I had some trouble getting communications on confirmation of orders. One of the items ended up on back order and I didn't learn of it until I pressed with telephone and emails. The Owens Corning 703 took 2 months between order and delivery. I had to press Acoustimac multiple times to determine whether the boards were even ordered. generally poor communications from Acoustimac. Lastly, though not a fault of Acoustimac, the top two fiberglass sheets were damaged during shipping due to a fork lift jabbing into the product. Poorly packaged for a product susceptible to damage. In theend, I received the products I ordered, but it seemed to take quite a bit of prodding and inquiry from me to get the orders moving or at least learn of the delayed status. On a good note, the fabric I ordered was delivered promptly. Unfortunatly, I had to wait about 6 weeks for the other componemts to come in, which has delayed the overall project.
