1. Cellular glass insulation
the alternative to mineral fibers and polystyrenes
Consultant queries how to choose the right material
• Sustainability / Ecology
• Humidity and fire risk
• Load bearing capacity
• Key study: New Doha International Airport
• Conclusion

2. Consultant :
Which thermal insulation material to choose?
λ
Thermal conductivity coefficient (λ)
Resistance to humidity
Behaviour in fire
Dimensional stability and load bearing
Long-term economy
Sustainability!

3. What is a sustainable product?
One broad definition of a 'sustainable product' is an item or
service that minimises its impact on the environment at each
phase of its life cycle.
production usage after use

12. Cellular glass is non combustible

13. Load bearing capacity
Single loads:
•Landscaping
•PV-panels
•Raised floors
•Special roof systems

14. NDIA, Qatar
•Less weight
•Less height
•Less time
>more efficient
>more sustainable

15. Key study 4: NDIA New Doha Intern. Airport
FOAMGLAS –
as thermal insulation with slope 50-280mm
as void former 180mm
Light
Rigid and not compressible
Fire safe

16. Cellular glass is waterproof
