Although wood used indoors is protected from the weather, durability is still a major issue. Wood flooring, panels and furniture face wear and tear from daily use and must be designed to last for decades.
Indoor wood must appeal to multiple senses; touch, smell, and influence on acoustics, all contributing to the overall impression and comfort. The provision of high quality and aesthetics start in a modern and efficient factory process.
Continuous studies of indoor air quality (humidity, temperature etc) and the effect of different volatile organic compound (VOC) are needed to satisfy questions on public health.
To make products with circularity in mind, new indoor wood products need to be designed for improved reusability and repairability as well as for end-of-life disassembly when possible.
Fire safety relies on active systems and passive protection (charring, fire-retardant coatings). Modern mass timber and engineered wood products are designed to char, creating a protective layer that slows burning, often outperforming steel. However, certification and testing are expensive, and public financing would help speed up market uptake.
