« Part 4: Moving In Part 5 of The Journey of my Shed Shop series Part 6: Window height »

Well this isn’t going to work.

High outside: 93
High inside shed: 118 !!!!!
And that was with the window open all day

Shed has a ridge vent, but no insulation. UPDATE-9/15/2021: Found out after posting that the crew that built the shed failed to install the ridge vent. Crew coming back out to install the ridge vent.

There is foam board, radiant barrier, spray foam, and fiberglass. No clue what to get yet because I want it cheap and I want it easy, probably can’t get both. Above all though I want it to work.

I’m concerned with moisture in the walls if not installed properly. Houston is pretty darn humid. If I put in a membrane, there are no weep holes around the base walls, so no way for collected moisture to get out. Kinda stuck on what to do honestly.

To any of you kind enough to provide input it would be greatly appreciated. Otherwise I will continue my research online, or break down and call a pro.

I’m in Montgomery to your north. Insulation alone won’t do anything and unless you are able to commit to conditioning the air full time the moisture will indeed make your life miserable. I used perforated radiant barrier foil and put in a window unit in my shed. It cools down quickly and I can keep it cool for multiple days when I have active projects that I don’t want getting too hot or humid. In the winter a garage style heater fan will get it comfortable quickly as well.

Howdy Ho neighbor! I’m actually in Montgomery County, in Conroe. It’s easier to say Houston because sometimes in a group big group like this.

Did you notice any improvement in the actual temperature by installing the radiant barrier?

I’m currently leaning towards fiberglass insulation. I priced out some R15. Can do all the walls for about $220+tax. Possibly doing a radiant barrier layer first before installing the fiberglass. Will need to do the roof too.

I have definitely thought of committing to AC, but probably won’t cool it all the time. My only hesitation would be the potential for condensation without a proper vapor barrier. From what I have read, the vapor barrier should be installed between the siding and the studs, but the siding is already on and I really don’t want to take all the siding off. Was thinking that with insulation and no AC that there is no need for vapor barrier.

Another I’m pondering is if the limited use of the AC would eliminate the need for a vapor barrier. If it ran all the time there would be no question that it’s needed.

My shed has steel siding and before the radiant barrier you could just feel the heat radiating like an oven from the walls and ceilings when the sun was out. By establishing the barrier on the walls with an air gap on both sides, the radiant effect is eliminated allowing the air to cool off and cool everything inside. I keep the unit set at 74 and it can hold the 16×24 shed there except on the hottest days (still need to address the roof, but I’m planning to replacing the roof steel soon). I do make a point to turn it on the night before when I know I will be working there.

Here are some photos of the installation. I put the barrier on the studs and then used foam board strips to maintain a gap behind the pegboard paneling I used for the walls. I treated the space like an uninsulated attic, so there is venting at the eaves and roof ridge but I have not had any moisture issues for the last 2 years.

Thanks Kelly! Good idea on the spacers for the air gap! Appreciate the pictures.

I put a white roof on mine. It helped a lot. Plus it has white vinyl siding.

You replaced your old roof with a white one and noticed a difference, or got a white roof from the get go?

I washed off the light brown asphalt shingles and painted it using a roller with this. I did this over 5 years ago and it’s still working good. I may have to recoat next year because it seems to be getting dirty. I hope I can get away with hosing it off.

Watching this thread.
I’m in San Antonio and have resorted to doing seasonal work. My shop situation is very similar to yours and I built a covered section over my deck which is cooler but on 100 degree days its still hot as hell. Add PPE (I do my lathework on my deck) its even hotter…. respirator, faceshield, goggles, hat with large brim, apron etc.
Good luck!

So it turns out the crew that built the shed failed to install the ridge vent. They will be sending the crew back out to add it. Will update if it makes a difference.

I had my builder install two vents in my shed. One on the front and one at the rear. I also put fans in them. The one in the front vent blows air in and the one at the rear that blows air out. The fans are oriented to move air in the direction the wind blows. It helps a little.

What really cooled it down was adding the white Solar Flex to the roof and the white siding.
