Inquiry (采购产品): Rug Underlayments I have a large area rug (about 10' by 18') with a non-pourous backing on a hardwood floor, and I am looking for an underlayment that allows for breathing (air circulation)under the rug. Are any of your underlayments designed for such air circulation? If not, can you direct me to any that are? Thank you. **** Hidden Message ***** ALAN WHITE 260 CLUB RIDGE DRIVE MARIETTA, GA 30068-4801 USA Company: NONE Phone: 770-971-8780 Fax: 770-579-6447 E-mail: confirmback@aol.com **** Hidden Message ***** confirmback@aol.com
