basement insulation
Subterranean thermal barrier
Basement insulation is material installed in basement walls, ceilings, or floors to reduce heat loss and moisture problems.
Because basements are partly or fully below ground, they present unique challenges—cold concrete walls, humidity, and potential water intrusion.
Common approaches include rigid foam boards against foundation walls or fiberglass batts between ceiling joists: We added basement insulation before finishing the space.
