Wheel Well Boxes

I had been putting this little task off for quite a while, but finally got to it. The wheel wells needed to be covered, sealed, and insulated.

I started with a box made of two by two's and treated plywood.

All of the edges were caulked with silicone sealant.

The spaces were filled with 1.5 inch polyisocyanurate foam insulation and covered with double bubble reflective insulation.

Quarter inch lathing strips were added to give space for the double bubble insulation.

Finally, the whole thing was covered with another box of 1/2 inch plywood. This picture also, unfortunately, gives a nice shot of where I missed with the nail gun when nailing on the external sheathing. I nailed it again by hand...

Thanks very much to my father for helping with this. It went much more quickly with two people working on it than it would have if I had done it by myself!
