The European Investment Bank (EIB) has approved a €20 million loan to Aisti, a Finnish manufacturer specializing in bio-based suspended ceiling acoustic tiles. This funding aims to help Aisti increase its production capacity and accelerate its growth in sustainable building materials.
Aisti’s acoustic tiles are crafted from patented wood fibres, providing an eco-friendly alternative to traditional mineral wool tiles. These tiles do not contain mineral wool fibres, meaning they do not release harmful particles into indoor air, making them safer for public and commercial spaces such as schools and offices.
The company plans to build a large-scale production facility in Kitee, Eastern Finland. It is expected to begin manufacturing in the second half of 2026. The funding will enable Aisti to double its planned production capacity to 5 million square metres, supporting growing market demand across Europe and the Nordic region.
Additionally, the loan will support research and development efforts to improve the tiles’ acoustic and fire-resistant properties. These innovations are expected to strengthen Aisti’s market position and promote sustainable construction practices throughout Europe.
This financing is part of the InvestEU programme and uses venture debt: a long-term loan designed for innovative businesses. It aligns with the EU’s goals to reduce greenhouse gas emissions and promote a circular economy.
“Europe’s green transition depends on innovative companies like Aisti,” said EIB Vice-President Karl Nehammer. “Supporting this project helps promote the circular economy and rural development while strengthening Europe’s capacity to produce sustainable construction materials.”
Aisti’s CEO, Mikko Paananen, emphasized that the partnership allows the company to expand faster and more efficiently. “Doubling our capacity helps us offer healthier, lower-carbon alternatives at the market’s scale,” he said.
