Foam glass gravel is a unique building material that has recently gained popularity in the North American construction industry for under-slab thermal insulation. It’s produced by transforming post-consumer recycled glass into lightweight, closed cell aggregate that can be used in a variety of applications. Given the current challenges builders, engineers, and architects face in built environment construction, foam glass gravel is a future-facing solution poised to change how we think about subslab insulation.
Subslab Insulation is a core component of building construction that contributes to comfortable indoor temperatures while reducing energy consumption. Traditional insulation materials such as expanded polystyrene, cellulose, and mineral wool have been used for decades years to insulate concrete slabs, but foam glass gravel offers a more environmentally sustainable and efficient solution.
