At AdTech, we have spent years working alongside procurement engineers, plant managers, and refractory contractors across North American markets. The sourcing decisions around ceramic fiber blankets are rarely straightforward. Temperature class, density, binder content, fiber chemistry, and lead time all create a web of tradeoffs that purchasing teams must navigate carefully.<\/p>\n

What Is a 2300F Ceramic Fiber Blanket and Why Does Temperature Rating Matter<\/h2>\n

Ceramic fiber blankets are lightweight, flexible refractory insulation products manufactured from spun or blown alumina-silica fibers. The “2300F” designation refers to the continuous service temperature limit \u2014 specifically 1260\u00b0C (2300\u00b0F) \u2014 above which the fibers begin to undergo excessive shrinkage, crystalline phase transformation, and eventual structural degradation.<\/p>\n

Understanding this rating is not merely a spec-sheet formality. We have seen projects where procurement teams selected a 2300\u00b0F blanket for a furnace operating at 2200\u00b0F peak, only to find that radiant heat zones and hot spots pushed localized temperatures well above that ceiling. The result was premature ceramic fiber shrinkage, increased heat loss through furnace walls, and unplanned maintenance downtime.<\/p>\n

The 2300F classification sits at the mid-range of the ceramic fiber temperature spectrum. Below it are 2000\u00b0F and 2100\u00b0F grades (economical choices for lower-heat processes), and above it are 2600\u00b0F and 3000\u00b0F grades (high-alumina and polycrystalline products for extreme heat environments). The 2300F tier is, without question, the highest-volume selling grade in the US industrial market \u2014 balancing thermal performance, fiber availability, and cost.<\/p>\n

How Classification Systems Vary Between Manufacturers<\/h3>\n

Not all manufacturers use identical rating systems. Unifrax labels its standard 2300\u00b0F product as “Insulfrax S Blanket.” Morgan Thermal Ceramics markets a similar product under the “Superwool Plus” brand for similar service ranges. Some Chinese-origin imports sold through US distributors carry “2300\u00b0F” labels that are calculated using short-term peak exposure rather than continuous service temperature \u2014 a critical distinction that affects long-term performance.<\/p>\n

When we evaluate a blanket’s temperature rating, we look at three factors simultaneously:<\/p>\n

    \n
  • Continuous use temperature<\/strong> (the standard 2300F spec).<\/li>\n
  • Classification temperature per ASTM C892<\/strong> (which defines quality grades).<\/li>\n
  • Linear shrinkage percentage at rated temperature<\/strong> (should be under 2% over 24 hours per ASTM test).<\/li>\n<\/ul>\n

    Major Ceramic Fiber Blanket Manufacturers Based in the USA<\/h2>\n

    The US ceramic fiber blanket industry is anchored by a small number of large producers and supported by a broader network of regional distributors, toll converters, and specialty fabricators.<\/p>\n

    Tier 1: Domestic Production Leaders<\/h3>\n

    1. Unifrax LLC (Tonawanda, NY)<\/strong>
    \nUnifrax is arguably the most recognized name in North American ceramic fiber production. Their manufacturing facilities in Tonawanda, New York, and Niagara Falls operate continuous fiber-spinning lines producing both standard and specialty alumina-silica blankets. Their 2300F product line includes standard Fiberfrax blankets in densities from 4 to 8 lb\/ft\u00b3. Unifrax also produces bio-soluble fiber alternatives under the Isofrax brand for environments where RCF regulations are a concern.<\/p>\n

    2. Morgan Advanced Materials (USA operations)<\/strong>
    \nMorgan Thermal Ceramics maintains production and distribution infrastructure across the US, including facilities in Augusta, Georgia. Their product portfolio spans 2300F standard grades up to polycrystalline fiber products rated at 3000\u00b0F+. Morgan’s strength lies in technical engineering support \u2014 their applications team frequently collaborates with industrial furnace OEMs to design complete lining systems.<\/p>\n

    3. ITM (Insultek \/ Thermal Ceramics Division)<\/strong>
    \nITM operates as both a manufacturer and a toll converter, taking customer-supplied fiber and processing it into finished blanket form. They are particularly active in the Gulf Coast petrochemical corridor, where demand for high-temperature pipe insulation and expansion joint materials is consistent.<\/p>\n

