Garage Door
1. Replace the rubber strip on the bottom of your door.
2. Add outside weatherstripping around the door.
3. Add inside weatherstripping glued to the top of the door and bottom of the door.
4. Tighten your door to the wall (loosen a few bolts and push it as close as possible.
5. Add that extra rubber strip on the ground.
6. Remove your overhead garage door opener and install a jack drive model.
7. Insulate the garage door itself with a corning product. I sealed all of the gaps in my door and filled in the holes with insulation. I used paint sticks to hold the corning product in on the sides.
8. Curtains help to hide the door and to create another insulation barrier. My curtains run on a track like on a hospital. They can be circled around the couch that folds into a bed. That also allows me to pull them around and open the door without having to remove them. (Each panel was about $10 at IKEA).
9. Use spray foam and rope caulk to fill in any gaps around the bottom sides of your door.
Foor
1. I epoxied mine. Paint or those foam squares are also cool.
Table:
I used a round wood riser to offset the lower side of the table.
Room:
1. Minisplit A/C. I run that thing all summer for about $.25 a day. I added an aftermarket smart thermostat/remote that will automatically run the thing to dry out the room. Plus, I can control it via my phone or my voice (via Alexa).
Lights:
1. I love my stadium lights.
