Also, what did you use to secure and attach both items to one another (fan to Lexan, Lexan to roof)?
I purchased the Lexan and fan on eBay:
Cut the Lexan to size. Cut the 14" hole in the lexan and line the edge with butyl tape and then screw the fan to the lexan. Use the same process to secure the Lexan to the roof top. Then go over the edges of both the fan and Lexan with a sealant.
