    You can cut soft insulation with a utility knife. Foam insulation is typically sprayed into the wall, so you shouldn't need to cut that stuff at all.

    You want to make sure you have a tight building envelope when you're installing the insulation. When they leak air, it is known as not having a tight envelope. This is the number one contributor to problems related to heat transfer in the home.

    When working with fiberglass, put talcum powder or baby powder on your forearms and hands before interacting with the insulation. This will prevent the fiberglass from accessing your pores. Once you're done, get the powder off and you won’t be itchy at all.

    Simply insert the insulation sheets and fasten them. I recommend using a “hammer tacker” stapler for ease.
