WOLF GROUP

What WOLF GROUP does

Wolf Group OÜ (formerly Krimelte OÜ) is an Estonian-founded construction chemicals manufacturer established in 1994 that develops, produces, and sells polyurethane foams, sealants, adhesives, coatings, fillers, expanding tapes, and patented application tools. The company operates four production units (Tallinn x2, Libatse, and Gavà, Spain) supported by 400+ employees and serves customers across 70+ export markets through 16 sales branches and regional distribution partners. Its product portfolio is anchored by the Penosil flagship brand (sold in 60+ countries), supplemented by the Olivé professional sealant brand (acquired in Spain, 45+ year heritage) and the Tempsi cement-based construction tile brand, with products ranging from commodity PU foams to differentiated specialty items such as EasySpray low-isocyanate sprayable foam and MEKO-free silicone sealants.

Wolf Group generates revenue through three streams: sales of its own branded products (Penosil, Olivé, Tempsi) via direct sales branches and distribution networks; full-service private label contract manufacturing for "world-renowned brands" covering R&D, production, and logistics; and customized industrial and prefabricated construction solutions. It targets four customer segments — Professional (PRO) contractors, Do-it-yourself (DIY) consumers, Industrial (IND) customers including prefabricated construction, and Private Label (PL) brand owners — and supports these with a multi-channel GTM combining owned sales branches, independent distributors, hardware retail, e-commerce, trade fair presence (BAU, Fensterbau Frontale), and influencer marketing. The business model is quote-based rather than subscription, with sustainability credentials (EMICODE EC1PLUS, French VOC A+, M1, Clean Air Gold, FEICA-based EPDs valid until 2027) forming an increasingly important specification lever for institutional and green-building buyers.

In 2020 the company reported €111.2M in consolidated turnover (up ~11% year-over-year) and €10.5M in operating profit, implying a ~9.4% operating margin. Since then it has reorganized internally (2020-2022 mergers, May 2022 rebranding from Krimelte OÜ to Wolf Group OÜ), entered Canada (2021) and intensified D-A-CH focus (2023), and expanded the product line with patented low-isocyanate, sustainable, and fast-curing foam adhesives. The company is privately held by founders Jaan Puusaag and Jaanus Paeväli with no disclosed external PE/VC backing.

Direct peers

• Soudal: Belgian family-owned manufacturer of PU foams, sealants, and adhesives — the closest scale and product-line comparator to Wolf Group. Both are private, European-rooted specialists in one-component foam with global distribution.
• Selena Group: Polish construction chemicals manufacturer (Tytan brand) producing PU foams, sealants, and adhesives. Closely comparable mid-sized European producer with similar export-heavy business model and overlapping customer segments.
• Den Braven (Bostik / Arkema): Dutch-origin sealants, PU foams, and adhesives manufacturer now part of Arkema's Bostik division. Direct competitor across construction, DIY, and industrial channels with broadly overlapping product range and European heritage.
• Tremco (RPM International): Specialty construction sealants, coatings, and waterproofing business within RPM International's Building Solutions group. Strong overlap with Wolf Group's PRO/IND sealants and coating portfolio serving professional construction.

Broad incumbents

• Sika AG: Swiss-listed global leader in construction chemicals and sealants/adhesives. Overlaps with Wolf Group's sealants and adhesives but also spans concrete admixtures, roofing, and flooring — much larger scale and broad portfolio.
• Mapei: Italian family-owned global leader in construction adhesives, sealants, and chemical products. Comparable product mix in sealants/construction adhesives with a globally recognized brand and far larger revenue base.
• Henkel AG (Adhesive Technologies): German-listed global adhesives giant whose Adhesive Technologies division spans construction sealants and PU foams (e.g., PATTEX/Ceresit heritage). Far larger, multi-segment business with overlapping construction channel.
• Bostik (Arkema): Specialty adhesives and sealants division of Arkema, with strong presence in construction sealants, PU foams, and DIY channel brands. Comparable product portfolio with the breadth and R&D depth of a global chemical major.
• H.B. Fuller: US-listed industrial adhesives and sealants manufacturer with construction and industrial specialty segments. Overlaps in sealants and PU-foam-adjacent chemistries but skewed toward industrial customers rather than Wolf Group's DIY/PRO mix.

Regional players

• Master Builders Solutions (BASF): BASF's construction chemicals subsidiary offering sealants, coatings, and concrete-adjacent products. Comparable in construction sealants/coatings chemistry but primarily serves concrete and infrastructure projects rather than Wolf Group's foam-led portfolio.
