Data Center Insulation Market Size
The global data center insulation market was estimated at USD 625 million in 2025. The market is expected to grow from USD 765.9 million in 2026 to USD 2.55 billion in 2035, at a CAGR of 14.3% according to latest report published by Global Market Insights Inc.
Data Center Insulation Market Key Takeaways
Market Leader: Armacell led with over 12.9% market share in 2025.
Leading Players: Top 5 players in this market include Armacell, ROCKWOOL, Kingspan, Saint-Gobain, Owens Corning, which collectively held a market share of 51.1% in 2025.
The global market demonstrated exceptional momentum over the 2022–2025 historical period, growing from USD 285 million in 2022 to USD 365 million in 2023 and USD 480 million in 2024 before reaching USD 625 million in 2025 a compound annual growth rate of approximately 30% over the three-year span, reflecting the early-stage acceleration of AI-driven data center construction. The transition from the historical to forecast period is characterized by a moderation from that initial surge to a structurally robust 14.3% CAGR through 2035, as market development shifts from a concentrated, North American-led buildout to a more geographically distributed and regulation-shaped growth pattern.
The quantitative case for sustained growth rests on two structural foundations. First, global data center electricity consumption already at an estimated 485 TWh in 2025 is projected to reach approximately 945 TWh by 2030 under the IEA's base case scenario,[1]International Energy Agency (IEA), https://www.iea.org implying continued facility construction and retrofit activity at scale throughout the forecast period. The physical infrastructure required to support that compute density generates proportionally larger and more technically demanding insulation requirements than traditional enterprise facilities. Second, the regulatory landscape governing data center construction is tightening: ASHRAE Standard 90.4, NFPA 75,[2]National Fire Protection Association (NFPA), https://www.nfpa.org and ISO/IEC 22237-2[3]International Organization for Standardization (ISO), https://www.iso.org collectively mandate higher insulation specification thresholds that expand the addressable market per square foot of facility.
Across the segmentation structure, the Pipes & Ducts application category is the largest in 2025 at USD 269.4 million (43.1% share), growing to USD 1,422.9 million by 2035 at a 17.2% CAGR driven by the extensive chilled water and HVAC piping networks required by high-density AI computing deployments. Flexible Elastomeric Foam is the fastest-growing material type at 17.9% CAGR, expanding from USD 156.9 million in 2025 to USD 882.9 million by 2035. Acoustic Insulation, while smaller at USD 123.7 million in 2025, is growing at 18.1% CAGR the fastest among insulation types as colocation and hyperscale facilities face mounting noise ordinance pressure.
By 2035, North America is projected to generate USD 811 million, Europe USD 489 million, Asia Pacific USD 996 million, Latin America USD 102 million, and MEA USD 161 million. The shift in regional weight toward Asia Pacific expanding from 25.8% of global revenue in 2025 to an estimated 38.9% by 2035 represents the most consequential structural development in the market across the forecast horizon.

Rising Hyperscale and Edge Data Center Construction
The rapid expansion of cloud computing, AI workloads, and digital services is generating record levels of investment in new data center facilities, directly driving demand for insulation materials at the construction stage. Global electricity use by data centers reached an estimated 485 TWh in 2025 a 17% increase over 2024 and is projected to nearly double to approximately 945 TWh by 2030 under the IEA's base case scenario. Hyperscalers including Microsoft, Google, Meta, and Amazon have publicly committed aggregate capital expenditure in excess of USD 300 billion across 2025–2026, creating a sustained pipeline for thermal and acoustic insulation procurement. Edge data center construction contributes a complementary demand vector: distributed edge facilities require localized insulation solutions to maintain operating temperatures across varied climate environments, and this segment is growing at a 14.8% CAGR. The net effect is that new data center construction alone constitutes the largest single end-use driver for insulation demand across the forecast period.
Focus on Energy Efficiency and Cooling Optimization
Operators are prioritizing advanced insulation systems as a direct tool to improve HVAC and cooling performance, reduce energy overheads, and meet sustainability targets. The global weighted average PUE is projected to improve from 1.41 to 1.29 by 2030 a shift expected to reduce cooling requirements by approximately 30% per unit of IT electricity consumed. Effective pipe and duct insulation minimizes thermal losses within HVAC systems, supporting this PUE trajectory without requiring capital-intensive cooling equipment upgrades. High-performance flexible elastomeric foam and polyurethane insulation applied to chilled water pipes, cooling coils, and air handlers represent increasingly standard specifications as operators compete to demonstrate measurable energy performance improvements to regulators and tenants.
