EPS and EPS-based insulation (such as Halo Subterra) is able to keep water away from a basement’s concrete wall. Of course, this doesn’t mean that other waterproofing methods shouldn’t be in place. But, this finding does mean that EPS insulation can perform both of its design functions — slowing heat transfer and groundwater management — very well.
Halo’s Interra rigid insulation excels at insulating walls, floors, and ceilings — it offers a stable, long-term R-Value, acts as a vapor barrier when needed, and reflects heat back inside if you leave an air gap.
