Foamed glass aggregate is a high performance insulating aggregate made for the construction industry. It replaces foam-based insulation, crushed stone, and lightweight fill in a variety of applications, delivering drainage, insulation, and compressive strength in one material. Foamed glass aggregate is easy to install and non-toxic, providing projects with durability and stability.
Foamed glass aggregate delivers measurable performance beyond what traditional fill and insulation materials offer. It combines the structural performance of crushed stone and the insulation values of foam insulation, making it a comprehensive solution for many engineering and environmental challenges.
Foamed glass aggregate is closed-cell, so it doesn’t absorb water, compress under load, or degrade over time. Unlike composite or foam-based materials that break down or lose carrying capacity over time, foamed glass aggregate maintains its structural and thermal properties, ensuring long term performance.
90% lighter than crushed stone allows for easy mobility on project sites and use as fill on compressible soils.
R1.7 per inch with no thermal drift eliminates the need for foam insulation in foundations while preventing thermal bridges and ensuring continuous insulation.
Up to 125 psi supports structural loads with minimal settlement and reduces the need for additional engineered structural support.
Closed-cell structure resists rot, mold, mildew, and pests, ideal for below-grade applications where moisture uptake is a concern.
Provides slope stability while reducing lateral movement and reliance on geosynthetic reinforcement.
Will not ignite or propagate fires.
Foamed glass aggregate is made from recycled glass with renewable energy. The result is a low embodied carbon building material that cuts carbon emissions without sacrificing performance or adding a green premium.
Diverts recycled glass from waste streams to create a high performance building material.
Produced in an electrified kiln with renewable energy, minimizing carbon emissions.
Free from VOCs, microplastics, and harmful additives.
Glavel’s foamed glass aggregate is manufactured to meet diverse engineering and design standards required by today’s construction industry.