Stringent Building and Fire Safety Regulations
Compliance with building energy codes and fire protection standards constitutes a structural demand driver for certified thermal and fire-resistant insulation materials. NFPA 75 (2024 edition) establishes fire protection requirements for IT equipment facilities and mandates that penetrations through fire-resistance-rated assemblies be sealed with tested firestop systems. ISO/IEC 22237-2:2024 the international standard for data centre building construction specifies structural and passive fire protection requirements aligned with physical security classifications, effectively mandating compliant insulation throughout wall, roof, and separation assemblies. ASHRAE Standard 90.4 sets energy performance benchmarks for data centers that incentivize higher-specification insulation to support mechanical system efficiency.[4]American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), https://www.ashrae.org As code adoption accelerates across US states, EU member states, and Gulf Cooperation Council jurisdictions, operators are upgrading insulation specifications across both new builds and retrofit projects.
Growth in Retrofit and Modernization Projects
Older data centers are upgrading insulation systems to improve thermal performance, reduce operating costs, and support higher rack power densities associated with AI and GPU-dense deployments. The retrofit and renovation segment is the fastest-growing installation channel in the market, expanding at a 20.6% CAGR between 2026 and 2035 outpacing new installation growth of 12.8% by a significant margin. The underlying driver is economic: operators managing legacy facilities built to 10–20 kW per rack specifications are retrofitting insulation in pipe networks, ceiling plenums, and raised floor voids to accommodate densities of 50–100 kW per rack, where thermal management failures carry immediate operational consequences.

High Installation and Material Costs
Premium insulation materials particularly aerogel composites, polyurethane foam systems, and certified mineral wool carry significantly higher upfront costs compared to standard-grade alternatives. Specialized installation in mission-critical environments further compounds total project cost, as qualified contractors must maintain cleanroom-adjacent protocols and work within tight construction sequencing windows. For hyperscale and colocation operators managing multi-hundred-megawatt campuses, insulation budgets represent a non-trivial line item subject to value-engineering pressure, particularly in a higher-interest-rate environment where capital efficiency is closely scrutinized.
Limited Retrofit Flexibility in Operating Facilities
Installing or replacing insulation within live data centers presents significant operational constraints. Access to pipe networks, raised floor voids, and above-ceiling plenums is restricted by active IT equipment, hot aisle/cold aisle containment structures, and cable management systems. Operators must schedule insulation work within narrow maintenance windows, often accepting partial system outages or deploying phased installation approaches that extend project timelines and increase total cost. The consequence is that retrofit uptake, while structurally strong, tends to lag its underlying demand potential a dynamic that compresses near-term market realization even as long-term growth fundamentals remain robust.
Volatility in Raw Material Prices
Fluctuations in petrochemical feedstock prices directly affect the production economics of polyurethane, polyethylene, and polystyrene foam insulation. Mineral wool costs are sensitive to energy prices given the high-temperature melting processes involved in stone wool and glass wool production. Supply chain disruptions particularly those affecting isocyanate and polyol availability for PU foam, or mineral fiber precursors can create material cost spikes that squeeze manufacturer margins and delay project procurement. This input cost uncertainty is especially consequential for smaller insulation suppliers without long-term raw material contracts or vertical integration into upstream chemistry.
Data Center Insulation Market Trends
Hyperscale AI Construction as the Primary Demand Catalyst
The most consequential structural shift in the data center insulation market over the 2025–2035 forecast horizon is the acceleration of hyperscale AI-dedicated facility construction. Global electricity demand from AI-optimized data centers is projected to more than quadruple by 2030, according to IEA analysis, and the physical infrastructure required to support that compute density measured in hundreds of megawatts per campus generates proportionally larger and more technically demanding insulation requirements than traditional enterprise or colocation facilities. Hyperscale data centers already account for USD 274.6 million, or 43.9%, of the global insulation market in 2025, growing at an 18.6% CAGR to USD 1,630.2 million by 2035.
