What is the proper makeup of a foundation wall? I’m interested in achieving a high R-Value. I’m concerned with the proper placement of the waterproofing membrane (does it go on the Styrofoam or on the concrete)?
Is what I have below correct? For an R30 wall…
Underground (from outside to inside)
- 2″ Styrofoam (R10)
- waterproofing membrane
- 8″ Concrete Wall (R1)
- 2″ Styrofoam (R10)
- 2×4 wall construction (filled with pink insulation) (R12)
- Vapour Barrier
- 1/2″ Drywall
- Paint
Above Ground (from outside to inside)
- Parging material
- 2″ Styrofoam (R10)
- 8″ Concrete Wall (R1)
- 2″ Styrofoam (R10)
- 2×4 wall construction (filled with pink insulation) (R12)
- Vapour Barrier
- 1/2″ Drywall
