Step 9: Baffle installation
The baffle is a wooden structure that supports the fans and uses Reflectiix as the baffle material. The sunny side was spray painted flat black to absorb solar radiation. I built the baffle in two halves because it was easier to handle and then overlapped the Reflectix to create a continuous surface I attached a framework to the inside of the kiln to support the baffle.
I also cut holes in the solar collector behind the fans, to allow air recirculate.
It would have been much easier to construct the baffle prior to installing the greenhouse roof and prior to loading the kiln with wood. Don't make my mistake.
