This non-toxic smoke stick generates a small amount of smoke to help you identify drafts in a home. Pull the trigger on the smoke stick near the area that you suspect a draft and see how the smoke moves to show the air movement. You can use this Smoke Pencil all over a home as you seal and insulate. Use it to see if your fireplace chimney will draft properly or test if your damper is sealing tightly. See if windows and doors are weather stripped well and seal tight. Test to see if you need to tape or mastic the HVAC ducts in a basement or attic....and there are many more uses!
