Thanks for the reply, Paul. That was quite an undertaking for you and Sue.

As far as styrofoam inserts go, they are all in my cellar within their boxes. The only thing I have stored in my attic are the styrofoam peanuts. With two louvres and a vented rib running along the roof line, I doubt it would ever get hot enough to melt the peanuts. I would never put an actual HL in my attic though.

I'm sure the attic temperatures on a hot summer's day may reach well over one-hundred degrees, I doubt that it would ever reach a temperature to cause the styrofoam to ignite. My guess the flash point of styrofoam would be in excess of two-hundred degrees. Can any engineers or chemists give us an opinion of this subject?
