Phenolic foam insulation

This article needs more work. To help develop this article, click 'Edit this article' above.


Phenolic foam is considered one of the best material for thermal insulation.

The most common blowing agent used in phenolic foam insulation is ‘Pentane’. This is used to comply with EC regulation, because it is CFC and HCFC free, has no ozone depletion potential and low global warming potential. Pentane is a hydrocarbon. In order to prevent the blowing agent escaping and being replaced by air, the insulation boards are covered with gas tight aluminium foil or glass tissue.
