The US Department of Energy recommends at least R-2.5 exterior insulation for most of the country, which cannot be met by popular fanfold insulations. The TriWall siding system provides over 300% more r-value than hollow vinyl siding, and exceeds the US Department of Energy recommendaiton by up to 28% (depending on profile).
TriWall features a contoured foam insulation made of graphite polystyrene from BASF called Neopor. Neopor provides higher insulation value than competitive products made of traditional EPS insulation, providing greater energy efficiency in the same thickness of insulation.
