What Isolkappa does

Isolkappa Italia S.r.l. is an Italian manufacturer of expanded polystyrene (EPS) thermal and acoustic insulation products for the construction industry, operating as part of the family-owned Industrie Rinaldi group. Founded in 1985 and headquartered in Battipaglia (Salerno) with a legal registered office in Milan, the company employs approximately 250 people across 10 Italian locations and runs a commercial network of 100 sales agents. Its product portfolio spans graphite-enhanced EPS panels (i-GREY, i-PAN, i-TOP, i-LAYER, i-WIND), thermoacoustic systems (Silence line), ETICS accessories (K-NET mesh, anchors, plasters), lightweighting aggregates (BETONTHERM, MASSLIGHT), and ancillary products (KARONTE cemetery formwork, PIGNATTA slabs, RILEVATI STRADALI). Production relies on Neopor BASF graphite raw material, with proprietary detensionatura (pre-stressed) and elasticizzazione (elasticized) processes, and operates RINA-certified Industry 4.0 facilities with a COREPLA-recognized PEPS recycling platform enabling recycled-content output.

Isolkappa generates revenue primarily through one-time B2B sales of EPS insulation panels, complete ETICS systems, and accessories to building material distributors, construction companies, architects, and individual professional buyers across Italy. Distribution combines a direct sales force of 100 commercial agents with a network of authorized resellers (including long-tenured partners such as Marche Isolanti) and a website catalog that captures quote requests. Pricing is by personalized quote per unit (panel, bag, or linear meter) with no public price list. All products carry CE marking under UNI EN 13163/13499 plus CAM, PSV MIX-ECO, REMADE, ETAG 004, and ETA certifications, making the portfolio eligible for Italian government incentive programs (Superbonus 110%, Ecobonus) and public procurement.

The company's go-to-market leans on content-driven technical marketing (corporate site, technical guides, FAQs), industry event participation (Green Med Symposium, ANIT Congress), earned media (La Repubblica, RaiUno), and brand-building initiatives including the VAMOS docufilm and the Diadora Utility advertising partnership. Isolkappa is a member of ANCE (Associazione Nazionale Costruttori Edili) and a COREPLA PEPS platform partner, and its CEO Giuseppe Rinaldi sits on the board of AIPE (Associazione Italiana Polistirene Espanso). Revenue is not publicly disclosed; the company is a privately held subsidiary of Industrie Rinaldi with no institutional or private equity investors disclosed in source materials.

Core offering

Isolkappa manufactures and sells EPS (expanded polystyrene) thermal and acoustic insulation panels and complete ETICS (External Thermal Insulation Composite System) packages for the construction industry. The portfolio spans graphite-enhanced insulation panels (i-GREY, i-PAN, i-WIND, i-LAYER, i-TOP, i-GES), thermoacoustic systems, complementary accessories (K-NET mesh, anchors, profiles, plasters), and lightweight concrete additives (BETONTHERM, MASSLIGHT). Products are sold under both a standard line and a CAM-compliant ECO line using recycled-content certified EPS.

Product overview

Isolkappa produces a comprehensive portfolio of EPS (expanded polystyrene/sintered polystyrene) thermal insulation products and systems for the construction industry. The offering includes insulation panels (i-GREY, i-PAN, I-LAYER, I-WIND, I-TOP series), thermal acoustic solutions (i-GREY ECO Floor, i-GES G ECO Silence systems), accessories for external thermal insulation composite systems (K-NET mesh, starting profiles, corners, expansion joints), and lightweighting products (BETONTHERM beads, PIGNATTA, PANI blocks). The product range follows a dual-line architecture: the standard product line and the ECO line with CAM (Minimum Environmental Criteria) certified products containing recycled materials, certified with PSV and REMADE marks. Products serve multiple building insulation applications: external thermal insulation systems (cappotto), cavity insulation, internal insulation, roof/floor insulation, and civil engineering applications.
