3” Styrofoam Brand foam insulation helps to protect foundation walls when backfilling. The 3” STYROFOAM™ sheets will absorb the impact from rocks and clay during backfilling. They also create a secondary moisture barrier helping to protecting the basement from ground water and the R-15 insulation reduces the potential for cracking of the foundation due to freezing. By keeping the foundation warmer, the chances of condensation appearing on the interior is also greatly reduced.
