SCHLÜSSELBAUER Geomaterials

What SCHLÜSSELBAUER Geomaterials does

SCHLÜSSELBAUER Geomaterials GmbH is an Austrian private limited company headquartered in Gaspoltshofen, Upper Austria, that manufactures construction insulation materials from 100% recycled container glass. Founded in 2002 as part of the SCHLÜSSELBAUER group, the company operates a single production facility producing three core products: GEOMATERIALS Schaumglas (foam glass aggregate), GEOMATERIALS Blähglas (expanded glass beads), and GEOMATERIALS RED Blähglasschotter (RED expanded glass gravel). The closed-cell foam glass process creates a bulk material that combines thermal insulation (lambda 0.08 W/(m·K)), load-bearing capacity, capillary breaking, drainage, and frost protection in a single product, allowing it to replace multiple conventional foundation layers (cleaning layer, frost protection, insulation, capillary break) in one installation step.

The company sells exclusively to the construction sector, serving residential, commercial, industrial, municipal, and infrastructure projects. Reference projects include the Erste Campus Vienna headquarters (DGNB Gold/ÖGNI Platinum), Andermatt Swiss Alps Resort (1.8 billion CHF development), ÖBB Koralmbahn railway, METRO St. Pölten, and various passive-house residential builds achieving heating consumption as low as 12 kWh/(m²·a). The go-to-market is channel-mediated: more than 80 building material distributors across 15 European countries (Germany, Austria, Switzerland, Italy, Netherlands, Belgium, Poland, Slovakia, Slovenia, Denmark, Ireland, UK, Luxembourg, Romania, Czech Republic) carry the products, supported by regional sales managers who provide technical consultation to architects, engineers, and contractors.

Revenue is generated through hardware sales of insulation materials; pricing is handled through direct inquiry with sales representatives or distribution partners and is not publicly disclosed. The company has 11-50 employees and has positioned itself in the sustainability-certified construction segment, holding the Österreichisches Umweltzeichen (Austrian Eco Label, renewed 2024 for four years) and an EPD per ISO 14025/EN 15804+A2 for its Schaumglasschotter SGS 10-60 product. No funding rounds, M&A activity, or AI/ML capabilities are disclosed.

Core offering

SCHLÜSSELBAUER Geomaterials manufactures three families of construction insulation and lightweight-fill materials from 100% recycled container glass: GEOMATERIALS Schaumglas (closed-cell foam glass granules used as load-bearing thermal insulation under foundation slabs), GEOMATERIALS Blähglas (ultra-light expanded glass beads for thermal/acoustic insulation under screeds and in cavities), and GEOMATERIALS RED Blähglasschotter (expanded glass gravel for road/path stabilization and water-storage systems). Each product combines multiple conventional construction-layer functions in a single installed layer.

Product overview

SCHLÜSSELBAUER Geomaterials produces high-quality construction materials entirely from recycled glass. The product portfolio consists of three core products: GEOMATERIALS Schaumglas (Foam Glass) serves as a load-bearing thermal insulation under foundation slabs; GEOMATERIALS Blähglas (Expanded Glass) provides lightweight thermal and acoustic insulation as an alternative to EPS screed; and GEOMATERIALS RED Blähglasschotter (RED Expanded Glass Gravel) offers weight-reducing properties for water storage systems and road construction stabilization. All products are designed for both new construction and renovation projects, emphasizing environmental sustainability through recycling and high-performance insulation properties.

Products and services

• GEOMATERIALS Schaumglas (Foam Glass) High-thermal-insulating, load-bearing bulk granular fill made from 100% recycled container glass, used as a single combined layer (thermal insulation, capillary break, drainage, frost protection, and load-bearing fill) under foundation slabs in residential, commercial, and public buildings.
• GEOMATERIALS Blähglas (Expanded Glass) Super-lightweight, dimensionally stable beads made from recycled glass, used as a loose or bound thermal and acoustic insulation fill under screeds, in floor beams, and in cavities between floors, marketed as the mineral alternative to cement-bound EPS screed.
• GEOMATERIALS RED Blähglasschotter (RED Expanded Glass Gravel) Lightweight expanded-glass gravel with high dynamic-load absorption and water-storage/water-regulation properties, used as a base layer in road and path construction on low-load-bearing soils and as a structural component of water-storage systems.
