In the pursuit of a sustainable future, innovation is key. Researchers at VUB's Electronics & Informatics (ETRO) group have been working on the InToWall project for years. The result is a revolutionary new tool for the construction and inspection industry, called Transient Radar Method (TRM).
This technology offers a non-invasive way to get a clear picture of what's hidden inside our buildings, promising to transform how we approach energy efficiency and building renovation.
Unlocking the secrets behind the walls
The breakthrough of TRM is its ability to accurately measure the density of glass wool in a building's cavity walls. This precise, non-invasive assessment is a huge leap forward, helping to improve insulation evaluations and accelerate our journey toward carbon neutrality. But the real story of this technology is its versatility. The researchers have discovered that TRM can do much more than just check insulation. Recent tests have shown its capability to:
- Identify reinforcement types inside concrete pillars, providing crucial insights for structural integrity.
- Determine both superficial and deep moisture levels in walls, allowing for a precise root cause analysis of moisture issues.
- Conduct year-round thermal assessments, a major advantage over traditional thermal infrared imaging, which is only effective in winter.
- Monitor real-time carbon uptake in building materials, paving the way for more sustainable construction practices.
This wide range of applications, coupled with its ability to work in any season, makes TRM a powerful and unique tool for the industry.
A call for collaboration: Join the Klimaatparlement
This technology is ready to move from the lab into the real world. To achieve this, the InToWall team is actively seeking partners to collaborate in this pioneering venture of innovation.
Professor Johan Stiens will be pitching the InToWall project at the Klimaatparlement in Limburg on 19 September 2025. This event is a unique opportunity for businesses, investors, and stakeholders to see a live pitch, learn more about the technology's potential, and discuss how a partnership could help shape the future of sustainable construction.
By joining forces, we can refine this pioneering technology and accelerate the transition to a more sustainable and efficient built environment.
