Insulation Question

[blackfoot]

I am staring on the insulation of my 26'x52' shed. Here is my situation. I have what are called "room in the attic trusses" which created an upstairs storage room. I have already installed the flooring in the upstairs portion. Right now, I have complete access to the floor truss bays from down below but a portion of the access to the top of those truss bays are covered by the upstairs floor. I have some electrical boxes in those bays and some wiring which is mostly stapled against the bottom of the truss.

Question - with the the tops of those bays partially covered - approximately 12' of the 26' width of the shed, what type of insulation would work best? I am using batts of course on the sidewalls, but, should I go ahead and put in the ceiling and blow in insulation between the finished ceiling and the floor up above (7.5" final clearance) or should I put in batts now and then finish the ceiling later?

I ask this question for two reasons:

1). I am wondering if the 7.5" clearance (finished height of the truss bay or the distance between the finished ceiling and the finished floor above) offers enough room to blow in insulation effectively - there are some wires and electrical boxes which might hinder the flow of the insulation.

2). I absolutely hate working with batt insulation that isn't encapsulated and I have not been able find any encapsulated R19 batts for a 24" wide truss measurement.

Any advice would certainly be appreciated.........

I would post a photo of the shed but haven't figured out how to do that yet.

Which areas are you wanting to heat? If you want to heat both no insulation is necessary, but it would help with sound control. If it is going to be a living space fire rated sheet rock may be necessary.

The only area heated will be the lower level. The second story storage area will be cold.

For the best results batt under the floor sections and blow the sides after you install the celing.

Personally, if it were mine, I'd put batts in and do the ceiling later. I absolutely hate the blow in insulation. If I could, I'd **** out all of the blown-in that is in our house and put in batts. The blow in is dusty as hell if you have to get up in the attic for any reason. I was cleaning up dust for months when we re-blown more insulation in the attic a few years ago

I would do the batts and make sure I use 6mil vapor barrier before I put the ceiling up. You will have to move the wire to inside the trusses if they are stapled to the bottom surface of the truss.
I understand not wanting to mess with the batts, some members have found that hiring out for insulation is not that much more than DIY because they can get the materials cheaper. You might call around to get a quote and check it out.
