The future is bio-based.

Most acoustic tiles on the market are mineral based. Typically from stone, glass or gypsom. Now there is an alternative made from wood fibres - Aisti® Teno Tile.

Our Philosophy

The building industry and the materials used in maintaining and creating buildings are one of the main contributors to global emissions.

Using biogenic building materials - like wood - is an effective and proven way to reduce emissions from the build environment drastically.

Using bio-based materials often comes at a cost and with limitations due to strict building regulations designed around mineral based materials.

A paradigm shift is happening right now with leading architects and brave construction companies designing and building with bio-based materials as the obvious choice.

Beyond Rational was founded to support the transition towards a more sustainable building industry by presenting bio-based acoustic solutions — something we have coined conscious acoustics.

About us

Beyond Rational was founded on the belief that solutions that consciously support a transition towards a more sustainable future should be the obvious choice.


Most of the time this is not the case - especially in the building industry - where regulations and a certain conservatism towards new solutions have shaped the market.

Our team has years of experience designing and developing acoustic products and materials. This has provided us unique insights into the acoustic industry and positioned us to pick only the most ambitious and visionary partners to provide truly sustainable solutions.


We believe in a strong digital presence, not just from a product perspective but also from a customer perspective. We are UX driven, with focus on delivering a transparent and smooth user experience.
