Getting the walls straight

I have been worried that the drywall on the outside walls will eventually bend in toward the room because of the pressure of the cellulose stuffed behind it. The drywall will be screwed into 2x2 "nailers" at the bottom and 2x4 nailers every two feet up the wall as well as into the 4x6's every 8 feet along the wall. But at the top of the east-west-running walls there is a 2x10 that supports the roof trusses. It is nailed inside the 4x6 posts. This means the drywall will come up under, but not behind, the 2x10's.

As an aside, when I first realized the 2x10s were at the top of the east-west-running walls I worried I would have to build those walls inside them. Instead we decided to make them an architectural "feature" and leave them exposed along the entire length of the north and south walls, even in the bedroom and bathroom. I'll sand them down and "spackle" them to hide the seams and nails, just like drywall, so when molding is added and they are painted it will not be apparent they are wood.

Here's what a typical 8-foot wall section looks like, shown with one sheet of drywall attached.

 

Even though there will be a piece of trim under the 2x10 that will help keep the drywall vertical, I am concerned that the trim, only being nailed into the 2x10, will not be strong enough to resist the cellulose pressure against the drywall. I've decided to add a 1x4 behind the drywall and the 2x10 by screwing the drywall to the 1x4 before putting it up on the wall. I don't think it will be necessary to attach it to the 2x10 because the cellulose pressure against the billboard tarp sections should keep it tight. Here's a closer look.

 

Here's the view from inside the wall. Of course the exterior sheets, the cellulose and the billboard tarp sections are not shown.

 

Of course this means the 1x4 attached to the drywall will have to be tucked under the 2x10 first, then screwed to the nailers below. If this works it might actually make it easier to install the drywall. So far, without the 1x4, the first any only drywall sheet I've stood up has been difficult to hold firmly against the wall. I'll write about how it works soon. Tomorrow I've got to go find 64 feet of 1x4's.

Our first snowfall

It wasn't a lot of snow but it shows where one of our sledding runs will be. The area in front of the trees to the left has lots of birds in it most of the day. They eat seeds from the tall grasses and wildflowers. The view is from the large window where the kitchen table and benches will be.