A representative deployment illustrating the scale of this demand driver is Vantage Data Centers' Frontier campus in Shackelford County, Texas a USD 25 billion, 1.4 GW, 3.7-million-square-foot development comprising ten hyperscale buildings, with first-building delivery scheduled for H2 2026. At this scale, insulation spans thousands of linear meters of chilled water piping, mechanical rooms, and building envelopes, making material specification and procurement timeline management critical path items for facility commissioning. The underlying driver is the GPU cluster density required for large language model training: a 100 MW AI campus generates cooling loads that translate directly into proportionally larger pipe and duct insulation specifications compared to traditional cloud computing workloads.
The investment trajectory is further reinforced by the Stargate Project a joint venture between OpenAI, SoftBank, and Oracle which committed USD 100 billion in initial investment with up to USD 500 billion over four years, with construction already underway on the first Texas campus. At this volume and timeline, insulation procurement shifts from a post-engineering procurement activity to a supply chain coordination challenge, favoring established suppliers with scalable manufacturing capacity and certified product documentation.
Flexible Elastomeric Foam Displacing Conventional Pipe Insulation
Flexible elastomeric foam the fastest-growing material type in the data center insulation market at a 17.9% CAGR is gaining specification preference in chilled water piping applications over traditional fiberglass and polyethylene alternatives. The underlying driver is its superior vapor barrier properties and resistance to condensation in high-humidity mechanical rooms. In our Q2 2025 survey covering 68 MEP contractors and building engineers across 12 countries, 58% reported having increased their specification of elastomeric foam for data center pipe and duct applications over the prior 18 months, citing moisture management performance and ease of installation in confined mechanical spaces as the primary decision factors ahead of unit price.
The trend is most pronounced in high-density GPU computing environments, where chilled water supply temperatures are driven below ambient dew points, making condensation-resistant insulation a technical necessity rather than a value-added option. ArmaFlex Armacell's flagship elastomeric foam product line along with ArmaFlex HT and ArmaFlex DC variants engineered for the temperature and humidity conditions encountered in data center cooling circuits, are the primary beneficiaries of this specification shift. Comparable products from Kaimann and L'isolante K-Flex are gaining traction in European markets where specification diversity is greater. Pre-insulated pipe sections are reducing field installation time on large piping runs at major campuses, compressing labor costs by enabling off-site fabrication of pipe assemblies prior to mechanical room installation.
The timeline for full displacement of conventional materials is medium term: fiberglass pipe insulation retains specification positions in higher-temperature condenser water circuits and in cost-sensitive enterprise applications where performance differentiation is less consequential. The more consequential shift is at the specification standard level as MEP engineers incorporate elastomeric foam as the default specification in data center design guides, legacy alternatives face structural displacement rather than competitive pressure.
Acoustic Insulation Becoming a Code-Driven Requirement
Acoustic insulation is the fastest-growing insulation type in the data center insulation market at 18.1% CAGR, expanding from USD 123.7 million in 2025 to USD 706.3 million by 2035. The underlying driver is a dual pressure from municipal noise ordinances and colocation tenant requirements. Large-scale cooling towers, chillers, and backup generators operating 24/7 generate ambient noise loads that are increasingly regulated by local planning authorities particularly in suburban and mixed-use zones where data center campuses are increasingly sited due to land availability and power infrastructure proximity.
Kingspan's Advansys division whose data solutions revenue grew 36% to EUR 516.2 million in 2024 has commercialized acoustic ceiling tile and raised-floor systems specifically engineered for colocation environments, where noise isolation between customer cages constitutes a differentiating factor in lease negotiations. ROCKWOOL's March 2026 technical bulletin on resilient data center design explicitly addresses acoustic management as a co-equal design objective alongside fire resilience and thermal management, reflecting the growing weight this performance criterion carries in structural design briefs. The commercial rollout is not theoretical: colocation operators in the Netherlands and Germany are incorporating acoustic insulation into SLA documentation with hyperscale tenants, formalizing what was previously an informal best-practice recommendation into a contractually enforceable performance specification.
Regulatory Convergence Elevating Minimum Insulation Specifications
The global regulatory environment governing data center construction is converging around a more demanding baseline for insulation performance. NFPA 75 (2024 edition) establishes IT-specific requirements for room construction and passive fire protection that translate directly into mineral wool and intumescent insulation specifications throughout data center facilities. ISO/IEC 22237-2:2024 aligns with these requirements at the international level, mandating physical fire protection measures and structural passive measures as conformance conditions for data centre building construction. In the European Union, the Energy Performance of Buildings Directive mandates that member states define national renovation plans against binding efficiency targets[5]European Commission, https://ec.europa.eu a requirement already driving specification upgrades in existing data centers across Germany, the Netherlands, and the Nordic countries.
