Modern new website in three languages
Zilenzio rebuilt its website from the ground up and asked us to realise the visual identity created by Note (design studio). We implemented the site on WordPress with Gutenberg as the core page builder, and extended it with a bespoke Zilenzio theme and a set of custom components that go far beyond the standard toolkit.
Key features
- Product information management syncing data in three languages.
- Product catalogue with custom Gutenberg blocks and a React-based filtering UI.
- Matching list and filter components for Insights and Case Studies.
- A custom grid layout system built on Gutenberg, enabling the Zilenzio team to create new pages that automatically follow the 12-column design grid while keeping content flexible and easy to manage. See the Sustainability page for a great example.

Building Trust, Delivering Results
The project was a success on several important levels. With a very short lead time, trust quickly became the foundation of the work. From day one, we showed that we could be relied upon to deliver, which gave everyone the confidence to move forward without hesitation.
This trust also shaped the collaboration with Note, the design studio. Working with a new partner meant adapting to each other’s ways of working, but because the relationship was open and straightforward, it became a smooth and constructive process. The cooperation added value and helped refine the solution.
The result was a solution that is both powerful and easy to work with. It meets the needs of visitors and editors alike and demonstrates that short deadlines do not have to come at the expense of quality. The project showed that with trust, focus, and clear communication, it is possible to achieve excellent results in a short time.
We measure success not only in what we deliver but also in how our clients experience the journey. David, Head of Marketing at Zilenzio, put it this way:
The team at TwoFour, led by Richard and Josefin, has developed a fast and seamless website that works smoothly for both visitors and me as a content creator. A new collaboration that has been excellent from the very beginning. They truly see the bigger picture, opportunities, and solutions. So far, I have (for better or worse) not received a single ‘no’ throughout the entire project.
Acoustic damping simulator
A standout feature lets visitors audition how Zilenzio products change a room’s acoustics. Using calculations from Acoustic Facts, the simulator plays before/after audio so users can hear the impact of products like Dezibell Wall in environments such as a home office, dining room, or conference space. Visitors can also enter their own room dimensions to create a digital twin of their environment and test different configurations. Try the Absorption Calculator with a room of your own.
