Gefinex

What Gefinex does

Gefinex GmbH is a German manufacturer of polyethylene-based building materials for sound insulation, moisture protection, radon sealing, and floor construction, headquartered in Pritzwalk, Germany. The company operates as a subsidiary of Austrian insulation specialist Steinbacher Dämmstoffe and serves construction professionals (floor layers, screed contractors, tilers), architects and planners, and building material traders across the DACH region. Its portfolio comprises 49 products organized across seven registered brand families: Geficell® (edge strips and impact sound sheets), Gefitas® (sealing and radon protection), Gefidehn® (expansion joint profiles), Geficon® (the "Die Blaue Wanne" composite waterproofing system that bonds monolithically with concrete), Gefibar® (masonry damp courses), steinothan® (PU rigid foam insulation boards), and steinwool® (non-combustible stone wool edge strips). The Geficon® system and the Gefitas® radon-sealing line are the principal technical differentiators versus traditional bitumen-based alternatives.

The company sells through a regional external sales team (Süd, Ost, West, DACH) supported by an application engineer, building material distributors, and a digital presence spanning a five-language website, Google Ads, LinkedIn and Instagram. Trade shows (notably EPF 2026 in Feuchtwangen), the "Baufragen Messenger" expert consultation service for architects, and downloadable technical documentation are the principal demand-generation channels. Pricing is quote-based and not publicly disclosed, with payment terms of 2% skonto on bank transfer or net 14 days. The company holds ISO 9001 certification and operates with two managing directors and a small, named leadership team.

Core offering

Gefinex manufactures and sells polyethylene (PE) and polyurethane (PU) based construction products for sound insulation, moisture protection, radon sealing, and floor construction. The portfolio spans seven product groups — Geficell® edge strips and sheets, Gefitas® sealing membranes, Gefidehn® expansion joint profiles, Geficon® composite sealing ('Die Blaue Wanne'), Gefibar® masonry damp courses, and steinothan® PU insulation boards — sold primarily to construction professionals, architects, and building material traders across the DACH region. Products are positioned as climate-friendly alternatives to bitumen-based sealing systems.

Product overview

Gefinex is a manufacturer of innovative building products specializing in sound and moisture protection for buildings. The product portfolio consists of multiple product lines centered around construction waterproofing and insulation applications: Geficell® edge insulation strips (Randdämmstreifen) in various PE foam and mineral wool variants for sound decoupling and expansion joints; Geficell® sheets/bahns for impact sound insulation, screed underlays, and parquet underlays; Gefitas® sealing membranes for building waterproofing against rising ground moisture with radon protection; Gefidehn® expansion joint profiles for limiting screed field sizes; Geficon® composite waterproofing (Die Blaue Wanne) for foundation slab waterproofing that bonds monolithically with concrete; Gefibar® masonry barrier membrane for horizontal wall sealing; and steinothan® PU insulation boards for floor thermal insulation. All products are developed and manufactured by Gefinex GmbH, a subsidiary of Steinbacher, based in Pritzwalk, Germany.

Partnerships

One partnership is on record.

• Steinbacher DämmstoffecoreStrategic or Co-development Partner · 25 March 2026Steinbacher Dämmstoffe (Austria) is the parent company and strategic partner of Gefinex. The companies collaborate on joint construction projects, combining Steinbacher's insulation expertise (steinodur®) with Gefinex's sealing solutions (Geficon®). A notable example is a residential development in Spittal an der Drau, Austria (2025-2026), where steinodur® SHD 500 ECO foundation insulation was combined with Geficon® composite sealing. Steinbacher also provides the steinothan® PU insulation board brand used by Gefinex.

Scale indicators2 records

Recent moves5 records

Expansion highlights5 records

Direct peers

• Sika AG: Swiss specialty chemicals company with a broad construction sealants, waterproofing and flooring systems portfolio. Comparable because Sika directly competes in construction-grade sealants, damp-proofing membranes, and flooring-adjacent systems sold to trades and specifiers across Europe.
• Rockwool International: Danish manufacturer of stone wool insulation products including edge strips (Randdämmstreifen) for screed applications. Directly competes with Gefinex's steinwool® Randdämmstreifen line and competes more broadly for non-combustible construction insulation specification across Europe.
• Soprema: French-headquartered waterproofing manufacturer producing membranes, sealants and vapor barriers for below-grade and foundation applications. Directly comparable to Gefinex's Gefitas® and Geficon® sealing product lines serving foundation and below-slab moisture protection.
• BMI Group (Braas / Icopal): European roofing and waterproofing manufacturer (including former Braas and Icopal product lines) with bitumen and synthetic membranes. Directly competes with Gefinex in foundation and below-grade waterproofing, and historically represents the bitumen incumbent that Gefinex's PE alternatives target.
• Recticel: Belgian manufacturer of rigid polyurethane foam insulation boards used in floors, walls and roofing. Directly comparable to Gefinex's steinothan® PU floor insulation boards, with overlapping customer segments of construction professionals and building material distributors.

Emerging players

• Steico: German manufacturer of natural wood-fiber insulation and floor underlay products. Comparable as an emerging alternative-insulation specialist selling into DACH construction channels, with overlapping product categories in floor underlay and impact sound insulation.

Broad incumbents

• Kingspan Group: Ireland-based building envelope specialist with rigid insulation boards and waterproofing membrane offerings. Comparable as a broad incumbent competing across thermal insulation and construction membranes with overlapping channels to architects, contractors and distributors across Europe.
• Carlisle Construction Materials: US-headquartered manufacturer of waterproofing membranes, vapor barriers and construction sealants for below-grade and roofing applications. Broad incumbent competitor to Gefitas® and Geficon® sealing product lines, particularly for larger commercial waterproofing projects.
• BASF (Performance Materials / Neopor, Styrodur): Global chemical incumbent whose Styrodur® (extruded polystyrene) and Neopor® insulation products compete with steinothan® rigid foam boards. BASF's scale, R&D resources and broader portfolio make it a relevant incumbent benchmark, though it does not focus specifically on Gefinex's PE-foam sealing niche.
• Tremco / RPM International: Construction sealants and waterproofing manufacturer under RPM International's umbrella. Comparable as a broad incumbent in construction-grade sealants, joint fillers and below-grade waterproofing, serving similar building envelope and architectural specification workflows.
