What Glasopor does

Glasopor AS is a Norwegian manufacturer of foam glass (skumglass) lightweight aggregate, founded in 2002 in Skjåk by Svein Lund and headquartered in Trollåsen (Ås municipality). The company produces a granular fill material made from approximately 99-100% recycled packaging glass collected from Norwegian households, in which glass powder is mixed with an activator and heated to form a cellular structure of roughly 20% glass and 80% air, yielding a bulk density of about 180 kg/m3. Core product fractions are Glasopor 10-20+ (a smaller, higher-strength grade supporting a pneumatic blowing service) and Glasopor 10-60 (a standard grade for general fill, insulation, and drainage), delivered in bulk, 1.5 m3 big-bags, and (since 2025) 50L consumer bags. Production takes place at two electric-powered Norwegian plants — Skjåk (refurbished to electric in 2016) and Onsøy/Fredrikstad (expanded in 2025 with two new electric furnaces and waste-heat recovery, doubling capacity to 280,000 m3/year) — with A1-A3 emissions as low as 6.46 kg CO2-e/m3 at Onsøy.

Glasopor sells almost exclusively into the Norwegian construction and infrastructure market, serving both enterprise/government projects (rail and road infrastructure with Bane NOR, Statens vegvesen, Miljøpakten; large municipal builds with Oslobygg KF; general contractors Skanska, Veidekke, Isachsen Anlegg, Skaaret Landskap; and emerging defense work via Forsvarsbygg and FLO) and SMB/private applications including heritage restoration, foundations, green roofs, and DIY. The revenue model is one-time unit-based sales of physical material across bulk, big-bag, and 50L SKUs, plus a specialized blowing-installation service; pricing is project-negotiated and not publicly disclosed, with distribution via a nationwide dealer network and direct bulk logistics (rail/boat/truck up to 8,000 m3 per coastal shipment).

Glasopor has been a wholly-owned subsidiary of Finnish Foamit Group Oy since 2021, making it part of the largest foam-glass producer in the Nordics (alongside Foamit in Finland and Hasopor in Sweden). The company holds ISO 9001, 14001, 45001, and 50001 certifications, an EcoVadis Gold via its Finnish affiliate (2024), NPS of 73% (2025), and recognition as a 'foregangsbedrift' by the Norwegian Centre for Circular Economy (NCCE, 2026).

Revenue model

1. Foam Glass Aggregate Sales: Glasopor generates revenue from the sale of its foam glass aggregate (skumglass) as a construction material. Products are sold in multiple formats: bulk delivery for large infrastructure projects, large bags (big-bags of 1.5 m³) for medium-scale applications, and 50L consumer bags for tradespeople and homeowners. Revenue is primarily project-based and volume-driven, with repeat customers in infrastructure, construction, and landscaping sectors.

Core offering

Glasopor manufactures and supplies foam glass (skumglass) aggregate produced from recycled packaging glass collected from Norwegian households. The company sells two core product fractions (10-20+ mm and 10-60 mm) in three delivery formats: loose bulk for large infrastructure projects, 1.5 m³ big-bags for medium-scale sites, and 50-liter consumer bags for tradespeople and homeowners. A specialized blowing solution service uses pneumatic trucks to place the 10-20+ fraction in hard-to-access areas such as crawl spaces, historic buildings, and green roofs.

Product overview

Glasopor is a Norwegian manufacturer of foam glass (skumglass) aggregate made from 100% recycled glass packaging. The product portfolio consists of two core foam glass fractions: Glasopor 10-20+ (10-20+mm grain size with superior strength and stability) and Glasopor 10-60 (10-60mm grain size, the most widely used fraction). These are delivered through three main formats: loose bulk for large infrastructure projects, large bags (1.5m³ big-bags) for sites with limited access, and 50L consumer bags for craftsmen and homeowners. Additionally, the company offers a specialized blowing solution (blåseløsning) using the 10-20+ fraction for installation in cavities, crawl spaces, and heritage building restorations. The product serves as lightweight fill, insulation, and drainage material in construction, infrastructure, and renovation projects.

Regional players

• Argex: Belgian producer of expanded clay aggregate for construction and infrastructure lightweight fill applications. Comparable substitute product competing in road, building, and green-roof segments; primarily serves Benelux/France markets rather than Norway.

Direct peers

• Foamit Group (Foamit Oy): Finnish foam glass producer and direct corporate sibling under the same Foamit Group Oy holding company. Produces comparable foam glass aggregate from recycled glass for the Finnish market, sharing technology, R&D, and group-level sustainability positioning with Glasopor.
• Misapor: Swiss manufacturer of foam glass aggregate (Misapor-Material) from recycled glass for lightweight fill, drainage, and insulation in construction. Direct product competitor with overlapping target applications (lightweight fill, road/rail sub-base, green roofs) in the European market.
• Hasopor: Swedish foam glass producer and the third member of Foamit Group Oy. Operates an analogous foam glass aggregate business for the Swedish market using recycled glass, making it a direct Nordic counterpart to Glasopor with shared ownership and strategic alignment.
• Liaver: German manufacturer of expanded glass granulate (Blähglas) made from recycled container glass for lightweight construction fill, acoustic panels, and insulation. Closely comparable recycled-glass aggregate product with overlapping applications and customer segments.

Others

• Sirkel Materialgjenvinning: Norwegian glass and metal packaging recycler that holds collection contracts with all Norwegian municipalities and was Glasopor's previous owner (2006-2021). Key raw-material supplier and historical strategic partner — ecosystem participant rather than direct competitor.

Broad incumbents

• Leca (Saint-Gobain): Established European brand of expanded clay lightweight aggregate under Saint-Gobain, used in road, rail, geotechnical, and building applications. Largest incumbent alternative to foam glass in the lightweight fill market, with broader product portfolio and global reach.
• Knauf Insulation: Global insulation manufacturer with a broad product portfolio including glass mineral wool and other building insulation materials. Adjacent competitor in thermal/acoustic insulation where Glasopor also competes in floor, foundation, and roof applications.
• Dennert Poraver (Poraver): German-based global manufacturer of expanded glass granules for lightweight construction applications. Broader portfolio than Glasopor but competes in the same lightweight fill/aggregate category, particularly in European markets Glasopor may target for expansion.

Emerging players

• Geocell Schaumglas: Austrian/German foam glass producer (Geocell) operating in the same niche as Glasopor with comparable recycled-glass foam glass aggregate for civil engineering applications. A smaller emerging player rather than an incumbent, but with overlapping product positioning in DACH markets.
