Who we are

Discover how we put people, customers and our mission at the heart of what we do, creating lasting value for the future. By making weatherproofing certain, we help future-proof buildings from design through to installation.

About Effisus

Effisus is an international company founded in Vila Nova de Famalicão, with more than 20 years of experience in external weatherproofing and projects across five continents. Portugal remains at the heart of our product development, certification and technical know-how, while our international presence continues to expand across Spain, the United Kingdom, the United Arab Emirates, Saudi Arabia and other global markets.

Our growth is built on technical expertise, complete systems and local proximity. By working closely with architects, façade consultants, contractors, installers and project teams, we help address the critical details that determine long-term building performance – from joints, interfaces and transitions to complete façade systems.

Our engineers consider the complete solution, including membranes, tapes, accessories, compatibility, detailing and installation, supporting projects from the earliest design stages through to on-site application.

The technical know-how developed in Portugal now contributes to some of the world’s most ambitious projects, including the Red Sea Marine Life Institute in Amaala, the Museum of the Future in Dubai, Hudson Yards in New York and Battersea Power Station in London.

Our mission is simple: making weatherproofing certain.

By getting critical building details right from design through to installation, we help future proof buildings and create lasting value.

Our Solutions

Membranes, tapes and accessories are engineered and tested to work together as complete systems, providing reliable, long-term protection against water, air and vapour. Each solution is selected with compatibility, installation requirements and real project conditions in mind, helping critical building details perform as intended throughout the building’s life.

  • Façade membrane systems designed to protect buildings against water ingress, air leakage and vapour-related risks, while supporting thermal performance and fire safety. Our portfolio includes A1 and B-s1,d0 fire-classified solutions, alongside EPDM membranes and other building envelope sealing systems, rigorously tested and certified to meet relevant international and local standards.
  • High-performance roof and wall sealing systems developed to address critical weatherproofing challenges at joints, penetrations, gutters and other vulnerable interfaces, including demanding applications where long-term durability, movement accommodation and reliable adhesion are essential.

Business

Business Approach

Our sales and engineering teams consider the complete system and work closely with architects, façade consultants, contractors and subcontractors from the earliest design
stages through to site. We accompany every project from the first challenge to the final inspection, helping ensure that each solution is technically sound, correctly applied and built for long-term performance. 

  • Project-specific system recommendation: We assess the specific project detail and recommend the most suitable system for the challenge, supported by clear technical justification rather than a catalogue-based approach.
  • Compatibility checks and technical submittals: Before ordering, we confirm that the selected membranes, tapes and accessories are compatible and provide the necessary technical documentation to support specification and approval.
  • Applicator training and on-site guidance: Our teams support installation through practical training and on-site guidance, helping applicators understand the correct preparation, detailing and application of each system.

Our engineering support from design to site helps clients make informed decisions at every stage, from system selection and compatibility through to installation and inspection.

By addressing critical weatherproofing details correctly from the outset, we maintain a right-first-time focus, helping reduce the risk of failures, remedial work and additional costs later in the building’s life.

Global Presence

At Effisus, local presence is central to how we work. Headquartered in Vila Nova de Famalicão, Portugal, with a presence in Spain, the United Kingdom, the United Arab Emirates and Saudi Arabia, we combine international expertise with local teams and partners to remain close to our customers and their projects.

We believe technical expertise delivers the greatest value when it is accessible locally and at the right time. This approach enables us to provide responsive support while understanding each market’s specific requirements, working practices, regulations and culture. Our strong local presence is complemented by an international reach, with Effisus solutions used in projects across five continents.

Our expertise is reflected in landmark projects worldwide, including Hudson Yards in New York, Battersea Power Station and Portland House in London, the Oceanário de Lisboa, the Museum of the Future in Dubai, the Red Sea Marine Life Institute in Saudi Arabia and Guggenheim Abu Dhabi. These projects demonstrate our commitment to delivering reliable technical performance and dedicated project support across diverse markets, climates and construction environments.

Why Choose Effisus?

Complete systems that work together

Certified membranes, tapes and accessories are engineered and tested as complete systems, helping deliver watertightness, airtightness and vapour control with compatibility built in. Designed for straightforward application and long-term durability, our solutions help reduce complexity on site and improve reliability from the outset.

Engineering support on every project

Our engineers support each project from the first technical challenge through to final inspection. We recommend the most suitable system for each detail, confirm compatibility before ordering, provide technical submittals, and support correct application through training and on-site guidance. Where standard solutions are not enough, we adapt them to the project. 

Long-term value through specialist expertise

Weatherproofing represents a relatively small part of a project’s upfront investment, but failures can create significant long-term risk. By focusing on critical details such as joints, interfaces and penetrations, we help architects specify with confidence, contractors install correctly and developers reduce the risk of remedial work, disruption and additional costs over the building’s life.

Operational efficiency adapted to local needs

Our local presence allows us to respond to the specific requirements of each market and project. Through efficient stock management, reliable supply chains and close coordination with our teams and partners, we help ensure timely material availability, minimise delivery delays and support smooth project execution.
