Polyshield sheeting is a silver matt product that has a specific make up that will help with heat problems in the grow room. The metal infusion dissipates heat across its surface preventing hot spots from forming. Heat is kept inside the grow room, where you want it. This will assist you in keeping the environment under control and stop infrared escaping. The user can hang this sheeting in the same way as you would any other sheeting. Many growers use duct tape but if you can also staple it to the wall if damage is not an issue.
