This is a very well done guide to sealing up air leaks in your home. Lots of good how-to pictures.
A couple small add-ons I would make:
- Replacing older can lights so that you can insulate right over them is a fairly easy DIY job -- it has the advantages of both reducing heat loss to the attic and getting some heat gain from the can light to the room.
- The method they give for determining if you have enough insulation is goofy. Instead, use the Insulation Upgrade Calculator or one of the online insulation guides to determine if your insulation is sufficient for your climate.
- For insulating over existing insulation, I like blown in cellulose. Its easy, insulates very well, is resistant to air currents flowing through it (see study below), and is easy on the planet.