    4. Almatis and Imerys (Specialty Grades)<\/strong>
    \nFor very high alumina content fiber (70%+ Al\u2082O\u2083) required in 2600F+ classifications, Almatis and Imerys supply raw fiber that US blanket converters process into finished products. These are not mainstream 2300F products, but understanding the raw material supply chain explains why 2300F pricing is less volatile than higher-temperature grades.<\/p>\n

    Tier 2: Regional Distributors with Wholesale Capabilities<\/h3>\n

    Several regional players operate as stocking distributors for major manufacturers and offer value-added services including custom cutting, kitting, and rapid fulfillment. Key names include:<\/p>\n

      \n
    • Refractory Metals Supply<\/strong>\u00a0(Midwest distribution hub)<\/li>\n
    • Global Industrial Ceramics<\/strong>\u00a0(Southeast\/Gulf Coast focus)<\/li>\n
    • Aadvanced Insulations Inc.<\/strong>\u00a0(West Coast distribution)<\/li>\n
    • BNZ Materials<\/strong>\u00a0(Colorado-based; custom fabrication specialty)<\/li>\n<\/ul>\n

      These distributors typically maintain 50,000\u2013200,000 linear feet of 2300F blanket in stock across multiple densities, enabling next-day or 2-day fulfillment for urgent industrial orders.<\/p>\n

      Density and Thickness Selection Logic for Different Industrial Applications<\/h2>\n

      This is where we see the most purchasing errors in the field. Density and thickness are not interchangeable performance levers \u2014 they control different aspects of blanket behavior, and choosing incorrectly creates either waste (overengineering) or failure (underperformance).<\/p>\n

      Understanding Density: 4 lb\/ft\u00b3 vs. 6 lb\/ft\u00b3 vs. 8 lb\/ft\u00b3<\/h3>\n

      Ceramic fiber blanket density is expressed in pounds per cubic foot (lb\/ft\u00b3) or kilograms per cubic meter (kg\/m\u00b3).<\/p>\n

        \n
      • 4 lb\/ft\u00b3 (64 kg\/m\u00b3):<\/strong>\u00a0The lightest standard density. Suitable for backup insulation layers where the primary refractory handles direct heat contact. Also used in residential\/commercial kiln repairs, pizza oven insulation, and low-vibration environments. Lower cost per square foot, lower thermal mass, but also lower compression resistance and tensile strength.<\/li>\n
      • 6 lb\/ft\u00b3 (96 kg\/m\u00b3):<\/strong>\u00a0The most widely specified density in US industrial applications. This density provides a balanced combination of thermal conductivity, compressive strength, and handleability. The majority of furnace lining systems in the chemical processing and metals industries specify 6 lb\/ft\u00b3 as the working layer.<\/li>\n
      • 8 lb\/ft\u00b3 (128 kg\/m\u00b3):<\/strong>\u00a0Higher density means greater fiber packing, which improves erosion resistance, reduces fiber fallout in high-velocity gas streams, and increases the blanket’s ability to hold its shape under mechanical stress. Gas turbine exhaust ducts, rotary kiln seals, and expansion joints frequently call for 8 lb\/ft\u00b3.<\/li>\n
      • 10 lb\/ft\u00b3 (160 kg\/m\u00b3):<\/strong>\u00a0Less common in blanket form; more frequently seen in board or module products. When specified in blanket form, typically used in vibrating conveyor systems or areas with significant mechanical abrasion.<\/li>\n<\/ul>\n

        Thickness Selection Guidelines<\/h3>\n

        Thickness primarily controls total thermal resistance (R-value equivalent for high-temperature applications). The relationship between blanket thickness and surface temperature on the cold face is governed by the material’s thermal conductivity profile, which changes with temperature.<\/p>\n

        Raw Material Chemistry: Alumina-Silica Composition and Its Effect on Performance<\/h2>\n

        The fundamental chemistry of 2300F ceramic fiber blankets is alumina-silica (Al\u2082O\u2083-SiO\u2082). The ratio of these two oxides determines the fiber’s refractoriness, crystallization behavior at temperature, and chemical resistance.<\/p>\n

        Standard 2300F Fiber Chemistry<\/h3>\n

        Most 2300F blankets produced in the USA fall within the following composition ranges:<\/p>\n

          \n
        • Al\u2082O\u2083:<\/strong>\u00a043\u201347%<\/li>\n
        • SiO\u2082:<\/strong>\u00a052\u201356%<\/li>\n
        • Fe\u2082O\u2083 + TiO\u2082 + other impurities:<\/strong>\u00a0<1%<\/li>\n<\/ul>\n

