There are a few ways to insulate the garage door. Some places install a "foil bubble wrap" type. I do not really recommend this type.

You can get 4x8 sheets of thermax type insulation and cut them and friction fit or liquid nail them in place. An inexpensive project.

A better looking option, but more costly is buying the insulation kit made by Clopay, the same maker as your door. You can buy these kits at Ro-Mac on Rolling Acres Rd. You can install it yourself or they will come out and install it. The side you see is a heavier white plastic that looks nice.

Vents are a more controversial issue. Some folks just by soffit vents and screw them on. Some feel this is unsightly, and would compromise the wind rating, etc of the door. I would feel better about opening the window a bit and securing it, or in windowless garages one could install a intake vent in the wall.

I have actually seen a few folks have small fins cut into the bottom section, which might look better than the soffit type vents.
