Ice Tight

What Ice Tight does

Eisedicht GmbH (trading as Ice Tight / EISEDICHT) is a German manufacturer of self-adhesive air sealing sleeves and adjacent sealing systems for building envelope penetrations, headquartered in Dörentrup, Germany. The company was founded by Michael Eisenhauer in November 2000 from a 9 m² cellar operation based on his practical experience as a drywall builder, and now operates from a ~5,600 m² facility including an in-house quality testing laboratory, showroom and training room. Its product portfolio centres on the world's first patented self-adhesive air sealing sleeve with grommet, and has expanded into multiple penetration seals, pitched and flat roof penetrations, gas/radon seals (GasSTOP), heat-resistant seals (HOTSchott), TPU-based folding membranes (TPU-DICHT), corner, facade and installation seals, plus accessories such as connection tapes, primers and silicone sprays. Core production capabilities include 2-component injection molding, slitting, relamination and flexographic printing, using Tyvek, Alu-Butyl and Vlies-Butyl carrier substrates with age-resistant adhesive coatings.

The business sells sealing products directly to construction industry professionals — drywall builders, roofers, facade contractors and building envelope specialists — primarily through direct sales, via in-house consultation, and through specification databases (Heinze, Ausschreiben) used by architects and specifiers. The go-to-market is sales-led, supplemented by regular trade fair presence (BAU, DACH&HOLZ, FensterFrontale, SHK Essen), accredited training programmes (with Wöhler, Steico and FLiB; dena-recognised) and an active social/newsletter funnel. Pricing is quote-based rather than publicly disclosed, products are not sold through public e-commerce, and the company does not appear to use distributor or VAR intermediaries beyond the specification platforms.

Eisedicht has remained privately held and owner-managed since inception, with no disclosed venture or private equity investment. Distribution is stated across 26 countries with a cumulative customer base of 2,500+ and headcount of 40+ as of 2025, when the company celebrated its 25th anniversary and unveiled a next-generation sealing sleeve at BAU Munich. Products carry third-party certifications (TÜV Proficert ISO 9001, Passive House Institute, TÜV/GTÜ/MPA Braunschweig) and are positioned for compliance with DIN 4108 Part 7 and EnEV 2014.

Broad incumbents

• Sika: Swiss specialty-chemicals company offering sealants, adhesives, and waterproofing systems for construction. Comparable on chemistry-based sealing solutions, but a much larger incumbent with broader geographic and product reach.
• Soudal: Belgian manufacturer of sealants, adhesives, and PU-foams for construction and industry. Competes with Eisedicht in building-envelope weatherproofing but at much broader scale and via different chemistry-led solutions.
• Bostik (Arkema): Global adhesive manufacturer serving construction, packaging, and industrial assembly, including sealant and tape products for building envelopes. Comparable adjacency in adhesive technology and sealing applications but much larger and diversified.
• Würth: Global leader in fastener, tool, and construction-chemical distribution, including sealing tapes and grommets. Broader incumbent that offers competing airtightness SKUs via trade catalogs but does not specialize in this niche.
• Henkel: Global industrial and consumer adhesives company whose construction-chemicals division competes in sealants and building envelope solutions. Closely comparable in adhesive-manufacturing NAICS overlap but operates at vastly larger scale.
• illbruck (Tremco CPG): European building envelope brand offering sealing tapes, membranes, and airtightness systems as part of a broader construction-chemicals portfolio owned by Tremco CPG. Overlaps with Eisedicht's penetration-sealing range, but competes across a much wider product set.
• tesa (Beiersdorf): Manufacturer of high-performance adhesive tapes including construction and building envelope sealing tapes. Adjacent competitor in self-adhesive sealing products with much broader R&D, brand, and distribution resources.

Direct peers

• SIGA: Swiss manufacturer of high-performance airtight and windtight sealing tapes, sleeves, and membranes for building envelopes. Most direct global competitor to Eisedicht's core product category with overlapping distribution in DACH-region construction trades.
• pro clima (Moll Bauökologische Produkte): German pioneer of intelligent airtight building envelope systems including sealing tapes, sleeves, and grommets. Direct competitor serving the same drywall, roofer, and energy-efficiency consultant customer base across German-speaking markets.
• Dörken (DELTA): German manufacturer of DELTA-brand membranes, vapour barriers, and airtightness accessories for building envelopes. Direct competitor in high-performance sheeting and sealing products sold through German construction trade channels.
