floor insulation choices in pre-fab shed

12 X 32 prefabbed shed in Western Maine, Zone 5.  I believe.  Shed is a plywood subfloor on a joist system;  held off the ground by CMU’s to level it.  This will be a 3 season living space until we are able to build a home.   I am thinking about either 1″ blue board or 1″polyiso glued to the existing floor, and then add 1/2″ CDX over that, screwed to the existing sub floor.   Bottom plate junction with insulation and plywood will be airsealed.   Cost is an issue of course.  I know I will get a higher R value with…

I want to do things right, without going overboard. Doing everything myself). There are a…

High Humidity Despite Whole-House Dehumidifier

Hello. We completed building our home a couple of months ago. We decided late in the game to add and ERV onto each furnace. As a result, it was tied into the existing duct work (I know this isn’t ideal but we didn’t feel like ripping up the walls). On the system that services the second floor, we added a whole house dehumidifier. In the basement, we have two free standing large dehumidifiers. On very hot, humid days, the humidity upstairs is significantly higher than the first floor. Since we have the whole house dehumidifier upstairs, the humidity levels should…

Updating HVAC and Attic Insulation

I’ve just recently moved into a 1970’s house in Salem Oregon that could really use some significant HVAC and insulation upgrades…The roof is framed with 2×4 trusses and barely has blown in insulation to the top of the bottom chord, and none of the junction boxes for ceiling ligts are detailed well at all so let lots of air through. In addition the duct work in the attic is neither sealed or insulated. All this leads me to want to start with removing all the ductwork in the attic and replacing it with a mini split while I air seal…
