Dupont Tyvek - Sustainability in the Building Industry.

June 2021

Forta Pro modular solutions with DuPont™ Tyvek® deliver energy efficiency and increase interior comfort.

April 2021 – “Kvarteret Jylland” is a new student accommodation consisting of 350 micro-apartments), located in Kista, Northern Stockholm, Sweden. The project mission was to build modern, sustainable and attractive premises for young people. The Kvarteret Jylland complex (7100 square metres, four buildings) was completed in a short amount of time by the Latvian-based company Forta Pro, that specializes in modular construction solutions based on energy efficiency and sustainability concepts. 178 modules were fabricated and installed. DuPont™ Tyvek® breathable membranes and accessories have been used by Forta Pro for the building envelope to protect the construction from water, air and moisture and to increase the comfort and well-being of the students.

Modular construction is a process that uses off-site, prefabricated building methods. It ensures better construction quality management and less disruption. Projects can be completed up to 50% quicker than traditional construction methods. The pre-engineered structures are manufactured and assembled off-site

in a factory-controlled environment. DuPont building materials provide holistic solutions that fulfill the requirements of this housing project, of modular construction techniques, and improve energy efficiency.

DuPont™ AirGuard® vapour control membranes were used with the internal insulation to deliver superior airtightness. These membranes are extremely resistant, lightweight, flexible and easy to install, they maintain their characteristics over time and help to optimize the building performance. A DuPont™ Tyvek® Tape was used to join the membranes and create a continuous barrier with no leakage.

On the exterior walls, a Tyvek® vapour-permeable and water-resistant membrane provides high performance protection from weather conditions. To create an optimum building envelope, DuPont™ Tyvek® Flex Wrap was used to seal the outer construction penetrations such as pipes and conduits.

Inside, a Tyvek® tape seals around the window frames. With their wide variety of products and world-class technical know-how, DuPont Performance Building Solutions help building and construction

professionals and companies to meet the new and demanding requirements in terms of airtightness and increased energy efficiency.

The Kvarteret Jylland project was challenging in many ways and it was essential to cooperate with our partners for a successful outcome. From the beginning, we rely on partners like DuPont who can assist us throughout the entire process with daily contact, training in our production facility and technical support.
