Hi - I just purchased my 1st. townhouse. It's a condo. The basement has 3 exterior sides cemented. The 4th. side is shared with my neighbor; has big concrete blocks (yellow painted). The flooring's cement block. Furnace is in basement. The ceiling's having wooden joists. Has sump pump, townhouse not in flood-zone and there's no water problems.
I have not even done any home repairs but labor costs being so prohibitive - want to try insulating basement myself.
I was thinking of doing OvrX barricade system for the walls. As I understand, all I'll need is to drill holes in the cement walls, line up the panels and then screw them in tightly. The grooving system of the panels is then used to place the next panel and screwing that one in place, so on and so forth.
I am torn between doing OvrX vs. putting in stud walls, styrofoam, insullating batts, drywall,etc. Seems too much work and the drywalls are darn heavy! Cost wise is are stud walls+drywall cheaper? What's the caveats in using OvrX? For flooring, I intend to re-use about 800 sq. ft. of carpet leftover. Should I first Drylok the walls prior to insulating with OvrX? Finally, how to I finish off ofter OvrX? Can I just put primer and paint over the panels? Please help....

Are you looking for a "finished" habitable space? If so, you'll ultimately want studs and drywall walls. Even if you were ok with the ovrx it's not like you'll be running wiring or anything through those sheets, so you'd end up with studs over top anyway.

Studs filled with batts are cheap but they also are not a best practice based on everything I've read recently. The ovrx is good because it uses rigid insulation against the foundation, but I'd simply go with rigid glued on there and sealed up around the edges and forget the baricade for the walls. This approach will be ugly if left alone, which is why i asked what your end goal is. You can put studs in front of the rigid insulation and forget batts altogether if you like.
