Q:  Our attic has fiberglass insulation with cellulose insulation blown over top. I would like to cover the blown insulation with a thin, breathable/perforated plastic to keep the dust down. Is there a product you could recommend?


A: I would recommend the landscape fabric that looks like screening but not the real cheap plastic kind with holes punched in it because it might restrict the air flow causing mildew to form. Also be very careful not to compress the insulation otherwise you will kill its insulating value.
