One of the easiest and most effective ways to save energy in your home is to add insulation to your attic.
Some clues that your attic needs more insulation: some of the rooms in your home are drafty; their walls feel hot or cold to the touch; you feel cold in some rooms or warm in others.
Even if your home had plenty of attic insulation when it was built, it might need some more now. Insulation can detach from the surfaces it’s meant to cover, which means it’s not able to do its job anymore. And some homes never had enough to begin with.
If your attic has a low ceiling, it might be hard to move around in, so a professional can probably do the job better and easier than you can. But if it’s roomy and you’re the do-it-yourself type, adding attic insulation can be a fairly quick and simple job.
