Why you need to insulate and air seal

You are paying entirely too much on heating bills. You have read all of the advice and know that you should undertake whole-house wall insulation, but it seems like too much work. Guess what? It probably is. Wall insulation is valuable and necessary, but it is also a huge job when done after wallboard has been installed. There are two ways to do this, from the inside or the outside. On the inside, you can pull out walls in order to install roll insulation. On the outside, you can create holes in the siding to inject loose insulation.

Both methods are expensive and invasive. As an intermediate measure, install attic insulation throughout the house.  

Why Attic Insulation Works So Well

When whole-house insulation isn't in the cards, installing attic insulation can still work wonders because:

• ​You can do it yourself. While not an easy or fun project, you can insulate your attic by yourself. The worst part is getting the fiberglass batts up into the attic. Once the batts are up there, it is a tedious task of laying the batts between ceiling joists. Wires, vents, and non-IC recessed lights complicate the task.

• Heat rises. By putting a secure, heat-impermeable "lid" on your living spaces, you slow the migration of heat through your ceiling and attic.
