It that wet laid cellulose? I haven't seen anyone around here that does it. Only seen it in magazines like Fine Homebuilding and Journal of Light Construction.

My understanding is that the tan stuff is closed cell insulation, and the gray is cellulose. I’m not for sure the exact term. They are using some sort of moisture to get them to stick though. After researching a bit, I think I’ll be somewhere around a 25 R factor.

Yeah the tan/yellow stuff is clearly closed cell foam. And it sounds like it is wet-laid cellulose on top of that from what you describe. I used a similar construction in my great room ceiling, but it was regular dense-pack cellulose that was blown in dry.

You can see the foam all completed and the netting has been stapled up on the near side for the cellulose.



And here it is all filled with cellulose

This method appears to be a bit more expensive. The biggest gain is controlling air exchange. By adding the cellulose he has a great R value.

Walls and ceiling done! R38 blown in the ceiling. Builder has an old electric furnace and a dehumidifier running right now. Warm enough to stand and drink a beer in. Def lots of moisture in the air from the cellulose though. Water running off the garage door windows. Starts on the interior sheeting next week he said!

By then things should be dried down enough. Just ride herd on the heat and dehumidifier. I think you need to be under 50%. But I'm no expert.

Glad it's moving along.

Just a little bit of moisture seeping out of the walls! It was 17 out this morning and the electric furnace that the builder put in was off at 65 when I checked it. I don’t think it’s going to take much to heat it at all!

Not much done on Monday, just a few sheets of plywood put up. Still holding at 65° and the furnace hasn’t been running the last two times I’ve been in there. Pretty good since it’s around 20° today.

Great looking shop thanks for sharing

All four walls got plywood today! Ready to see some tin on the upper part, hopefully tomorrow.

Looks great. Quick question...why plywood vs Osb? Is it a personal preference/finish or sizing issue?

Also, since you did closed cell insulation first, could you have put up like a typical r13 up on top of the closed cell and obtained the same result as you did with the wet/blown stuff?

Thanks!

The builder hates OSB. I'm not sure why, but he is 100% against it. He wanted to do metal walls, but I wanted a flat surface to build shelves, push a bench up against, things of that nature, so we compromised with the plywood. It will be painted when done, so I think it will look nice. We are then going to do white metal just like the ceiling the additional 6 ft up.

One of the main goals from the beginning when discussing our building with the builder was efficiency. If we had to spend a little extra on doors, windows, insulation to gain that efficiency then we wanted to do it. Our belief is that we are probably going to be where we are for the majority of our lives so we can get than money back over the long haul. I'm 43,a and my wife is 42, so we hopefully have a few years to gain all that back! I left it up to the builder to make some of those decisions for us, and this is what he chose to do. The same people that did the closed cell, did the cellulose at the same time, so I guess it was convenient for the builder, and probably just as economical as well.

I also think he ended up with a better insulated wall. Spray foam isn'tveven close to consistent in it's thickness. If he used batt fiberglas it would have compressed in some places and have an airgap in others. Using the cellulosecmethod he's ensured that his walls are uniformly full.

Hoist installers just called and said that they are coming to install tomorrow morning! I’ll post up some pics tomorrow eve.

 

[JHurt]

Got the tin up today!

 

[ovrszd]

Hopin he gets the floor heat goin while the weather is nice!!!
