Subfloor is ready to go in. I need a break though, those 3/4" 4'x8' OSB sheets are heavy. 14 of them from the driveway and around back through to the basement. Got my workout for today.
I chose to use the System Platon
product for my subfloor. I liked the concept of the Dricore, but I was not excited about having to do another subfloor on top of it, on account of Dricore not recommending you glue to their product. So, I did the next best thing and got the best of both worlds I think. Platon is basically the bottom of a Dricore panel, but it comes in a roll. The rolls come in different dimensions, but I chose the 8'x65' roll that I got for $173 incl tax from my local Certainteed distributor. Here it is:
Here's a closeup of the ridges. The dimples keep the floor off the cement ground, allowing for some circulation. It also allows for enough room to run speaker wire, which is my plan for the front 3 speakers. During the install, I am going to lay string where I want wires. After the floor is installed, and the wire is acquired, I will attach to the string and pull the wires through. Sounds like a good theory right? We shall see if it works.
The install instructions say to install this right up against the walls, and then to leave a gap between your wood subfloor and the walls. I chose to put the previously mentioned 3/4" T&G OSB panels on top of the Platon. It should provide a nice soft warm floor for the basement. Here are the 14 sheets in all their glory. I think I heard them talking about how they kicked my arse, but they shut up when I looked at them harshly.
Once you have the Platon laid out and the OSB on top, you then come back and secure the OSB to the cement floor, through the Platon, with these. They require a pilot hole drilled with a hammer drill, then you drill these down in the hole. This is going to be a real pain that I am not looking forward to. Especially working by myself.
Going to start the subfloor Thursday morning. We shall see how far I can get between Thursday and Friday morning for about 4 hours each.
