I ordered the ViperII vapor barrier on April 14, 2022 and received it one week later. Unfortunately, the roll of ViperII was poorly packaged and the packaging was heavily damaged. As a consequence multiple layers of the vapor barrier were perforated during the transport. Since we need the full roll for covering the area under our slab, we could not complete the slab preparation. A few days later I sent the pictures to Insulation4US. They responded quickly stating that they would contact the supplier. 4 weeks later (today is May 25, 2022), the issue is still not solved. I needed to cancel the concrete pour and cannot even schedule the concrete pour since I do not know when I will receive the replacement. This is extremely frustrating! I am revising my rating from 1 to 5 stars. The reason is that Insulation4US forwarded my complaints about the bad packaging and the ensuing damages to the producers. After quite a few emails the producers sent me a new roll of the vapor barrier through Insulation4US. And this time the packaging was much better. I very much appreciate the help by Fiona in the office. I am a happy costumer and will order again from Insulation4US.
