Just to make sure I understand the insulation rigid board I should use on the floor

Dow 1/2" x 8' x 4' R-3.3 Polyisocyanurate Rigid Foam Insulated Sheathing is not the correct stuff right even...

any thoughts on painting the floor with the drylock or similar

Drick

I thought the same thing and if I remember correctly the answer was that you want the concrete the breath and the paint wont let the concrete breath

Im guessing laying down two layers of poly is not a good idea?

I am working on solving the water issues, sump pump, gutters draining into 4 inch pipes under ground and pipe running 100 feet away from house. Sealing cracks in floor, looking at drains around the...

is the 3/4 inch xps foam covered with 5/8 plywood strong enough to support a dryer and front load washer? They are non stackable and are side by side.

What are you trying to accomplish with the Delta? Just getting the floor off the concrete? Are you just going to tapcon the plywood to the concrete through the delta? I dont have alot of room, but...

Thanks Dana, I guess the thought of the dimpled plastic was for air movement to keep it dry if there was any moisture or seepage. So your recommendation is a 6ml poly vapor barrier, then the XPS...

Dane Thanks,

What are your thoughts on the use of a dimpled plastic membrane like the Delta FL or planton, then either 1/2 inch or 1 inch foam and then plywood on top of that. OR just the...

Hello

I am remodeling/refinishing my basement in Connecticut. I have a question about putting down a subfloor. What would be the recommended or preferred way?

(1) Put 1 inch XPS foam directly...

Thanks for the information. I guess Im better off venting the second bathroom on its own vent and go through the roof.

Now I have to figure out how to tell my wife to finish the bathroom I need...

Hello
I live in Connecticut and and am thinking about putting a basement bath room in during a remodel. I cant easily get to the upstairs vent stack.

My question is: I was told I could run the...

My question to them was about interior below grade. Ill copy the email they sent and post it here.

Today I got a email from Ownes Corning that stated they recommend that I do not use polystyrene in a below ground application, but did not specify why. I sent a reply back for more information, but...

In previous posts the advice I was given was to use Extruded Polystyrene Insulation in my basement walls.

I see at the big orange box store they have 3/4 -2x8 FOAMULAR Extruded Polystyrene...

Charlie, that is what I was thinking or just using 2 inch foam leaving the air space between the drywall and the foam. I guess the 2x4 really gives me about 3 1/2 inches so I would have to see how...

Can I leave the traditional 2x4 construction walls in place and put the rigid foam behind the 2x4 wall? I have to cut away the bottom plate as it is because its not pressure treated, so I will have...

Big Lou, I have no idea as I have not priced that option because I thought the fiberglass batts was the proper way. I see that I can use the furing strips with the rigid foam, but Im not sure how...

How about rigid panels can I make them fit to the existing framing or do I have to tear all that down and use the furring strips?

Also how do I attach the electrical boxes?

what kind of foam in place can you use with wood stud walls? I already have wood studded wall in place in my basement and have learned here that foam insulation would be better than the fiberglass...

Thanks for the information, I read alot of information and it looks like this may be the way to go. I have torn down sheetrock becasue it had mold behind. The
Mold fiberglass also had some mold...

I am no expert, but check to see if the mono flow t was installed correctly.

Mikey thanks for the reply, but from what I understand the sprayed-on polyurethane foam does not provide enough R value to keep the basement warm enough.

I am planning on adding heat and a...