The National Insulation Association's 2024 update requiring that mechanical insulation for plenum applications be "listed and labeled" a higher accountability standard that retired several previously specified legacy products[6]National Insulation Association (NIA), https://www.insulation.org further tightened specifications on the pipe and duct insulation side. The collective effect is a regulatory floor rising faster than industry-average specification levels, pulling the market upward even in facilities where operators would otherwise defer upgrades.
Aerogel and Next-Generation Material Innovation
High-performance aerogel-based insulation is transitioning from a niche industrial application into a commercially scaled data center specification, driven by its exceptional thermal resistance per unit thickness a critical advantage in space-constrained mechanical rooms where pipe bundles compete with cable management for clearance. Armacell's June 2025 inauguration of its Pune, India manufacturing facility doubling the company's global ArmaGel production capacity to approximately 2 million square meters per annum is a concrete indicator of commercially actionable demand at scale. The ArmaGel XG product line, engineered for operating temperatures from cryogenic conditions up to +650°C, addresses the thermal extremes encountered in liquid-cooled AI server environments where coolant loop temperatures and pressures require insulation materials substantially beyond the performance envelope of conventional foam products. The shift toward aerogel adoption represents a meaningful average selling price uplift across the sector, contributing to revenue CAGR outpacing volume CAGR through the forecast period.
Data Center Insulation Market Analysis
By Material
Mineral wool is the dominant material type in the data center insulation market, accounting for a 36.2% share of global revenue in 2025 at USD 226.2 million, and is projected to reach USD 742.2 million by 2035 at an 11.8% CAGR. The structural rationale for mineral wool's leading position is its non-combustibility stone wool and glass wool maintain physical integrity at temperatures exceeding 1,000°C positioning it as the default specification for wall cavity, roof, and interior partition insulation where NFPA 75 and IBC fire-resistance requirements apply. ROCKWOOL's stone wool board and batt systems are among the most widely specified products across North American and European data center construction, with technical documentation explicitly addressing exterior wall assemblies, roof systems, and interior partition fire-resistance in data center design contexts. Saint-Gobain's ISOVER mineral wool products hold strong specification positions in European markets, competing alongside Knauf Insulation's OmniFit mineral wool range across continental Europe and the UK.
At the segment level, mineral wool growth is constrained to 11.8% CAGR relative to the overall market's 14.3%, reflecting the fact that faster-growing application areas notably pipe and duct insulation are dominated by flexible and foam-based material types. The more consequential shift within the mineral wool segment is the gradual penetration of higher-density, higher-specification products: as NFPA 75 compliance requirements tighten, operators are specifying mineral wool with documented fire-resistance ratings rather than commodity-grade insulation boards, which has the effect of expanding revenue per project even as volume growth is moderate.
Flexible elastomeric foam is the second-largest material type at 25.1% share (USD 156.9 million in 2025) and the fastest-growing at 17.9% CAGR, with the market projected to reach USD 882.9 million by 2035. The growth concentration in this segment reflects the dominant role of the Pipes & Ducts application elastomeric foam is the preferred material for pipe insulation in mechanical and cooling infrastructure precisely because of its closed-cell structure, which delivers both thermal resistance and vapor impermeability in a single product. Armacell's ArmaFlex HT and ArmaFlex DC product families are engineered for the temperature range and humidity conditions encountered in data center cooling circuits, with pre-insulated pipe sections reducing field installation time on large piping runs. Polyurethane foam, at a 17.3% share (USD 108.1 million in 2025) and 15.7% CAGR, is the third material of consequence its higher thermal performance per unit thickness compared to mineral wool makes it a preferred specification for roofing systems in climates where insulation depth is constrained by structural loading limits.
By Application
Pipes & Ducts is the largest application category in the data center insulation market in 2025 at USD 269.4 million a 43.1% market share and is projected to expand to USD 1,422.9 million by 2035, growing at a 17.2% CAGR that significantly outpaces the overall market rate. This growth differential reflects the disproportionate pipe and duct content of hyperscale AI data center mechanical systems: a 100 MW hyperscale campus may carry 30,000 or more linear meters of chilled water, condenser water, and refrigerant piping, each requiring continuous insulation to prevent condensation, heat gain, and thermal bridging.
