I recently insulated my entire house with foilfaced fiberglass batts, and I found a good tool for cutting the stuff down to size — hedge shears. That’s right, but they have to be sharp. They easily cut through R-19 foil or kraft-paper faced batts even when they’re fully lofted. You don’t have to compress the insulation to cut it, as you would if you used a utility knife.

Insulation Knife
If you like insulating with mineral wool, this knife makes cuts that are clean, neat, and easy — it's much better than a utility knife which can be slow and messy.
Foam Gun
We like using a professional foam-dispensing gun as opposed to straw cans because it allows you to easily control bead size and reuse the can.
Great Stuff Foam Cleaner
It’s important to clean and maintain a professional foam-dispensing gun, and this product fits the bill. It has a spray applicator for general cleaning, plus it screws onto the dispensing gun so you can clean the inside.
