1. The attic is going to be trussed 24 o.c. I noticed that over time and with gravity the insulation batts would break down to a pancake. Giving the no longer intended insulation value. Is there a way (technique that could be used), or is there a brand that can keep up it’s fluffy state?
2. Sun room is going to be a 4″ slab with radiant tubing to heat the room. What is a good type of insulation for this under the slab, which is known not to give homes to bugs thus reducing the insulation value.
3. Same for my pool. Going to heat it! Might as well stop the ground from being a heat sink. I want to frame it with steal and use gunite. What would be a good choice here for insulation?
