Caution should be taken not to staple too close to the base of the tabs as the staples may pull out during the sheeting process. This could result in undesired appearance and a poor vapor seal. 3.5 3.5 At the joined seam, pull the tabs upward and staple approximately every 8”. The initial staples should be placed ½” from the end of the tabs. 3.
STEP 4– — The1. proper process ROOF STEP Perforating the vapor barrier 4.1 Roof insulation should be installed in one piece from eave strut to eave strut. 4.2 Roofs may require more than one roll to span the roof. The first roll should be installed across the ridge to the top purlin on the opposite slope. A splice will need to be made when installing the rolls for the opposite slope. Refer to 6.1 Roof Splice at the end of these instructions. 4.1 Ea ve 4.2 Ea ve g fin oo R n io ct re di 4.
STEP 5– — Installing insulation ROOF STEP 1. Perforating the vapor barrier 5.1 Use double sided tape to attach the insulation roll to the eave strut allowing at least six inches of overhang. C clamps may need to be used to temporarily maintain this connection until roof sheets are in place. 5.2 Unroll insulation to the other eave of the building allowing similar overhang. Keeping tension on the insulation. Double sided tape 5.1 Ea ve 5.
