Hi there,

I'm getting ready to finish off my 6 year old basement. I have actually framed over the builders insulation wrap - tried not to crush the wrap too much.

My question is, would I really get more R value by cutting the plastic along the edges of the studs and putting another roll of r12 on top from top to finish (so essentially, the top half will have double). Otherwise, I was thinking to leave as is and just insulate the bottom half.

Any feedback would be appreciated.

Basically what we do on my sites are as follows.

First we remove the existing plastic and R5 pink the builder has installed.

We then install R10 roxul bluecore and we glue it to the foundation with the applicable adhesive materials.

Then we close and cover every open seem with Tuck tape. The Bluecore now is your first level of /r10 insulation and your vapor barrier. We then frame the outside walls and install Rouxle R20 insulation within the frame after running all of our electrical and water lines.

You now end up with a far more efficient vapor barrier, as well as R 30 insulation in your exterior walls.

Then we use DriCore 2'x2'

subfloor panels for the basement applications. This also warms the floors for your finished product as well as allows water intrusion to flow below and dry up. Or in the case of a large water escape, the water will run below the floors to the drains.

Hope this helps.
