R-value of an insulation material. Stay up to date on industry news and trends, product announcements and the latest innovations. phenolic foam insulation board. Phenolic foam is one of numerous available varieties of insulation. Copyright© 2021 Thomas Publishing Company. Reg. Poorer quality foam insulation may have a high percentage of closed cells but the cell walls may be of inferior quality and have ‘windows’, or holes, that allow the gas to escape over time. Not buying that non linear R value improvement Phenolic is capable of twice the thermal capabilities of other common insulating materials like cellular glass. ". Aluminum Foil Laminated Phenolic Foam Insulation Board Product Details W.T aluminum foil laminated phenolic foam insulation board is a new type of high-tech composite insulation material. Thanks, Michael, for setting me straight. Where both air-impermeable and air-permeable insulation are provided, the air-impermeable insulation shall be applied in direct contact with the underside of the structural roof sheathing in accordance with Item 5.1.1 and shall be in accordance with the R-values in Table R806.5 for condensation control. 259 phenolic foam insulation board products are offered for sale by suppliers on Alibaba.com, of which other heat insulation materials accounts for 13%, insulation materials & elements accounts for 1%. Exterior applications: must be covered with weatherproof facing. The actual blowing agent is a proprietary mix, with constituents added to — among other things — reduce the flammability of the blowing agent.”. It might be interesting since it need not be covered. It established a new benchmark in R -value requirements for foam insulation. No flame retardants yet exceptional smoke development and flame development numbers; The insulation includes really tiny gas pockets (the smaller the pockets, the less heat flow); and. can the foil faced phenolic product be used as a drop in replacement for polyiso on the interior side of an exterior concrete basement wall, followed by an empty stud wall and drywall? It is lightweight, has good workability and has low thermal conductivity which means thinner insulation for any specified insulation level. https://www.energy.gov/energysaver/weatherize/insulation/types-insulation, Types of Insulation - A Thomas Buying Guide, https://bisresearch.com/industry-report/global-insulation-material-market-2021.html, https://www.energy.gov/energysaver/weatherize/insulation, https://cellulose.org/Cellulose-Insulation-2nd.php?pagename=WhatR-valueMean&dirname=HomeOwners, https://www.bpihomeowner.org/blog/what-does-r-value-mean, https://progressivefoam.com/what-is-r-value/, https://www.norbord.com/na/blog/understanding-r-value-and-u-value/, https://energyeducation.ca/encyclopedia/R-value, https://www.energy.gov/energysaver/weatherize/insulation/insulation-materials, Types of Air Conditioners - A Thomas Buying Guide, The Top Log Homes Manufacturers and Suppliers in the USA, What is MRO and What Does it Stand For? to install and can be cut and shaped to any size with hand tools. Phenolic foamed-in-place insulation uses air as the foaming agent. The interior Kooltherm contributes R-32, and the dense-packed cellulose contributes R-21. This process will be the topic of the next blog on the 81 Chapin Street deep energy retrofit. Find materials, components, equipment, MRO supplies and more. In a world in which climate change is of major concern, understanding insulation R values and how to adequately insulate buildings is one method of reducing energy consumption and the resultant emission of greenhouse gases from the combustion of fossil fuels. Exactly the same as any other sponge but they neglected to mention that part. The slate is still there. Here is a portion of the code that Martin quotes. Insulation is rated based on R-value. Different materials resist heat conduction differently, and that is what R-value denotes. The test methods are: re Dana Aerogel has an incredible R rating per inch, but its well tested, researched, explainable and proven (and very expensive and fragile). R-value (insulation) Vacuum insulated panels have the highest R-value, approximately R-45 (in U.S. units) per inch; aerogel has the next highest R-value (about R-10 to R-30 per inch), followed by polyurethane (PUR) and phenolic foam insulations with R-7 per inch. Foil Facing and R-Value Response to Rick Evans It should be protected from prolonged exposure to sunlight and water. Phenolic board has a slightly higher r-value (higher is better, unlike u-values) and a slightly thinner profile than PIR/PUR boards due to the manufacturing process. This article presented an explanation of the meaning of R values for insulation, as well as the types of insulation and the guidelines for its use by climate zone. But a fabric potholder slows the rate of heat transfer allowing the pot handle to be grabbed even when it is hot. Unfinished walls, including foundation walls for new construction. It is much less combustible than other rigid insulations. For purposes of comparison, it's worth noting that in the United States, Home Depot sells 2-inch thick Rmax polyiso for $0.95 per square foot. Plus, it is a recommended product in the latest BG insulation guide.”. ), then they are a catastrophe. 10+ million models from leading OEMs, compatible with all major CAD software systems. To study and analyze the global Phenolic Foam Insulation Sheetconsumption (value & volume) by key regions/countries, product type and application, history data from 2014 to 2018, and forecast to 2024. Is there a theoretical limit to R-value per inch? In addition, other factors can contribute to heat loss in a building. The 2015 IRC IRC R806.5.1.3. California Do Not Track Notice. Different materials conduct heat at different rates. The thermal resistance or R-value of polystyrene foam board depends on its density. R values are a measure of the thermal resistance of insulating materials, which is their ability to slow down or impede the passage of heat through that material. The PolyPhen® phenolic rigid foam insulation products, have thermal conductivities ranging from 0.17 -.24 Btu in/hr ft 2 and can be used to insulate surfaces operating within the temperature range of -290°F to +250°F (-180°C to + 120°C), and is manufactured to provide optimum thermal performance and flame resistance, low smoke emissions, environmental safety, and efficient cost.
