What FOAMGLAS does

FOAMGLAS is a cellular glass thermal insulation brand and business unit of Owens Corning (NYSE: OW), headquartered in the United States, with its Nordic regional entity (FOAMGLAS Nordic AB) based in Hässleholm, Sweden. The company was founded in 1937 and produces a lightweight, pressure-resistant insulation material composed of millions of fully closed glass cells. The product combines non-combustibility, superior compressive strength, guaranteed water and vapor tightness, and a documented 100-year lifespan, making it suitable for demanding applications where leakage, condensation, fire, or heavy structural loads are critical failure modes. The product portfolio spans the core FOAMGLAS® Cellular Glass Insulation board, plus engineered sub-systems including FOAMGLAS® Tapered (for flat-roof drainage), FOAMGLAS® Kompakttag/Compact Roof (fire-resistant terrace systems), FOAMGLAS® Terrace, and Active Roof solutions.

The company serves four primary customer segments: construction and infrastructure (schools, museums, heritage buildings, flat roofs, underground installations), industrial installations (process piping, storage tank foundations, LNG terminals), maritime applications (ship hulls, offshore platforms), and HVAC systems. Notable reference projects include the Sydhavn School in Copenhagen (Denmark), the Enzo Ferrari Museum in Modena (Italy), the Lysekil LNG receiving terminal (Sweden), and The Roundhouse in Camden (UK). FOAMGLAS distributes through direct enterprise field sales with technical service — covering design assistance, detailed measurement, and installation guidance — bundled into every order, supported by regional offices across 16+ European countries plus the UAE, and the FOAMGLAS Academy installer training program. Pricing is quote-based and not publicly disclosed, reflecting the specification-driven nature of the product in industrial and construction applications. FOAMGLAS operates as a wholly owned business unit within Owens Corning following its 2021 acquisition of Pittsburgh Corning's global foam glass insulation business.

Broad incumbents

• Johns Manville (Berkshire Hathaway): Johns Manville is a large, diversified insulation manufacturer offering fiberglass, polyiso, and mineral wool products across construction and industrial markets. It competes with FOAMGLAS in commercial roofing and industrial insulation as part of a much broader building products portfolio.

Emerging players

• Huntsman (Polyurethanes / Icynene): Huntsman produces MDI-based polyurethane systems and spray-foam insulation (including legacy Icynene spray foam) for construction and industrial applications. It is an indirect peer to FOAMGLAS in rigid insulation, particularly where spray application or factory-laminated panels are specified.
• Aspen Aerogels: Aspen Aerogels produces high-performance aerogel-based insulation blankets for industrial, energy, and building applications. It targets the same specification-rich industrial and LNG customer base as FOAMGLAS, with a thinner and lighter alternative that could compete on total installed cost over time.

Direct peers

• Armacell: Armacell is a global manufacturer of engineered foams, including flexible elastomeric and polyethylene foam insulation for HVAC, industrial, and marine applications. It overlaps with FOAMGLAS's HVAC, maritime, and industrial installation segments.
• Kingspan Group: Kingspan is a global leader in high-performance insulated panels and rigid foam insulation boards for roofing and façades. It competes head-to-head with FOAMGLAS in flat-roof and building envelope applications where fire performance and thermal efficiency are specified.
• BASF (Styrodur / Neopor): BASF manufactures XPS (Styrodur) and EPS (Neopor) insulation products serving the same flat-roof, façade, and below-grade applications as FOAMGLAS. While chemistry differs (extruded polystyrene vs. cellular glass), both compete on compressive strength and water resistance for demanding installations.
• Dow (STYROFOAM / XPS): Dow is a major global producer of extruded polystyrene (XPS) insulation under the STYROFOAM brand, directly competing with FOAMGLAS in below-grade, foundation, and flat-roof applications where water resistance and compressive strength are key specification criteria.
• Knauf Insulation: Knauf Insulation produces glass mineral wool, rock mineral wool, and extruded polystyrene insulation for construction and industrial applications. It overlaps directly with FOAMGLAS in commercial roofing, HVAC, and industrial insulation segments.
• ROCKWOOL: ROCKWOOL is the leading stone wool insulation manufacturer, directly competing with FOAMGLAS in non-combustible building and industrial insulation. Both companies target fire-rated roof, façade, and industrial applications with premium, specification-driven sales models.
• Saint-Gobain (Isover): Saint-Gobain's Isover brand is a global leader in mineral wool and foam insulation for construction and industrial markets. It competes directly with FOAMGLAS across flat-roof, HVAC, and industrial insulation specifications, especially in European projects.
