How to insulate your Grease Monkey garage

This was one of the hardest and coldest winters that we have had in South Dakota for a long time. The new addition to my home is the part that connects to the garage and is very useful as a laundry room. However, with -30° weather, the cpvc pipes froze and then burst. (I will do a plumbing post on that little ditty)

There was just no way to keep that garage warm without insulation and walls installed. And no way to keep heat in while working on cars in those elements. So, lets begin!

Start by measuring your space. Length by width is just right. I also measured the space between the studs. Since they were 15" for most of them and the height of my garage up to the rafters was 8'. It wasn't terribly hard to figure out how many rolls of insulation that were needed. I counted the spaces between the rafters and multiplied times 8 to get the feet. The rolls came in 50 foot length so then I divided the total length by 50 to get the number of rolls that I would need. Feel free to add one more roll to your list.

I needed one piece of drywall for the area that needes patching and the remaining walls needed OSB. OSB came in 4X8 sheets. That's 2 rows on my walls. The rest is easy to figure out. I do recommend getting one more sheet than what you calculate...just to be sure. The OSB and the Insulation and the one piece of drywall cost me in total $200. The pneumatic stapler cost around $78. So, this project was highly affordable for me.

You will need:
Circular Saw
Jig Saw
Air Compressor
Pneumatic Stapler and Staples
Table
Extension cord
Chalk line
Tape measure
Marker or Pencil
Long trigger clamp

Utility scissors

Drill and bits

Gloves, dust mask, safety glasses (the usual)

Start by unraveling your insulation roll. I kept the vast majority of the roll at the base of the wall I was doing. I only unraveled enough to get to the top of the wall. I used a squeegee to get the extra reach to push in the insulation between the studs. You can use whatever works for you.

Once I got to the bottom of the wall I tucked the insulation in and pushed towards the back of the wall to  get a seam. If this is the technique that you use, do not cut right on that seam. You will need another inch or two of insulation. It takes a bit of practice, but you'll get the hang of it really quickly. For the vacancies between the studs that aren't the width of your insulation, I suggest rolling the insulation up and folding it to the side so that you have an idea of where to cut using your utility scissors. That was the easiest for me. Insulation is very forgiving. You can always add more so long as you don't add way too much. Go around the rest of the room in the same fashion.

I found it easier to install the bottom row of OSB first. Initially I had started with regular screws and a drill. But that was way too time consuming. Since I do have an air compressor the only thing I needed was either a nail gun or a Pneumatic stapler. I opted for the stapler since many of the nail guns that I saw in my price range we're Brad nailers. Brad nailers will in no way hold up your OSB. I bought all of my tools and supplies at Menards. I was able to save $100 compared to Lowe's.

I added my full pieces first to each wall. When installing the bottom layer of OSB make sure that you install the bottom portion to the lower stud first. I basically just made sure that the base of my OSB was lined up with the base of the floor and kicked it into place and then stapled it in. Since my OSB was 8 ft long, this part went by really fast. And no, I didn't clean out my garage...I just pulled things forward since it's the middle of the winter. That wasn't the most conducive to less annoying...just sayin'.

Next, you want to measure from the last piece of OSB all the way to the final stud in your wall. Use your tape measure to go across the length of the sheet and Mark the top of the sheet and the bottom of the sheet. If you are not used to using a chalk line, Mark the center as well just to verify that your measurements are correct. Lay your chalk line at the top mark and pull straight down to the bottom mark and hold tightly while you snap your line. Perfect straight edge! Later, I did this to the top portion of the wall as well so that I could find the studs when I need them for hanging things.

Use your circular saw to cut that line. Remember to keep your saw on one side or the other of the chalk line. Particularly if you have to go around to the other side to finish the cut. Position your bored and hammer it into the tight spots. Trim any areas that you may need to. Staple it in. Go around the room and do the rest of it in the same fashion.

If you have any electrical outlets, you will need to cut out a piece in your sheet for that. Since I am not a professional Carpenter, I was okay with small errors. I basically measured from the last piece of sheeting hung to the outlet, measured up from the floor, and measured the height and width of the outlet and marked my OSB. I drilled holes in the corners of my measurements and used my jigsaw to cut out the piece. Before talking down your board make sure it fits around your outlet.

Now for the somewhat challenging part! I am a whopping buck 15 soaking wet. My son was unavailable for the first day of me working on my garage. I had made a lot of progress in that first day so I wanted to keep going with the stamina. What I did was pull a table up against the wall and position my cheating on top of it. I found a number of different things that I could continue to stack on top of that table to get it close to the right position. I've been placed one of my manual car jacks underneath so that I can manually turn the Jack and slowly get it into the right spot. Although this is pretty time-consuming and most men wouldn't have to do that exactly, it was highly functional.

That little black blob is my manual jack

The corner was easier to position by myself - no jack needed

In order to get the top portion of the OSB completely fastened I did have to use a trigger clamp but before I remembered that I had one, I used my trusty old jack again. Because my OSB was slightly warped and didn't lay 100% flat it was very challenging to use my body weight to push it completely flush with the wall. The Trigger clamp was handy as heck! Go down the rest of your wall in this same fashion. 

If you have Windows in your garage oh, you will have to cut out a vacancy for them. I did it in the exact same way as I did the outlets. I used my chalk line since my window took up a good portion of the OSB. I was surprised at how accurate it actually was.

Pretty proud of this guy's turn out!

If you have someone on hand, it is significantly quicker if they can at least help you position the sheets on the top half while you tack down the lower half and come back later to clamp. When my son helped the next day...literally an hour or more shaved off of my time. I had all of my boards pre-cut and ready though too. 

Once you have gone around the room in this fashion...pat yourself on the back! This is all I did in my garage and what a difference!  Although a friend of mine has a drywall lift and he also did the top rafters as heat does rise and escape that way. This is all I cared to do. Good job Grease Monkey...now you can design your garage any way that you see fit!!
