KDM, I build alot of blinds for people.
Important. Keep a good overhang on the eaves and gable ends.
Once done, build a real smokey smudge fire with moist grass/ leaves inside. If smoke leaks out, bugs can get in!.
100% spray foam if you can swing the $.
1 froth pack, (350.00$) will easily do it.
Small woodstove. Won't condensate windows like propane.
If using plywood for sheathing, whip up a 5 gallon bucket of real MUD, like dirt! Muddy dirt.
Paint it on. Really.
Once it dries into the grain of the plywood, it's sets up HARD and repels water great. Plus it's such a natural color tone.
Windows, I build my own. I'll keep that secret to myself. (Grin).
But they swing in and sideways.
For sure, insulted the floor at least.
Use cheap carpet for floors and walls. Dark color.
So much more to add to this on how I do them but I'm on about beer #7 now and I'm loosing track. Lol.
Good to see you back.
