I own a landscaping business and work on equipment during the winters. I was thinking of an idea on how to insulate the ceilings and want some input. Get some thick clear plastic and staple it to the joist with cardboard strips. Then tack chicken wire over the plastic. Nail some furring strips every 24". Get in the attic and blow 6-8" insulation. So I'ts going like this. Plastic stapled to the ceilings with cardboard strips, chicken wire tacked or nailed to the joist, Furring strips nailed to the joist for added support.

What do you think? I plan to put metal later on the ceilings, but dont have that much to spend now.
