I’ve talked about attic ventilation issues before, in fact it’s probably one of the most popular posts on the blog to date. In that article I touch on this issue and in this video I decided to go a little more in depth based on the frequency this problem comes up in conversations.

    I’ve read your many posts, Why not put reflective insulation over the floor in the attic, rather than the attic ceiling? Wont that accomplish the same thing and be much easier??? I mean, the sunlight travelled a million miles, it doesn’t matter if we stop it on the roof joists or the house joists. In fact, one might make the arguement that it might be better. Flow and radiation follow Pouiselle’s law where the flow and radiation dissipate with 1/R the 4th power. So the reflective wave energy will dissipate much faster before it reflects back through the attic joists. This is also an arguement not to insulate your attic roof, but just the room right? So maybe put down a highly reflective floor in the attic and make sure it’s air tight?

      Scott, you can definitely lay the foil on top of the insulation. In fact this is the preferred method in cold an mixed climates. Here is the page on the Radiant Barrier On Top Of Insulation The main advantage of stapling up is when you have ductwork in the attic. There is a saying that “putting ductwork in the attic is like making ice cream in the oven”. So, stapling up will reduce heat both into the ductwork AND put the ductwork in a less hostile environment.