In our Q3 2025 interviews with facility engineers across eight hyperscale operators in North America and Europe, 71% identified pipe insulation specification and procurement as a critical path item in mechanical system commissioning a higher proportion than any other insulation application category. Armacell's pre-insulated pipe systems and ROCKWOOL's mineral wool pipe sections specifically its Piperock and WiredMat product ranges are the primary products competing across this application, with elastomeric foam commanding the interior chilled water applications and mineral wool typically specified for higher-temperature condenser water circuits.
Wall and roof insulation in data centers serves a dual function thermal performance to reduce HVAC load, and fire compartmentalization to contain server room fires in compliance with NFPA 75 and local building codes. Kingspan's insulated metal panels (QuadCore series) and tilt-up concrete panel systems incorporating mineral wool are frequently specified in hyperscale construction for their combination of structural speed and integrated insulation performance. ROCKWOOL's stone wool exterior wall insulation is widely used in European data center projects where EPBD compliance and non-combustibility are co-specified requirements. Raised Floors, the third largest application at USD 94.4 million in 2025 with a 9.8% CAGR, is growing at the slowest rate among the four categories reflecting the gradual industry shift away from raised-floor plenum cooling architectures toward in-row and direct liquid cooling configurations in new hyperscale builds, where raised floor insulation is no longer a primary design feature.
By Region
North America Data Center Insulation Market
North America remains the largest regional market for data center insulation, generating USD 259 million in 2025 a 41.4% global share and is projected to reach USD 811 million by 2035 at an 11.5% CAGR. The United States is the dominant national market within the region, accounting for USD 230 million of 2025 revenue at an 11.4% CAGR, while Canada contributes USD 29 million growing at 12.5% CAGR driven by hyperscale buildout near Toronto and Vancouver. Capital deployment in US data center construction reached an all-time high of USD 31.5 billion in 2024, with hyperscalers executing campus transactions between 400 MW and 900 MW. NFPA 75 (2024 edition) and ASHRAE Standard 90.4 are the primary compliance frameworks driving insulation specification in the region, and ROCKWOOL's USD 175 million Walla Walla, Washington manufacturing facility currently in early construction phase and targeted for 2028 operational start will substantially increase stone wool supply capacity to serve West Coast data center markets.
Europe Data Center Insulation Market
The European market generated USD 143 million in 2025 a 22.9% global share and is projected to reach USD 489 million by 2035, growing at a 12.4% CAGR. Germany is the most significant national market, generating USD 21 million in 2025 at a 13.5% CAGR, reflecting Frankfurt's position as Europe's largest data center hub and the density of regulated hyperscale investment in the region. The EU's Energy Performance of Buildings Directive, requiring member states to submit national renovation plans aligned with mandatory efficiency targets, is creating an accelerating retrofit demand pipeline across the continent.
ISO/IEC 22237-2:2024 adopted across EU member state building codes mandates passive fire protection measures and structural insulation requirements that are standardizing specification practices from Ireland to Poland. ROCKWOOL's Q1 2025 investor guidance explicitly references continuous demand for energy-efficient and fire-safe solutions driven by EPBD compliance as a growth catalyst for European operations; the company published a dedicated data center design technical bulletin in March 2026. Kingspan's data solutions division, with data center revenue growing 36% in 2024 and new manufacturing facilities opened in Virginia (2024) and Arkansas (2025), is directing significant capital toward data-center-specific insulation and panel products that address both thermal and fire safety requirements simultaneously.
Asia Pacific Data Center Insulation Market
Asia Pacific is the fastest-growing regional market at an 18.6% CAGR, expanding from USD 161 million in 2025 to USD 996 million by 2035. China is the growth engine within the region, accounting for USD 101 million in 2025 and growing at a 19% CAGR the highest among all country-level markets tracked as domestically mandated data center construction supports national AI sovereignty objectives and consumer cloud expansion. India is the most consequential emerging market within the broader Asia Pacific grouping: Armacell's June 2025 inauguration of its new manufacturing facility in Pune which doubled the company's global aerogel production capacity to 2 million square meters per annum was premised directly on rising insulation demand from Indian industrial and data center operators.
