The demand for polyisocyanurate insulation in the European Union is projected to grow from USD 5.0 billion in 2025 to approximately USD 7.6 billion by 2035, recording an absolute increase of USD 2.6 billion over the forecast period. This translates into total growth of 52.9%, with demand forecast to expand at a compound annual growth rate (CAGR) of 4.3% between 2025 and 2035. FMI’s verified research on advanced composites and performance materials indicates that the overall industry size is expected to expand by nearly 1.5X during this period, supported by rising demand for energy-efficient building materials, expanding applications in commercial roofing and continuous insulation systems, and developing uses across residential sheathing, industrial facilities, and appliance insulation in European construction and renovation activities.
The industry is being strengthened by stricter building energy codes requiring higher thermal efficiency, escalating energy costs fueling insulation retrofit demand, and growing adoption of polyiso as a leading thermal insulation solution due to its superior R-value per inch, moisture resistance, and fire safety properties. Between 2025 and 2030, demand is projected to increase from USD 5.0 billion to USD 6.1 billion, adding USD 1.2 billion in value, which represents 44.3% of the total growth expected through 2035. This period will be shaped by increased demand for continuous insulation systems meeting thermal bridging standards, rising use of polyiso in commercial roof installations, and growing adoption of foil-faced rigid boards across residential and commercial wall applications replacing conventional cavity insulation. Manufacturers are advancing product portfolios with non-halogenated flame retardants, bio-circular polyiso formulations, and high-performance spray foams designed to comply with stricter European building directives.

The segment derives significant competitive advantages from established production infrastructure, decades of field performance validation, and the ability to meet substantial volume requirements from major commercial roofing and insulation contractors without reformulation constraints limiting production flexibility. The segment's dramatic declining share through 2035 reflects the category's rapid evolution toward TCPP-free formulations, which grow from 23% in 2025 to 30% in 2035, as environmental regulations increasingly restrict halogenated flame retardants and sustainability-conscious architects and developers prioritize non-halogenated polyiso aligned with green building standards and occupant health objectives.
Competitive advantages:
EU polyiso insulation sales are advancing steadily due to increasing commercial construction activity in European markets, growing building energy retrofit requirements, and rising specification of continuous insulation systems. The industry faces challenges, including MDI and polyol feedstock price volatility affecting production costs, flame retardant regulations potentially restricting TCPP usage, and competitive pressure from alternative insulation materials including mineral wool and XPS. Continued innovation in non-halogenated flame retardants and bio-based polyol technologies remains central to industry development throughout the forecast period.
The rapidly accelerating development of TCPP-free and non-halogenated flame retardant polyiso formulations is fundamentally transforming insulation chemistry from traditional organohalogen flame retardants to environmentally responsible alternatives enabling effective fire protection with reduced environmental persistence and human health concerns, delivering sustainability credentials previously unattainable through conventional TCPP-based polyiso products. Advanced formulation platforms featuring phosphorus-based non-halogenated flame retardants, intumescent additives, and mineral filler systems allow producers to create sustainable polyiso with equivalent fire resistance, thermal performance, and building code compliance comparable to TCPP-containing products while meeting increasingly stringent European chemical regulations under REACH and addressing green building material requirements. These chemistry innovations prove particularly transformative for environmentally conscious building owners, LEED and BREEAM certified projects, and health-focused institutions where halogen-free materials prove essential for indoor air quality objectives and sustainable building certification supporting occupant wellness priorities.
Modern polyiso manufacturers systematically incorporate bio-based polyol feedstocks, recycled content MDI, and circular economy principles that deliver reduced carbon footprint, renewable content certification, and lifecycle environmental improvements comparable to traditional petroleum-derived polyiso formulations. Strategic integration of bio-polyols derived from vegetable oils, recycled PET polyols, and mass balance certified bio-circular MDI optimized for polyiso chemistry enables producers to position sustainable insulation products as legitimate low-carbon building materials where embodied carbon directly determines green building acceptance and lifecycle assessment performance. These sustainability improvements prove essential for premium market positioning, as net-zero building and embodied carbon reduction initiatives demand material transparency, renewable content documentation, and lifecycle carbon accounting supporting European Green Deal objectives and building sector decarbonization targets. Companies implement extensive sustainability assessment programs including environmental product declarations (EPDs), lifecycle carbon footprint studies, and renewable content verification targeting superior environmental performance including 10-15% bio-circular content, reduced GWP blowing agent adoption, and recyclability enhancement throughout product design and manufacturing operations.
European building codes and energy efficiency standards increasingly prioritize continuous insulation assemblies featuring unbroken thermal barriers with polyiso rigid boards eliminating thermal bridging through wall studs, structural elements, and cladding attachments that differentiate high-performance building envelopes through comprehensive heat flow control and energy code compliance. This continuous insulation trend enables manufacturers to drive market growth through exterior wall insulation, commercial roofing over metal decks, and below-grade foundation applications resonating with energy-conscious developers seeking code compliance without compromising building design flexibility. Polyiso applications prove particularly important for continuous insulation segments where high R-value per inch drives material selection, with polyiso's 6-6.5 R-value per inch enabling thinner wall assemblies compared to alternative insulation materials requiring greater thickness for equivalent thermal performance. The development of specialized continuous insulation systems, integrated air barrier technologies, and attachment methods minimizing thermal bridging expands manufacturers' abilities to create comprehensive building envelope solutions delivering consistent thermal performance with validated energy modeling through thermal imaging verification and whole-building energy simulation supporting architect specification.
