Does EPS ‘off gas’?

EPS does not off-gas. Fox Blocks forms do not and never have contained any CFC or HCFC products. The forms are made by a steam process that utilizes ‘pentene gas’ as a blowing agent. The blowing agent dissipates from the product within 48 hours of manufacturing. Fox Blocks forms are odorless, do not deteriorate, and do not off gas.
