[Ferro List] Supertherm Insulation

[Christopher Glasspool]

Janoahsh,
What might be misleading is the term 19 RE (R value enhancement). I think this is thier own term, not a industry standard. I would feel better about the claims of this insulation if they described it as 90% UV reflective, and .05 R value or whatever per coating thickness. Some reflective foil claims give an R value, but that is deceptive as it only applies to heat transfer. What they don't say, and nobody does is that insulation is a manipulation that should be managed for the climate you live in. Taking into account things like the heating and cooling days per year, and the temperature swings between day and night. You might not want much thermal mass in a high desert climate - where the need is to cool quickly once the sun is up, and you may decide not to reflect the suns waves away in a house on the coast of Alaska. Also in Alaska would be the need to insulate walls, floors, and ceilings to the same level for best efficiency.