          This near-equal ratio positions the material close to the mullite composition zone (3Al\u2082O\u2083\u00b72SiO\u2082), which provides good thermal stability up to approximately 1260\u00b0C. Beyond this temperature, the amorphous fiber structure begins converting to crystalline mullite and cristobalite phases \u2014 a transformation that causes irreversible shrinkage and embrittlement.<\/p>\n

          High-Alumina Fiber Chemistry (2600F Grade Reference)<\/h3>\n

          For comparison, 2600F-rated blankets typically contain:<\/p>\n

            \n
          • Al\u2082O\u2083:<\/strong>\u00a052\u201355%<\/li>\n
          • SiO\u2082:<\/strong>\u00a044\u201347%<\/li>\n<\/ul>\n

            The higher alumina content delays crystallization onset, which is precisely why higher-temperature grades cost significantly more \u2014 higher-purity alumina raw materials carry a price premium.<\/p>\n

            Effect of Iron Oxide Contamination<\/h3>\n

            Iron oxide (Fe\u2082O\u2083) is a known flux in ceramic systems. Even at <0.5% concentration, elevated iron content accelerates the formation of low-melting glass phases at the fiber surface, reducing effective service temperature. When we evaluate off-brand 2300F blankets for procurement clients, iron oxide content is one of the first data points we request from the mill test certificate.<\/p>\n

            Price Drivers to Monitor in 2026<\/h3>\n

            Several macroeconomic factors are shaping ceramic fiber pricing as we move through 2026:<\/p>\n

              \n
            1. Alumina raw material pricing:<\/strong>\u00a0Bauxite processing costs and alumina availability (particularly from Australia and Guinea) affect fiber production economics. We saw a 6\u20139% spike in alumina-related fiber costs during 2024, and partial normalization has occurred.<\/li>\n
            2. Natural gas costs for fiber spinning:<\/strong>\u00a0Electric resistance furnaces and gas-fired spinning ovens consume significant energy. Regional natural gas pricing in the US Midwest and Gulf Coast directly affects production costs at domestic mills.<\/li>\n
            3. Freight and logistics:<\/strong>\u00a0The return of LTL freight surcharges and diesel cost fluctuations affect delivered pricing meaningfully.<\/li>\n
            4. Tariff environment:<\/strong>\u00a0Section 301 tariffs on Chinese ceramic fiber imports (which carry 25\u201345% duties in most categories) have protected domestic producers and kept pricing relatively firm despite import competition.<\/li>\n<\/ol>\n

              Custom Manufacturing Options: Binder, Needling, and Cut-to-Size Services<\/h2>\n

              Standard ceramic fiber blankets are unbonded or lightly bonded fiber webs. For specialized applications, US manufacturers and fabricators offer a range of value-added processing options.<\/p>\n

              Organic Binder Addition<\/h3>\n

              An organic binder (typically acrylic latex or colloidal silica) is applied to one or both faces of the blanket to improve handleability, reduce fiber fallout during installation, and provide a temporarily stiffer surface for cutting and routing. The binder burns out cleanly during initial heat-up (below 600\u00b0F), leaving the base ceramic fiber structure intact.<\/p>\n

              Applications: Furnace lining installation where overhead or angled mounting creates fiber drape issues; custom-cut shapes that need to hold form during transit.<\/p>\n

              Needled Blanket (Needle-Punched Construction)<\/h3>\n

              In standard blanket production, fibers are held together primarily by entanglement from the spinning process. Needled blankets undergo a secondary mechanical process where barbed needles penetrate perpendicular to the blanket face, mechanically interlocking fibers through the thickness. This dramatically improves:<\/p>\n

                \n
              • Tensile strength (can increase by 3\u20135\u00d7 over standard)<\/li>\n
              • Delamination resistance<\/li>\n
              • Vibration resistance in rotating equipment applications<\/li>\n<\/ul>\n

                Needled 2300F blankets command a 20\u201335% price premium over standard grades but are essential for rotary kiln seals, vibrating furnace hearths, and turbine exhaust applications.<\/p>\n

                Cut-to-Size and Custom Shape Fabrication<\/h3>\n

                Most US fabricators offer waterjet cutting, die cutting, band saw cutting, and CNC routing services for ceramic fiber blankets. Common custom shapes include:<\/p>\n

