Building question..

I showed my coworker how to change out his toilet a few weeks ago and his home is 7 years old and I was astonished he had particle board underneath his linoleum.

I doubt it was particle board. Probably that coated plywood like the LP Smart Board stuff they use for shed/garage floors.

This is a question that if you ask 10 contractors you will get 11 answers.

I GCed my last two house builds and really didn't save tons of money (like you can) because I over-engineered quite a bit of both builds. I used my time and my labor to build a "better" house.

My final decision after too much research was 19/32" GP Dryguard OSB for the roof, 19/32" Blue Ribbon T&G OSB for the walls and 1 1/8" PlyTanium Sturd-I-Floor T&G for the subfloor. All were on 16" centers. The floor is like walking on a slab.

It really isn't as much about OSB or plywood, they each have positives and negatives, but the actual product you use. Not all plywood and OSB are created equal. Let the contractor choose the product, especially the ones that build for low cost per square, and they are not likely to use the best products on the market.
