Hey -- if it's still up there and working I think you're probably ok. You're beyond the warranty period for both products anyway, so if you had a problem you'd be on your own regardless.

The reality is that if you prevent moisture intrusion from occurring, both products will perform for almost an indefinite period of time.

 

Your EXACTLY right on this one. We were always firm believers in using plywood for subfloor due to the exposure of weather before getting the roof on...soon the plywood started to have voids in it and delaminate or even woodfiller in it to fill the voids....

On the last house we used a new product called avantech i think? Its 3/4 osb toungue and grove with a warrenty that it will not take on moisture. It was about 80lbs a sheet but it laid nice...the sheets arnt warped like plywood. The floor was rained on many times and the seems never came up anywhere in the house.

All i know is i carried every freakin sheet on that 1800 sq ft house and my the time i was done...my right arm was 3 inches longer

 

Yeah -- Advantec is one of those high performance products. Very dense, strong panels, but as you also found out -- heavy! When I was driving nails we called panels like that "arm stretchers" and for good reason!

 

Bingo, you nailed me.

Seriosly the only cons to my earth berm home are
1. Not all insurance companies will carry an earth berm
2. Not all banks and creditors will loan on one
3. Hard to get an accurate appraisel because once someone has one they ussually dont sell it so since they dont sell very often and they are suppose to compare your house to 5 equal homes that have sold with in 6 months with in so many miles.
4. Lack of windows/doors
5. Constant battle with moisture/humidity.

sounds cool man!

it's really a shame about numbers 1,2,3...

 

very cool--how do you like it?

 

this is what we use....they are changing their product to go with 16'' tall forms and have the solid plastic tab so you dont have to strip the outside out with metal strips for siding...

I like it overall. The house is really quiet and it seems to help with utility bills.
Negatives:
1) When the house was new and it cooled down at night, you could actually hear the styrofoam in the walls shifting in relation to the concrete. It was not very loud. I never noticed it during the day, only at night. It quit making noise after a couple of years.
2) It is difficult to hang anything heavy on the inside walls. Trying to set a concrete anchor through 2" of styrofoam is no fun!

At the Home Depots here in Atlanta the price for 7/16 osb is $4.96 a sheet. I'm using it for the ceiling in my garage.
