Installing the Arched Cabin Subfloor | Video (WP Blog Archive August 2021)

What type of Subfloor are we installing for the Arched Cabin?

So for our Arched Cabin Subfloor, we chose to use Advantech 23/32 inch x 4 feet x 8 feet tongue and groove OSB subfloor. We paid a little bit more up front for this higher quality product, but it's a drop in the bucket compared to what that product is going for now! When we purchased the subfloor in October of 2020, prices had already increased dramatically, and we paid $43.61 for each 4x8' sheet. I just looked at the store we purchased it from, and it's out of stock, but if it were in stock it would be $110/sheet today!

Why did we choose Advantech flooring?

We wanted a really solid floor that wouldn't be all squeaky, and in all of our research this was the flooring that really shined, and was highly utilized by the professionals. It's OSB that is permeated with some sort of resin if I'm remembering correctly. It has a no sand guarantee (if you don't leave it out to the elements) and a limited lifetime warranty. I'm sure that we are going to be extremely happy with this product as time goes on.
