1. Climate Change 7. Nuclear Waste
2. Water Extraction 8. Waste Disposal
3. Mineral Resource Extraction 9. Fossil Fuel Depletion
4. Stratoshpheric Ozone Depletion10. Eutrophication
5. Human Toxicity11. Photochemical Ozone Creation
6. Ectoxicity to Freshwater and Land12. Acidification

Armacell has independently verified EPDs compliant with ISO 15804 and ISO 14025 for AF/Armaflex Class O, AF/Armaflex, Armaflex Ultima, HT/Armaflex and NH/Armaflex (see

Armaflex products have a GWP and ODP rating of zero. The gas given off in the manufacture of Armaflex is nitrogen, which makes up the majority of air. The GWP and ODP certificates are independently verified by Bureau Veritas, available on request.


Our Tubolit polyethylene foam insulation has a GWP of 3 and an ODP of zero. The blowing agent used is Isobutane, which has a negligible ODP and a GWP value only 3.3 times that of carbon dioxide.
