Lindab is an international group that develops, manufactures, markets and distributes products and system solutions primarily in steel for buildings and indoor climate. With TightVent Europe, we learn more about the process of building airtight and energy efficient buildings; we fine-tune our product range by networking with suppliers confronted with the same issues. Our ambition is to transfer this knowledge all the way to building owners, architects/consultants, construction companies and workers. Lindab_wesimplify
MEZ-TECHNIK is a worldwide operating family business known for a wide range of innovative solutions and services for high end commercial air duct systems. We work together with consultants, air duct manufacturers, installers, duct cleaners and energy efficiency companies. MEZ offers manufacturing products, installation materials, chemical products, software solutions and air duct cleaning equipment to the market. Since the revolutionary invention of the MEZ-FLANGE-SYSTEM to connect rectangular ductwork by a flange system, we constantly push and change the market and it’s methods of manufacturing and installation on the behalf of better and more efficient rectangular air duct systems. As exclusive representative of AEROSEAL LLC, our sealing technology currently transforms the ductwork process chain to the next most effective and efficient level which you can reach in air duct systems today again. With our unique sealing technology we care about the retrofit of existing ventilation systems in Europe, in the same way we do for new constructions and reduce leakage of air duct systems to nearly zero including all components of a system. By doing this, we can provide a high benefit in terms of IAQ improvement and CO2 reduction in the world. download

ACIN instrumenten founded in 1965, 30 people, is developer, manufacturer and supplier of a wide range of measurement and control equipment for the physical properties of air. One of its main products are air pressure control valves for the gas safe zone in naval vessels. Within Tightvent we are best known for the FF-mk2 launched in 2011 and successor of the FlowFinder, the first zero pressure compensated air flow meter on the market (1986). In cooperation with TNO we developed and launched the AirTightnessTester, the ATT (patent TNO) for a quick check of envelop airtightness using the ventilation system of the house. We also launched in 2021 the new VentiFlow-mk2, a passive flowhood with a patented flow straightener for air flow measurements up to 100m3/hr, supply and exhaust on almost all types of valves used in domestic ventilation. Since 2020, we also have a new 99.9% airtight measurement and calibration lab containing our measurement tunnel for volume flow and to check blowerdoors and our ATT. In 2022 we aim to be ISO17025 accredited for our volume flow measurements. Finally, in cooperation with LeakWorkx, we have developed a system called UltraGraphyx, to search for and ´photograph´ cracks and fissures in structures using ultrasound.
Since 1989, BlowerDoor GmbH has been a pioneer in the fields of airtightness, especially airtightness measurements, and BlowerDoor product design in Europe. Synergies in engineering, product development and training have made the Minneapolis BlowerDoor a high quality device for air tightness measurements all over the world. BlowerDoor GmbH actively supports TightVent to achieve a good and durable quality in building air tightness as one important criterion to reach the ambitious goals of the Energy Performance of Buildings Directive (EPBD) recast.
Eurima is the European Insulation Manufacturers Association. Eurima members manufacture mineral wool insulation products. We actively support TightVent to develop knowledge and application of efficient airtightness solution for a successful implementation of the recast of the EPBD. This requires a good coordination between strong insulation and well-functioning ventilation in order to guarantee both energy efficiency and good indoor air quality.
Soudal NV is Europe’s leading independent manufacturer of sealants, PU-Foams and adhesives. The company, established in 1966, proudly remains family owned. Soudal serves professionals in construction, retail channels and industrial assembly and has 45 years of experience with end-users in over 100 countries worldwide. Since sealing, bonding and insulating is our business, we actively support the Tightvent platform. And with 7 manufacturing sites on 4 continents and 35 subsidiaries worldwide, we hope to contribute to a wide-scale implementation of nearly-zero energy buildings.

The Buildings Performance Institute Europe (BPIE) is an independent, non-profit organisation based in Brussels. BPIE supports the development of ambitious but pragmatic building-related policies and programs at both EU and Member State levels. We timely drive the implementation of these policies by teaming up with relevant stakeholders from the building industry, consumer bodies, policy and research communities. With the TightVent Europe Platform, our ambition is to play a key role in implementing policies on building and ductwork airtightness, bearing in mind ventilation needs.
Heralded as the “world’s biggest urban climate and energy initiative” by Commissioner Miguel Arias Cañete, the Covenant of Mayors for Climate & Energy brings together thousands of local and regional authorities voluntarily committed to implementing EU climate and energy objectives on their territory.New signatories now pledge to reduce CO2 emissions by at least 40% by 2030 and to adopt an integrated approach to tackling mitigation and adaptation to climate change.