                  \n
                • Circular gaskets and rings for flange insulation<\/li>\n
                • Custom-width rolls for specialized furnace dimensions<\/li>\n
                • L-shaped or stepped profiles for corner and edge insulation<\/li>\n
                • Pre-formed pipe insulation segments (half-shells)<\/li>\n<\/ul>\n

                  Typical minimum order quantities for custom-cut shapes range from 10\u201350 pieces depending on complexity. Setup fees for new tooling (die cutting dies, CNC programs) typically range from $50\u2013$300 depending on the fabricator.<\/p>\n

                  Flexible Supply Chain Features for US Buyers: Lead Time, MOQ, and Regional Distribution<\/h2>\n

                  One of the most common pain points we hear from procurement managers is inflexibility in ceramic fiber supply chains \u2014 specifically, manufacturers that impose large minimum order quantities or cannot accommodate urgent requests. The US market has evolved significantly in this regard over the past decade.<\/p>\n

                  Regional Distribution Network in the USA<\/h3>\n

                  The US has a reasonably mature regional distribution infrastructure for ceramic fiber products. Major distribution hubs include:<\/p>\n

                    \n
                  • Chicago, IL \/ Milwaukee, WI area:<\/strong>\u00a0Serving the Great Lakes industrial corridor (steel, automotive, foundry applications)<\/li>\n
                  • Houston, TX \/ Baton Rouge, LA corridor:<\/strong>\u00a0Gulf Coast petrochemical and refinery market<\/li>\n
                  • Atlanta, GA:<\/strong>\u00a0Southeastern US furnace and ceramics manufacturing market<\/li>\n
                  • Los Angeles, CA \/ Phoenix, AZ:<\/strong>\u00a0Western US aerospace, semiconductor, and food processing markets<\/li>\n
                  • Pittsburgh, PA \/ Cleveland, OH:<\/strong>\u00a0Rust Belt industrial and metals processing applications<\/li>\n<\/ul>\n

                    Buyers in these regions can typically access stocking inventory within 48\u201372 hours for standard 2300F grades. For buyers in less-served markets (Northern Plains, Mountain West), adding 1\u20133 business days is realistic.<\/p>\n

                    Import Supply Chain Considerations<\/h3>\n

                    Some US buyers source 2300F blankets directly from manufacturers in China (primarily Shandong, Zhengzhou, and Hebei provinces) through direct import or via importing distributors. Key considerations include:<\/p>\n

                      \n
                    • Lead time:<\/strong>\u00a030\u201345 days ocean freight, plus customs processing (add 5\u201310 business days)<\/li>\n
                    • Tariff exposure:<\/strong>\u00a0Current Section 301 tariffs add 25\u201345% to landed cost, significantly narrowing the price advantage versus domestic sources<\/li>\n
                    • Quality verification:<\/strong>\u00a0Third-party inspection (SGS, Bureau Veritas) recommended for first-time import orders<\/li>\n
                    • Minimum order:<\/strong>\u00a0Typically 1 full container (FCL), approximately 2,000\u20134,000 rolls depending on thickness<\/li>\n<\/ul>\n

                      For most US buyers purchasing fewer than 200 rolls at a time, domestic or regional distribution is more cost-effective after accounting for tariffs and freight from Chinese mills.<\/p>\n

                      Certifications, Safety Standards, and Regulatory Compliance in the USA<\/h2>\n

                      ASTM Standards for Ceramic Fiber Blankets<\/h3>\n

                      The primary governing standard for ceramic fiber blanket products in the USA is\u00a0ASTM C892 – Standard Specification for High-Temperature Fiber Blanket Thermal Insulation<\/strong>. This standard establishes:<\/p>\n

                        \n
                      • Density classifications (from 2 to 12 lb\/ft\u00b3)<\/li>\n
                      • Temperature classification grades<\/li>\n
                      • Physical property requirements (tensile strength, specific gravity)<\/li>\n
                      • Test methods for thermal conductivity (per ASTM C177 or C1113)<\/li>\n
                      • Linear shrinkage testing protocol at rated temperature<\/li>\n<\/ul>\n

                        When evaluating a supplier’s product, always request mill test certificates referencing ASTM C892. Any supplier unwilling or unable to provide this documentation should be disqualified from serious consideration.<\/p>\n

