How To Insulate With A Radon Barrier
Floor:
- Do the same installation as underneath the concrete slab (see Radiant Heat in a Concrete Floor). Just make sure to seal it along the wall.
Exterior Wall:
- Install Prodex Under Concrete or Reflective-Bubble-White Poly, white side against the wall, with a multi purpose adhesive. Seal the seams with under concrete tape. Be sure to properly seal with caulking at the bottom and at ground level on the foundation wall.
