If you are using sheetrock for the ceiling, then a well done blow in fiberglass insulation should work as well as standard fiberglass batts.

Get the truss company to build your scissor with a raised energy heel. That gives you the room for R38 all the way to the plate line including venting.

I'll be using Icenyne open cell foam insulation in my next house. The different foam insulation that are available are a fair more expensive than blown in insulation, but perform much much better.

Open cell will hold moisture.

We had to have fiberglass batts on our scissor trusses instead of blown in, inspector said blown in will slide/settle downhill over time and wouldn't allow it.

I live in the desert. 20% relative humidity on average. It performs well here.

How glad am I that we have great weather in RSA, I have scissor trusses, exposed with no ceiling nor any insulation, gets a bit got in the 40+ deg c, but then I put the fan on or open the tree doors.

I thought foam insulation had to be sprayed on and wasn't set up as a DIY option yet??? If someone's done this as a DIY please tell us where you got everything you needed. Thanks

I'd like to see some detail of that too...I have half a shop of scissor trusses that need insulating. The tip on truss design is a great one...just 6 years too late for me.

I have R38 batts with cardboard baffles at the plates, mine is very easy to keep warm and its a great place to hide in the summer as well....
