We have just had a house energy audit and they recomended an attic solar energy blanket. Cant post link as new member but searching for "solar attic blanket" finds it.

I understand it stops radiated heat not convection or conduction, but I would have thought most of the heat transfer in the attic would be convection or conduction and $2000 for the attic is a bit pricey for an unknown return.

Does anyone have any experience with these products?
