Not all yurts require insulation or lining, but they conserve heat and protect your yurt from the elements. Install your insulation on a day that is not very windy, and do this once the rafters are all in place. Use a step ladder to reach the top middle of your yurt, and spread the liner over the rafters. Have a friend pull the hemmed end around the rafter ends. Then, place the insulation on top of the liner. You can secure the upper area while your friend secures the perimeter.  To secure the lining and insulation, use a staple gun to add a staple every 4–8 in (10–20 cm). Once the insulation seam is aligned properly, use the foil tape to secure the seam. If you’d like, trim the insulation around the door frame so it does not get in the way. Remove the cover from the bag and get rid of the binding straps. The cover of your yurt is often in a bag made of the same material. Untie the straps around the cover. Then, place your step ladder inside your yurt so you can unroll the cover. To do this, bring the top of the covering through the center ring opening. Once the covering is through the opening, you can let the covering unroll until it reaches your door. As you stand on the step ladder, have a friend work around the perimeter. Once the covering is unrolled, unfold it 2-3 times to cover a bit in each direction. As you do this, look for the cut-out opening for the door in the top cover valance. The cut-out has many oval grommets, rather than round grommets.  Ensure the cut-out is centered over the door so you can easily install the rest of the covering. Work with your friend to unfold the rest of the covering across the top and perimeter of the yurt. Once the covering is halfway unfolded and covers half of your rafters, install a 2-5 twist-lock connectors or S-clips to secure the top cover at the door. Securing the cover near the door keeps the door detail aligned. Then, tie a cord to a few of the grommets on the top cover. Use the cord to help pull the rest of the fabric over the center ring and around the perimeter. Finally, pull the outside edge around so it is snug around the ends of the rafters.  It is imperative that the top cover is centered on the center ring and pulled down evenly. If not, your covering will be crooked. You do not need to fasten the cover to the center ring. Once the covering is in place, inspect the door frame to make sure everything fits properly. Then, use a marker to indicate the oval grommet locations. Drill 7⁄64 ft (0.033 m) pilot holes with the provided bits, and then fasten the twist-lock connectors.  If you don’t drill pilot holes, you may break the twist-lock shank. If you overtighten the twist-lock connectors, you can also break the shank. Once your roof is in place, consult your instructions regarding any specific finishing touches.
Install your roof insulation and liner facing if included in your kit. Take out the cover and place a step ladder in the middle of your yurt. Unroll the covering toward the door frame. Unfold your covering 2-3 times to begin wrapping the perimeter. Unfold half of the covering and secure it using connectors. Pull the top layer of the cover over the center ring and down the other side. Mark the oval grommet locations around the door to secure them.
