What Ampack does

Ampack AG is a Swiss specialty manufacturer of building-envelope solutions, founded in 1946 and headquartered in Rorschacherberg, Switzerland, with a wholly-owned German subsidiary (Ampack Bautechnik GmbH) in Lörrach. The company produces membranes (roof underlays, formwork membranes, wind seals, vapour checks, vapour barriers, moisture barriers, trickle protection, radon barriers), adhesive technology (acrylic tapes, butyl rubber tapes, nail seals, liquid adhesives, sleeves, primers), and noise-protection products (heavy foils, vibration elements, felt strips). Its proprietary technological foundation is monolithic membrane technology combined with a 3D prefabrication service (launched June 2025) that delivers millimetre-precise, ready-to-install roof-membrane kits from installation plans, and it integrates DuPont's Tyvek substrate technology across multiple SKUs. Core certifications include ISO 9001 (since 1996), CE marking to EN 13859-1:2014, ISCC, EC1 Plus, French VOC A+, AgBB, and HFA seal-tightness, which collectively act as tender prerequisites in European commercial construction.

The company operates a B2B go-to-market targeting construction professionals (roofers, façade installers, builders) through a network of authorised retailers across five countries — Switzerland, Germany, Austria, France, and Italy — supported by localised websites, a retailer-locator tool, and country-specific phone support. Revenue is generated via hardware sales of building-envelope products with non-publicly-disclosed pricing; the model relies on channel partners rather than direct-to-consumer sales. Backed by 10- and 20-year warranties covering materials, conversion costs, and installation costs, Ampack positions itself as a full-system supplier rather than a single-product vendor. Recent product launches (non-combustible range, 3D prefabrication, ISCC-certified Ampatex Eco 5 extra) and the publication of a 2026 sales brochure indicate active catalogue refresh and continued investment in sustainable and fire-safety product segments.

Broad incumbents

• Würth Group: Global leader in fastening, assembly, and construction materials with a large adhesives, sealants, and tapes portfolio. Competitor in adhesive technology products for construction professionals, with much broader product range and scale.
• Sika AG: Swiss-listed global construction chemicals heavyweight with broad portfolios in sealants, adhesives, waterproofing, and roofing membranes. Overlaps with Ampack's adhesive/sealant and waterproofing lines but at vastly larger scale and broader application scope.
• BMI Group: Major European roofing systems provider offering membranes, pitched and flat roof solutions. Overlaps with Ampack's roof membrane portfolio but as a full roofing system supplier rather than a focused envelope specialist.
• Saint-Gobain: Global building materials giant with extensive roofing, insulation, and sealing product lines. Competes broadly with Ampack across multiple product categories but as a diversified incumbent rather than envelope specialist.

Others

• DuPont Tyvek (building envelope): Owner of Tyvek building envelope membrane technology and current technology partner to Ampack. Adjacent role as both supplier of materials Ampack uses and a broader competitor in weather-resistant membranes.

Direct peers

• Soprema: French-headquartered specialist in waterproofing membranes, vapor barriers, and sealing systems for roofs and building envelopes. Competes directly with Ampack in membrane and sealing products across European markets.
• Tremco (RPM International): European construction sealants, weatherproofing, and building envelope solution provider. Comparable membrane and sealing product overlap with Ampack in commercial and residential construction.
• Bostik (Arkema): Global adhesives and sealants manufacturer with construction-industry focus, including tapes and sealing products for building envelopes. Direct overlap with Ampack's Ampacoll adhesive technology range.
• pro clima (Moll bauökologische Produkte): German specialist in weather-resistant membranes, vapour checks, and airtight sealing systems for high-performance building envelopes. Direct competitor in the same construction-professional channel across DACH.
• SIGA: Swiss manufacturer of high-performance airtight and windtight sealing systems, tapes, and membranes for building envelopes. Closest direct competitor to Ampack, with overlapping DACH distribution and a similarly focused product portfolio.
