Looks awesome, Jamie!! In regards to any bare wood near the smoker, such as the framing, enclosure hole, etc. you definitely want to cover any exposed wood with either the eclipse or reflectix. Here's why:
A number of years ago I lived in a brand new townhouse which had gas heat and hot water. The hot water heater was in a closet and sat on the bare subflooring. Instead of legs, the water heater had a plate that sat directly on the floor with air holes cut around it. Exactly a year later, my townhouse caught fire. I came home just in time to see a fireman shoveling my burnt, smoldering posessions out of my bedroom window. The fire marshal pinpointed the culprit as being that water heater. The plate base stored enough heat to slowly dry and heat the plywood until it reached its flashpoint. That complex had several fires over the next few years.
Not saying that your beautiful enclosure will catch but why take chances?
Wish I had your woodworking skills!! You could easily build and sell them!! Again a great job!
