Foamrox AS is a Norwegian industrial firm that has engineered a pioneering building material. We provide prefabricated solutions derived from Foam Glass—a material manufactured from recycled glass—specifically designed for demanding environments like tunnels and civil engineering projects. Our company prioritizes functional requirements, delivering comprehensive solutions for fire, water, and frost protection. These lightweight systems ensure rapid assembly, superior HSE standards, and long-term sustainability.
The idea behind Foamrox emerged from a desire to identify lighter, more practical alternatives to traditional materials like concrete within the tunnel and infrastructure sectors. These products utilize a core of expanded recycled glass (cellular glass).
In addition to gaining traction through various political and industry-led initiatives, the company’s solutions have drawn significant interest from contractors, consultants, and developers looking for climate-efficient alternatives to conventional concrete systems.
Throughout the 2020s, Foamrox has progressively expanded its deliveries to numerous Norwegian projects. To date, their technology has been implemented in over 100 tunnels, backed by solid references from most major contractors.


Sustainability is a core component of every evaluation we make during development and delivery. This involves careful material selection, assessing lifespan, and creating solutions that enhance operational efficiency on-site.
We recognize that our products are part of larger infrastructures, and true environmental impact is achieved through the project’s entirety. Therefore, we prioritize active collaboration with developers, advisors, and contractors to ensure practical and actionable eco-friendly choices.
Foamrox is committed to continuously refining our impact within the framework of current regulations and available technology.
At Foamrox, we are committed to delivering solutions we can take pride in. We emphasize quality, reliability, and open dialogue, striving for transparency in all our collaborations—both internally and with our clients. We believe excellence is achieved through partnership, professional curiosity, and responsible decision-making.
The experience, expertise, and dedication that guarantee superior solutions.
