What kind of walls are those?!?

9/8/2015

It is amazing how fast the walls went up over the last ten days. Our thanks again to the guys doing such a great job!

Let me invite you to take a closer look inside.
I must admit, I am quite excited to have an "inside" to invite you into!

To the right is a good example of the exterior walls.
No, that isn't double vision, there really is a gap between two walls.
We have a 4 inch wall, with about a 3 and a half inch gap, and then another 4 inch wall.

This allows us about 11 inches of insulation. The majority of which will be recycled cellulose insulation.

Heat can also be transferred through the wood in the wall itself. While wood is not a very good conductor of heat, it does conduct some heat. As such, the more wood in your wall, that crosses from the inside edge of the wall to the outside edge of the wall, the more heat is lost.

This is the reason for the gap, without as many areas with a complete span of wood from inside edge to outside edge, the less heat, and therefore energy, loss.

Next up, the roof rafters!

Cellulose sinks/settles over time, like a bag of chips. It also holds moisture and can be a breeding site for mildew. Any response? I went with rigid, closed-cell foam. It isn't renewable, sure. Wish someone would invent a cellulose-based rigid foam product that can be sealed.

All good concerns!
The amount of settling depends upon the quality of the install.
One of the tactics we are taking is to have dividers, such that each section is narrow. The wider it is the easier it is for the material to sag.

The moisture issue needs to be carefully planned for. If moisture can get it, it must be able to easily pass through the insulation.

Their are pros and cons to every insulation choice. For us, the inherent energy and renewable aspects to the cellulosic material won out. Of course, there are areas where other types do a better job, so cellulosic is not the only insulation used.

I'll have lots of details in an upcoming blog when we start the insulation.
