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.
Foam glass gravel (cellular glass) represents a simplification of sub-slab insulation installation for professional builders and DIY homeowners alike. In contrast with current methods requiring multiple products with complicated installation, cellular glass installation requires only a single product with minimal installation effort necessary.
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.