                        OSHA and Health Regulations<\/h3>\n

                        Refractory ceramic fibers (RCF) are classified by OSHA under its General Duty Clause and by IARC (International Agency for Research on Cancer) as a\u00a0Group 2B carcinogen<\/strong>\u00a0(possibly carcinogenic to humans). This classification has driven significant regulatory activity in the US:<\/p>\n

                          \n
                        • OSHA PEL:<\/strong>\u00a0The general industry permissible exposure limit (PEL) for nuisance dust (15 mg\/m\u00b3) applies, but OSHA has noted that more protective measures are prudent given IARC classification<\/li>\n
                        • NIOSH REL:<\/strong>\u00a0The National Institute for Occupational Safety and Health recommends exposures be kept below 1 f\/cc (fiber per cubic centimeter) as a precautionary limit<\/li>\n
                        • Refractory Ceramic Fiber Industry Panel:<\/strong>\u00a0The major manufacturers participate in ongoing epidemiological studies; current data suggests exposure-related risk is meaningfully controlled by industry guidelines<\/li>\n<\/ul>\n

                          Bio-soluble fiber alternatives<\/strong>\u00a0(Unifrax Isofrax, Morgan Superwool) have been developed specifically to address health concerns. These fibers dissolve in lung fluid, significantly reducing biopersistence compared to standard RCF. For new installations in manned working environments, we increasingly recommend bio-soluble alternatives for the working layer.<\/p>\n

                          California Proposition 65 Compliance<\/h3>\n

                          Ceramic fiber products sold in California must carry Proposition 65 warning labels due to classification as a potential carcinogen. Any supplier marketing into California without Prop 65 labeling is operating outside compliance.<\/p>\n

                          Ceramic Fiber Blanket vs. Other High-Temperature Insulation Materials<\/h2>\n

                          Ceramic fiber blankets do not exist in isolation \u2014 procurement decisions always involve comparison against competing materials. We regularly field questions about where ceramic fiber blanket truly outperforms alternatives, and where it falls short.<\/p>\n

                          When to Choose Ceramic Fiber Blanket<\/h3>\n

                          Ceramic fiber blanket is the optimal choice when:<\/p>\n

                            \n
                          • Fast furnace heat-up and cool-down cycles are operationally important (low thermal mass)<\/li>\n
                          • Furnace lining weight must be minimized (light-gauge furnace shell designs)<\/li>\n
                          • Complex or curved surfaces require conformable insulation<\/li>\n
                          • Installation time is limited (blankets install in hours vs. castable’s days-long cure)<\/li>\n
                          • Energy efficiency is a priority (low thermal conductivity + low thermal mass = faster cycle, less fuel)<\/li>\n<\/ul>\n

                            When Alternatives May Be Preferable<\/h3>\n
                              \n
                            • Abrasion-intense environments<\/strong>\u00a0(e.g., fluidized bed combustors): Castable refractory resists erosion better<\/li>\n
                            • Molten metal direct contact:<\/strong>\u00a0Dense refractory brick or castable is required<\/li>\n
                            • Very low-temperature applications (<800\u00b0F):<\/strong>\u00a0Mineral wool provides equivalent performance at lower cost<\/li>\n
                            • Extreme precision tolerances in furnace geometry:<\/strong>\u00a0Rigidized ceramic fiber boards may outperform flexible blanket<\/li>\n<\/ul>\n

                              Installation Best Practices and Common Application Errors<\/h2>\n

                              Blanket-to-Shell Attachment Methods<\/h3>\n

                              Ceramic fiber blankets are attached to furnace shells and structures using several methods, each with specific applications:<\/p>\n

                              1. Welded Anchors + Lacing Wire<\/strong>
                              \nThe most common method for horizontal furnace walls. Carbon steel or stainless steel J-anchors or Y-anchors are welded to the shell, and blanket layers are compressed and secured using stainless wire lacing. For 2300F service, 304SS anchors are acceptable; at higher temperatures, 310SS or Alloy 800 is required.<\/p>\n

                              2. Ceramic Button Anchors<\/strong>
                              \nFor temperatures exceeding metal anchor capability on the hot face, ceramic fiber button anchors provide an insulating standoff. These are used in conjunction with stainless steel studs welded to the shell.<\/p>\n

