SIGA

What SIGA does

SIGA is a Swiss specialty manufacturer of high-performance adhesives, tapes, membranes, and primers used to construct air and weathertight building envelopes. Founded in 1966 and headquartered in Ruswil, Switzerland, the company operates through three Swiss corporate entities (SIGA Services AG, SIGA Cover AG, and SIGA Manufacturing AG) and serves construction professionals — architects, builders, contractors, and installers — across more than 20 countries, with direct sales/marketing offices in the United States (Chicago and Roseville) and a UK regional headquarters in London. Its product portfolio is organized around four core categories: facade membranes (Majvest), adhesive tapes (Wigluv, Fentrim, Rissan), vapor control layers (Majrex with proprietary Hygrobrid technology and Majpell), and moisture protection membranes (Wetguard), supported by accessory primers (Dockskin), sealants (Meltell, Primur), and double-sided tapes (Twinet, Sicrall, Corvum).

The company's core technology is built on proprietary adhesive chemistry and membrane engineering, including Hygrobrid variable vapor diffusion, primerless adhesion to masonry and concrete, cold-temperature application down to -10°C (14°F), and repositionable self-adhered weather barriers that eliminate mechanical fasteners. These products are designed as an integrated system rather than standalone items, allowing the company to address demanding specifications such as Passive House airtightness standards (e.g., documented 0.36 ACH @50 blower door test results) and LEED-certified commercial builds.

SIGA runs a sales-led go-to-market motion targeting construction professionals through regional sales representatives, specialist dealer networks across 18+ countries, and a direct e-commerce webshop. Revenue is generated through one-time transactional sales of physical building materials with no recurring or subscription component. The company supplements direct sales with AIA-accredited lunch and learns, Passive House building envelope hands-on training, and jobsite training programs, which double as both lead generation and switching-cost mechanisms that create installer and specifier loyalty. Pricing is not publicly disclosed but is consistent with a premium specialty building materials positioning.

Core offering

SIGA manufactures non-toxic adhesives, membranes, and tapes designed to create air- and weathertight building envelopes for zero energy loss buildings. Its product range spans vapour control layers, diffusion-open facade membranes, high-performance adhesive tapes, primers, and construction sealants sold primarily to construction professionals and specialist dealers.

Product overview

SIG A offers a comprehensive system of construction products for creating air and weathertight building envelopes. The portfolio centers on four core product categories: facade membranes (Majvest®) for exterior wall protection, adhesive tapes for sealing and bonding (Wigluv®, Fentrim®, Rissan®), vapor control layers (Majrex®, Majpell®) for managing moisture in walls and roofs, and moisture protection membranes (Wetguard®) for timber construction. These are complemented by accessory products including primers (Dockskin® 100, Dockskin® 200), double-sided tapes (Twinet®), sealants (Meltell®, Primur®), and specialized tapes (Sicrall®, Corvum®). The products work together as an integrated system where facade membranes block wind and rain while allowing moisture to escape, vapor control layers prevent condensation within assemblies, and adhesive tapes seal all joints and penetrations for complete airtightness.

Direct peers

• Pro Clima: Pro Clima (Moll bauökologische Produkte GmbH) is the closest direct competitor to SIGA, manufacturing airtightness membranes, vapor control layers, and sealing tapes for the Passive House and high-performance building envelope market in Europe and globally.
• Dörken (DELTA): Dörken's DELTA brand produces high-performance facade membranes, roof underlays, and air/water-resistive barrier systems directly competing with SIGA's Majvest, Majrex, and Wigluv product lines in the European building envelope market.
• ISO-Chemie: ISO-Chemie GmbH manufactures sealing tapes, window connection foils, and airtightness products for windows, doors, and facades — directly comparable to SIGA's Fentrim and Rissan product categories.

Emerging players

• Blowerproof: Blowerproof (Provensal) offers liquid-applied and tape-based airtightness solutions for building envelopes, overlapping with SIGA's sealing and WRB portfolio but with a different (liquid-applied) technology approach.

Broad incumbents

• Sika: Sika AG is a global construction chemicals incumbent offering sealants, adhesives, and facade/roofing systems; it competes with SIGA in the broader weatherproofing and sealing category but at a much larger scale and broader portfolio.
• Tremco CPG: Tremco Construction Products Group offers sealants, weatherproofing, and air barrier systems for commercial building envelopes, overlapping with SIGA's facade membrane and sealing tape offerings.
• DuPont Tyvek: DuPont's Tyvek brand is a leading housewrap and weather-resistive barrier (WRB) product line, directly competitive with SIGA's Majvest facade membranes, especially in the US residential construction market.
• Carlisle Construction Materials: Carlisle is a large US-based building envelope solutions provider offering WRBs, air barriers, and sealants — broadly competing with SIGA's weatherproofing and airtightness portfolio at mainstream commercial scale.
• Bostik (Arkema): Bostik, part of Arkema, manufactures industrial adhesives, sealants, and tapes for construction — overlapping with SIGA's adhesive tape and sealant product lines within a much larger specialty chemicals portfolio.
• Kingspan Group: Kingspan is a global building envelope specialist offering insulation, membranes, and airtightness products; it competes with SIGA's vapor control and WRB categories while operating at significantly larger scale across residential and commercial construction.
