Dear ThermoClimb Customer,
Thank you for your purchase. I'm sorry that instructions were not included (all installation manuals are available on the RemingtonSolar.com website), however, the installation should be extremely simple as you secure it to your attic frame. The zipper has been tested and should hold up. If there are any defects or problems with your ThermoClimb, please contact Remington Solar we'll be glad to make you happy. By the way, upgraded zippers HAVE been added to new ThermoClimbs.These message and review boards are a great place for customers to vent (hey, we buy stuff too and want it to be right), but our own internal surveys with our customers show the insulation properties and performance of ThermoClimb is fantastic. So please let us know how it works for you this winter. Thank you again...Remington Solar
