I have a contact who is a distributor of the product. Let me know if you want to get in touch with him. He is very knowledgeable. Tim |

P2000 is a reflective insulation made with EPS board material. It's under scrutiny right now for the R-values it published. If you look closely, the R-values they publish are nothing spectacular. In order to get much of any R-value out of this product at all, you need to have an air space in front of the foil facing to reflect the radiant heat. If you spray foam directly to it, you reduce the reflective "r-value" of the material greatly. It's also difficult to spray foam to it because the foam wants to slip off the shiny alum surface and not adhere well. |

Riversnrocks: So your saying that reflective insulation cannot reflect heat produced through conduction? I'm interested in reading some info on it if you have a source... |

Think about what the reflective surface is. It's aluminum. Aluminum is a great conductor of heat so how does it work well as an insulation if it's great at conduction. The principle is that the surface reflects the radiant heat away from teh material before it's absorbed. In order for radiant heat to be reflected, there needs to be an air space in front of it to allow it to reflect into. Otherwise you're back to conduction. On another note, you have to be cautious about what surface is in direct contact with the aluminum materials because some will eat the aluminum up within a couple of weeks. This is the issue with some of the products like Tek-Foil which put an aluminum surafced material under concrete floors. Without something to protect the foil, it's gone. Not to mention the condutcion issue if it is still there. Also consider galvanic corrosion where two dismiliar materials creat an electrical current which causes one of the materials to oxidize. |
