Living In A House With Wooden Walls & No Sheetrock

It took me a while to figure this one out, because I’ve always lived in a house with standard Sheetrock walls, but a mystery came to light when I noticed something strange…more on that soon.

I have never been in a house will all wooden walls like in my tiny house. For the inside of my wall I opted for 1/4 inch Douglas fir tongue and groove siding. I’ve personally seen several tiny houses now that have used Sheetrock and it works beautifully, but I wanted the look of the fir. The fir was very easy to work with and the stuff is very light (only being 1/4 inch thick after all).

A few quick tips for working with 1/4 inch T&G interior siding:

  • Most commercial packs come pre-scored on the backs so you can snap them quickly with just your hands
  • Choose packs deeper in the pile and check for the grooves for damage
  • Use an oscillating saw (pictured above) to cut notches around openings such as windows, doors and outlets
  • Tung oil is a non toxic treatment for your interior

So now onto the mystery.

When I first hooked up my mini split, which does both my heating and cooling, I turned it on and cranked it up. Later that night I noticed as I climbed into bed and noticed that my sheets felt almost damp. I was perplexed by it and then started to worry that the dehumidifying part of the mini split wasn’t working. I checked the drain hose and a steady stream of water was coming out from it, so I knew it was working and not clogged. I decided I had just let a bunch of humid air into the house when I was going in and out and the mini split was just recovering.

Dealing with humidity when living with no sheetrock

Over the next week I kept finding the same thing and I began to worry that I was going to have a moisture problem. My sheets always seemed damp and I knew over time that could mean one thing: mold. I started thinking about how I could combat the problem, going over options in my mind for the better part of two weeks.

I was wondering if it was just so humid here in the South, was I in trouble? Was it that in such a small space, a human breathing put off too much moisture? These were the things swirling in my mind. Then I noticed something: my sheets were suddenly not damp any more. In fact they were perfectly dry.

This was very perplexing to me. Why was my house all of a sudden a very normal humidity, and suddenly the moisture in the air was so low?

I thought about this for a while, when all a sudden, it hit me!

It was the wooden walls! Unlike Sheetrock, Douglas fir has pores, which were used to transport water when it was a tree. Before I had installed my mini split, I left all my windows and door wide open to keep cooler, but with that came the moisture of humid NC summers and my walls drank it up.

Then I turned on the mini split and the dehumidifier started removing that moisture in the air. The wood naturally wants to equalize its open grains with the moisture in the air, so it released moisture back into the air. So essentially it took about 3 weeks for my house to breathe out all the moisture my wooden walls had taken in. My house breathes!

So the mystery is solved and my house is nice and dry. It’s interesting what you learn when you live tiny. In a larger home I’m not sure I would have noticed.
