Insulating a garage door that doesn't have "channels"

[mdameron]

For lack of a better term, I'm calling them "channels". That is where, on most garage doors I've seen, you would pop your rectangular piece of insulation into. You'd basically not need any adhesive.

I'm having a house built and I don't have those channels. The door may actually be already insulated, though the builder said it wasn't. I've never seen anything like this door, but I'm not a door aficionado. Here are two pictures of what I'm talking about. What to do in this situation? I definitely want to insulate the door as I'm in Houston and the door will be W/SW facing.

Its a wayne dalton probably 9100 - its already got r8 urethane insulation.

And it's probably going to leak around the edges, anyway.

Insulation slows heat from *conducting* through something. A thin piece of aluminum foil will reflect all the radiant energy of the sun, if that's what you want. A white painted surface reflects a lot.
A space in a wall or door meant for insulation is usually called a cavity.

Thanks for the posts, guys.

I've got that same door. I stapled bubble wrap insulation to the inside of it. Not the greatest, but it helps to keep the sweating down in the winter when the heat is on.
If I had to do it again, I'd buy a door that's already insulated