                              3. Module System Installation<\/strong>
                              \nCeramic fiber modules (pre-compressed blanket folded and formed into blocks) are self-supporting once compressed and stud-mounted. Modules are faster to install than layer-by-layer blanket installation and provide inherent expansion compensation.<\/p>\n

                              4. Blanket + Refractory Coating (Rigidizer)<\/strong>
                              \nFor environments with moderate gas velocity, blanket surfaces are coated with colloidal silica rigidizer to prevent surface erosion. This adds minimal thermal resistance while dramatically extending surface life.<\/p>\n

                              Layer Installation Sequence<\/h3>\n

                              For multi-layer 2300F blanket lining systems, the correct sequence matters:<\/p>\n

                                \n
                              1. Install backup layer first (lower density, 4 lb\/ft\u00b3) against the furnace shell<\/li>\n
                              2. Install primary working layer (6 or 8 lb\/ft\u00b3) over backup with joints staggered<\/li>\n
                              3. Offset all joints between layers by at least 6 inches to prevent thermal bridging<\/li>\n
                              4. At corners, fold or miter-cut blanket rather than butting two pieces \u2014 folded corners resist joint opening under thermal cycling<\/li>\n<\/ol>\n

                                Common Installation Errors We See in the Field<\/h3>\n

                                Error 1: Butt-jointing blanket layers without offset<\/strong>
                                \nWhen both inner and outer layer joints align, a clear thermal bridge forms, creating a hot spot that accelerates local degradation.<\/p>\n

                                Error 2: Over-compressing the working layer<\/strong>
                                \nCeramic fiber blanket achieves its insulation value through the air trapped within the fiber matrix. Compressing blanket beyond 25% of its original thickness meaningfully increases thermal conductivity and defeats the purpose of a thicker specification.<\/p>\n

                                Error 3: Using carbon steel anchors in high-temperature zones<\/strong>
                                \nCarbon steel oxidizes rapidly above 900\u00b0F. Corroded anchors lose grip and release blanket sections. Always specify stainless steel hardware.<\/p>\n

                                Error 4: Installing wet blankets<\/strong>
                                \nBlankets stored outdoors or in humid environments can absorb moisture. Installing wet ceramic fiber and immediately firing the furnace causes steam generation within the lining, which can blow out sections of blanket. Dry blankets before installation or allow a controlled slow-fire initial heating.<\/p>\n

                                Environmental and Health Considerations When Handling Ceramic Fiber<\/h2>\n

                                Occupational Exposure Management<\/h3>\n

                                The primary route of ceramic fiber exposure is inhalation of airborne fibers generated during cutting, tearing, and installation. Fibers with diameter below 3 micrometers are respirable and represent the primary health concern. Bulk fiber in blanket form has a much lower release rate than loose fiber or used\/degraded blanket.<\/p>\n

                                Best practice recommendations for US facilities:<\/p>\n

                                  \n
                                • Perform cutting operations using wet methods or in ventilated enclosures when possible<\/li>\n
                                • Place cut ceramic fiber scrap immediately into poly bags \u2014 do not allow it to dry-fragment on the shop floor<\/li>\n
                                • Implement workplace air monitoring if employees install ceramic fiber daily<\/li>\n
                                • Annual medical surveillance (pulmonary function testing) for workers with regular heavy exposure<\/li>\n<\/ul>\n

                                  Disposal Regulations in the USA<\/h3>\n

                                  Ceramic fiber blanket waste is not classified as hazardous waste under RCRA (Resource Conservation and Recovery Act) for standard alumina-silica RCF. Disposal is generally to lined landfills with appropriate waste manifesting. However:<\/p>\n

                                    \n
                                  • California has additional disposal requirements under CalRecycle<\/li>\n
                                  • Some states (notably Minnesota and New Jersey) have stricter guidance on RCF disposal<\/li>\n
                                  • Used ceramic fiber from processes involving hazardous material contact (lead, chromium) may require hazardous waste disposal regardless of the fiber itself<\/li>\n<\/ul>\n

                                    Environmental Product Claims and EPDs<\/h3>\n

                                    Morgan Advanced Materials and Unifrax have published Environmental Product Declarations (EPDs) for select ceramic fiber product lines. These documents, prepared per ISO 14044 and verified by third parties, provide life cycle assessment data including embodied energy, global warming potential, and end-of-life considerations. For LEED projects or sustainability-reporting clients, these EPDs provide documented environmental credibility.<\/p>\n
