ThermaCork
Cork insulation boards. The company provides cork insulation boards and panels for thermal, acoustic, and vibration isolation in building construction. Its expanded cork products are manufactured from cork oak bark using heat and pressure without synthetic adhesives or binders. ThermaCork's natural properties include thermal insulation, sound absorption, vibration damping, and moisture resistance in a single material. Cork harvesting does not harm trees, which regenerate bark for harvesting every 9 years.

BASF Neopor
Graphite-enhanced EPS insulation. Neopor's graphite-enhanced EPS achieves up to 20% better insulation performance than standard white EPS at the same thickness and density. The embedded graphite particles reflect and absorb thermal radiation within the foam structure, reducing heat transfer beyond what air-filled cells alone provide. Neopor is used in exterior insulation finishing systems, foundation insulation, and cavity wall applications across residential and commercial construction. The material maintains standard EPS workability while delivering improved thermal performance per unit thickness.
Owens Corning
Fiberglass insulation and roofing. The company invented fiberglass insulation in 1938 and remains the largest manufacturer of residential and commercial insulation products in North America. Its product range spans fiberglass batts, blown-in insulation, spray foam, and mineral wool for thermal, acoustic, and fire protection applications. Owens Corning's PINK fiberglass brand is one of the most recognized building products, with the color trademarked since 1956. The company also produces composite materials for roofing, infrastructure, and industrial applications.
Rockwool
Stone wool insulation. The company manufactures stone wool insulation made from volcanic basite rock melted at 1,500 degrees and spun into fibers for thermal and acoustic products. Stone wool provides fire resistance to over 1,000 degrees, maintaining structural integrity long after other insulation materials would fail or melt. Rockwool products serve building envelope, industrial, marine, and acoustic applications with moisture-resistant, non-combustible performance. The material is fully recyclable at end of life and the manufacturing process increasingly uses recycled content.
Isover (Saint-Gobain)
Glass wool and mineral insulation. Saint-Gobain's insulation brand produces glass wool and mineral wool products for thermal, acoustic, and fire protection in building construction. Its glass wool is manufactured from up to 80% recycled glass, making it one of the highest recycled-content insulation products available commercially. Isover products range from flexible rolls and rigid boards to blown-in and spray-applied systems for diverse installation methods. The company's multi-comfort building concept uses insulation as part of integrated solutions addressing thermal, acoustic, visual, and air quality comfort.
Recticel Insulation
Polyurethane and PIR insulation. The Belgian company specializes in polyurethane and polyisocyanurate rigid foam insulation boards delivering high thermal performance in thin profiles. Its Eurowall, Eurothane, and Powerwall products address cavity wall, roof, and floor insulation with lambda values among the lowest available. Recticel's vacuum insulation panels achieve thermal performance five to eight times better than conventional materials for ultra-thin applications. The company serves both new construction and renovation markets across Europe with thermal solutions.
Polyisocyanurate Insulation
High-performance foam insulation. Polyisocyanurate foam delivers the highest R-value per inch of any common rigid insulation material used in commercial roofing and wall applications. The closed-cell structure provides moisture resistance and dimensional stability alongside thermal performance that improves at lower temperatures. Polyiso boards are faced with various facer materials including foil, glass fiber, and coated glass for different installation requirements. The material is widely specified in commercial flat roof assemblies and continuous exterior wall insulation systems.
