Ultra-Lightweight Foam Glass Aggregates are produced from 99% post-consumer recycled glass. The aggregates have a highly frictional surface and combined with a low unit weight, inertness, high permeability, and insulating properties, foam glass aggregate is ideal as a lightweight fill.

These aggregates are 85-90% lighter than quarried aggregates, have a high friction angle, and are good insulators due to their closed cell structure. The manufacturing process converts glass cullet into an inert, non-leaching, rot-resistant, non-flammable and durable construction material.
