Burlington entrepreneur Rob Conboy has high hopes for Glavel. The foam glass aggregate he held on a recent afternoon looked like a stone but weighed no more than a sponge.
Company CEO Rob Conboy said Glavel grew out of a Passive House conference he attended in Germany in 2016. He was scouting for European technology that could be used to lower the cost of energy-efficient construction in the U.S.
Building owners and developers in need of an alternative to petroleum-based sub-slab insulation and an overall boost to their sustainability characteristics, Glavel’s foam glass gravel is the solution.
Glavel’s manufacturing will transition to 100% renewable energy in summer 2020, dramatically slashing the embodied carbon emissions from the product.
Glavel gives new life to recycled glass, creating a valued use at a point when it traditionally becomes a valueless waste product. The circular economy is blossoming in the 21st century, and Glavel is at the forefront of it all.
