I live in a relatively modern house with the typical prefab roof trusses. It has 4" fibre glass insulation, and I've boarded much of the area for storage. I'm looking at upgrading the amount of insulation but I can't just use thicker insulation without building up the trusses in some way. Is there an alternative insulation material that I could use to replace the glass fibre that is significantly better ? Thanks Tony
