The common pitfall that may seem to fall into is the fact that because the insulation board used in EIFS is derived from fossil fuels, it should be exempt from being specified. The truth of the matter is that EPS production accounts for only .002 percent of the world’s production of oil.
And it has been determined that one pound of EPS used as insulation will actually save 48 gallons of oil in a 50 year period of time. This significant in terms of preserving those resources.
Another little known fact about EPS is that it uses 30 percent less energy to make tan paper products. Think about that the next time you throw away your junk mail or run out to get the Sunday paper.
