Foamglas Cellular Glass Insulation
What is Foamglas Insulation ?
Foamglas Cellular Glass Insulation is an advanced, high-performance material made from millions of hermetically sealed glass cells. Its unique cell structure ensures unparalleled moisture resistance, thermal stability, and compressive strength, making it ideal for a wide range of applications including roofs, walls, floors, and foundations.
Protect your insulation from moisture damage—FOAMGLAS® prevents interstitial condensation 💦🔒
Fire won’t chase you, but smoke will. Don’t let toxic fumes trap you—insulate with FOAMGLAS® for ultimate fire safety! 🔥🚷
No deformation, no compromise—FOAMGLAS® ensures your insulation stays intact, no matter the load! 🏗️🛡️
FOAMGLAS®: The sustainable insulation solution that’s good for the planet and your building. 🌍🏢
Why Choose Foamglas Over Traditional Insulation?
Thermal Performance
Foamglas maintains thermal efficiency over time, even under extreme temperature gradients.
Moisture Resistance
Unlike polystyrene & mineral wool, Foamglas is impervious to liquids or vapor form, eliminating the risks of condensation & mold.
Non-Combustibility
Classified as Euro Class A1 (EN 13501), it does not burn, emit toxic fumes, or contribute to fire hazards.
Sustainability
Made with 60% recycled glass and 100% recyclable at the end of life, Foamglas supports LEED and Al Safat certifications.
Strength and Stability
With no deformation under load (EN826), it supports heavy structures like rooftop car parks without additional screeds.
Chemical Safety
Free from VOCs, flame retardants, and harmful chemicals, ensuring a healthy and safe environment.
Applications
Foamglas is versatile and suitable for:
Roofs :
Including green roofs, standing seam systems, and photovoltaic installations.
Façades :
Ideal for ventilated façades, preventing cold bridging and moisture ingress.
Below-Grade Structures :
Basements, foundations, and underground slabs where water resistance is critical.
Industrial Use :
Effective in oil and gas applications where condensation risks are high.
High-Load Areas :
Roof gardens, terraces, and driveways where compressive strength is essential.
How Foamglas Outperforms
Moisture Protection
Foamglas’ closed-cell structure prevents vapor drive, ensuring insulation remains unaffected over time.
Fire Safety
Demonstrated superior performance in fire tests (e.g., BS 8414, NFPA 285) compared to plastic-based insulation materials.
Sustainability Leadership
Foamglas production relies on renewable energy,including hydroelectric power & avoids environmentally harmful chemicals
Thermal Coefficient of Expansion
Long-term Warranty
Dimensional Stability
No creep or deformation under heavy loads, ensuring long-term performance without compromising waterproofing membranes.
