I am a teacher in mathematics. I teach in primary, secondary and literacy. I use latex for writing exercises and tools for my students. My recent achievements in Latex are a small booklet of 16 pages (octavo letterpage) built using pdfPage as well as flash cards. I regularly use pgf/tikz. I am not yet fluent in English and Latex but I'm working on it! Currently I am working on a series of short lessons in mathematics, in Latex of course! My mother tongue is french.

comment Are curtains effective for keeping the room warm?
Curtains can (I think) increase the convection if they are not going from floor to ceiling.

comment How can I reduce the noise from a bathroom fan?
I think an inline fan is what is best to reduce noise. I use an inline for about 5 years and is barely audible. My main preoccupation was about the danger of frost in fan, but everything is going well despite the low temperatures: sometimes -30 degrees Celsius.

bcworkz : it's a good idea to put a ledger board. Do you know how to fix the ledger board? bolt, lag (?) or nail? I have to read about the shear reduction factor. Do you have link about it?

No, the floor do not have X-bracing. Currently the joist lenght is 13 feet. Joists have 3 supports (beams), approximately every 4'4 ". I want to free up space in my crawlspace, increase the load capacity and the rigidity.
