Inquiry (采购产品): fibramat I have a above the ground house with the AC/heating venting under the floor up through floor vent. there is no duct work, there is what I am going to call a bag (plastic that is lining the floor and up the wall about a 1/4 of the way up. What I like to do is build a box and duct it to the vents through out the house. Can I use the fibramat to make the box? How much is this material? **** Hidden Message ***** Arturo Armenta Jr 70001 Company: None E-mail: altec12002@yahoo.com **** Hidden Message ***** altec12002@yahoo.com
