Step 1. Using a serrated knife, cut to separate the Supply and Return plenums. Using the pre-marked line will give you a 30” Supply and an 18” Return. You can make your own marks and change the length to suit your particular installation. Step 2. Lay out the Supply plenum with foil backing side down. Fold along the V trench cuts to create a box shape. Align the backing-only lap joint as shown to create a box with rectangular shape. Step 3: Use foil tape to close up the plenum.
