Radiant Barrier for the Attic

I'm off for the Thanksgiving holiday. It's much too wet outside to dig -- standing water in the trench I've been working on, so it was up in the attic to try to finish the area over the garage.

The Energy Audit had identified the area over the garage as having no insulation and no radiant barrier. I last worked on this September 20, and put down a layer of 6 inches of fiber glass insulation between the floor joists. This time I installed radiant barrier on the inside of the roof, and then put R-30 fiber glass rolls down on top of the previous insulation, running the new rolls perpendicular to the old insulation.




I put the radiant barrier up first and then filled in with the insulation. That should finish off the unfinished part of the attic, over the garage. I am left with the finished part over the garage, which needs a radiant barrier, and some other random places which also need radiant barrier. I needed to get more over the material. The radiant barrier comes in rolls of only 4 feet by 25 feet, so I needed another 4 rolls for these areas. These were about $184 at Home Depot.

I'll need a step ladder or something to install it over the finished floor part of the attic.




That should be tomorrow's work.