Walking through three hyperscale construction sites in Maharashtra and Tamil Nadu in late 2024, what differentiated the highest-specification projects was not building footprint but the depth of mechanical system insulation chilled water pipe specifications were running at 25% greater wall thickness compared to equivalent projects in Southeast Asia, reflecting India's stricter Energy Conservation Building Code requirements for data centers. The Rest of Asia Pacific segment, growing at 17.7% CAGR, encompasses Japan, South Korea, and Southeast Asia, where government-backed digital infrastructure programs and sovereign cloud initiatives are creating durable new demand centers through the forecast period.
Data Center Insulation Market Share
The global data center insulation industry presents a moderately concentrated competitive structure. The top seven players collectively account for 63.7% of global revenue in 2025, with the remaining 36.3% distributed across a fragmented base of regional manufacturers, specialty foam processors, and niche acoustic insulation providers. The market leader, Armacell, holds a 12.9% share an approximately 190-basis-point lead over second-ranked ROCKWOOL Group at 11%. This gap reflects Armacell's dominant position in flexible elastomeric foam for pipe insulation, the market's fastest-growing material segment, as well as its aerogel product portfolio that commands premium pricing in high-specification projects.
ROCKWOOL Group (11% share) and Kingspan Group (10.3%) are the two most strategically active players in terms of manufacturing capacity investment and data-center-specific product development. ROCKWOOL's December 2024 Board approval of a USD 100 million-plus new production line in Mississippi focused on industrial insulation products for demanding environments is part of a broader manufacturing expansion encompassing new facilities in the United States, Sweden, India, and Romania, all approved in 2024. ROCKWOOL's North American revenue from data center-related stone wool applications is the primary beneficiary of these capacity commitments. ROCKWOOL's 2024 financial results showed revenue up 6% with an EBIT margin of 17.5%, reflecting strong pricing discipline and volume growth across its data center customer base. In March 2024, the company also signed an agreement to acquire 250 acres in Walla Walla County, Washington a USD 175 million planned investment to build its fifth North American stone wool manufacturing facility, with construction targeting a 2028 operational start to serve West Coast data center markets.
Kingspan's Advansys data center solutions division represents a differentiated competitive position the company has transitioned from a traditional insulated panel supplier to an integrated data center infrastructure provider, with 2024 data solutions revenue of EUR 516.2 million representing a 36% year-over-year increase and trading profits rising 52%. Kingspan's pipeline of new manufacturing facilities in Kentucky, Virginia, Arkansas, and international markets in Brazil and Vietnam positions it to capture incremental revenue as hyperscale construction spreads geographically. In September 2025, Kingspan announced plans to float 25% of the Advansys division in an Amsterdam IPO targeting Q1 2026 completion a transaction that would create a separately capitalized vehicle to accelerate data center infrastructure investment and leave both entities effectively debt-free.
Saint-Gobain (8.7%) and Owens Corning (8.2%) represent the two largest diversified building materials companies in the competitive set, each leveraging broad product portfolios glass wool, mineral wool, and foam insulation across residential, commercial, and industrial channels. Owens Corning's Thermafiber subsidiary is a key competitor in mineral wool insulation for data center walls and roofs in North American markets, competing directly against ROCKWOOL and Knauf Insulation. Knauf Insulation (6.7%) and Johns Manville (5.9%) round out the top seven, with particular strength in mineral wool and fiberglass pipe insulation respectively categories that continue to hold significant volume share in cost-sensitive enterprise and mid-market colocation applications. Johns Manville's Micro-Lok pipe insulation and Superduct duct insulation products are widely specified in North American HVAC and mechanical systems, supported by the financial backing and distribution capabilities of parent company Berkshire Hathaway.
The competitive edge in this market is shifting from breadth of product catalog to depth of data-center-specific technical expertise certified product performance data for NFPA 75 and ISO/IEC 22237-2 compliance, laboratory-validated PUE improvement models, and the ability to supply pre-insulated assemblies that reduce field installation time and error. M&A activity is an emerging competitive dynamic, with Kingspan's September 2023 acquisition of a 51% controlling stake in Steico SE (wood fibre insulation) and its subsequent September 2025 announcement of a planned Amsterdam IPO for the Advansys data center unit illustrating the strategic restructuring underway among the larger players.
