This material provides outstanding thermal insulation properties, making it ideal for applications where maintaining temperature stability is critical. Foam glass aggregate acts as a natural insulator, protecting structures from extreme temperature fluctuations. It’s an effective solution for foundation and subgrade applications, reducing energy requirements for heating or cooling. In green roof installations, it insulates rooftop environments, helping to lower building energy consumption while creating more sustainable, eco-friendly spaces. Enviro-Rock measures R-1.7 per inch, so a 12” foundation layer is equivalent to R-20.

Foam Glass Aggregate is naturally fire-resistant, making it an excellent choice for applications where fire safety is a priority. Composed mainly of glass, it does not burn, emit smoke, or release toxic fumes when exposed to high temperatures. This fireproof quality makes it especially suitable for use in building foundations, embankments, and landscaping applications near structures where enhanced fire safety is desired. Non-combustible and fire-resistant.

Thanks to its porous structure, Foam Glass Aggregate has excellent sound-deadening properties, making it ideal for noise reduction in urban construction projects or in areas where sound insulation is essential. It can be used in road and rail embankments, helping to reduce traffic noise, or in building foundations to improve acoustic insulation. This benefit contributes to a quieter and more comfortable environment. Absorbs sound, reducing noise transmission.

Made entirely from recycled post-consumer glass, Cellular Foam Glass Aggregate supports sustainability by repurposing waste glass that would otherwise occupy landfills. Its manufacturing process emits significantly less carbon compared to traditional materials, and because it’s inert, it poses no risk of leaching harmful chemicals into the environment. By using this product, builders contribute to a circular economy and help reduce environmental impact, appealing to environmentally-conscious projects and green building standards.

Foam glass aggregate’s cellular structure allows water to drain freely through the material, making it ideal for use in foundations, backfills, and other structural applications where moisture control is essential. This free-draining capability prevents the accumulation of water, reducing frost heaving in cold climates and providing durability in freeze-thaw cycles. As a result, it offers long-lasting stability, making it a preferred choice in regions prone to severe weather changes.

Inert and resistant to aggressive substances, insects and rodents.

Foam Glass Aggregate is highly durable, withstanding extreme weather conditions and resisting degradation over time. It remains stable and effective even in challenging conditions, such as freeze-thaw cycles and areas prone to moisture exposure. Unlike organic or polymer-based materials, foam glass will not degrade, shrink, or lose its properties, ensuring long-term performance and minimizing replacement or repair needs. Long-lasting, resistant to environmental degradation.

Foam Glass Aggregate can help divert radon gas, a harmful radioactive gas that can accumulate in buildings from the ground. Due to its cellular structure and ability to create air pathways, it can be used as a radon mitigation layer in foundations, helping redirect the gas and prevent it from entering buildings. This application is especially beneficial in residential and commercial construction projects where radon mitigation is required by building codes. Applicable in concrete, backfill, insulation, and more.
