Attic Insulation

The big truck arrives.

Even in a compacted form, the insulation takes up quite a bit of space.

This insulation is available at Home Depot and is made from some recycled material.

Before I let them blow the insulation into the attic I spent a cranky weekend building this platform so I could move around the attic after the insulation was installed. The platform was required since the insulation would be R-30, or 8 inches deep. The ceiling joists (4.5 inches) plus the 2x4's (3.5 inches) I put on top with upside down joist hangers equal this height. Once the insulation is in place I can put plywood on top of my 2x4's. The foil cylinder in the middle provides me with access to my electrical boxes.

During the cranky weekend that I built the platforms I also filled large and small holes so that the blown in insulation would stay put. This photo shows the three materials I used to do this: from the left, bubble wrap within foil, fiberglass insulation, and foam in a can.
