Installing Foil Bubblewrap Insulation On A Metal Roof

Foil bubblewrap insulation is ideal for metal roofs, since (along with your heating and cooling system) it will help keep your building cool in the summer and warm in the winter. Made of a single layer or double layer of foil wrap, this materiel does not let dust, wind or moisture get into your structure via your roof. This type of insulation is attached to your metal roof's rafters, which helps to ensure that it cannot slip out of place.

What You Will Need

  • Foil Adhesive Tape (Double-Sided)

  • Furring Strips

  • 2 Inch Screws

  • Electric Drill with Drillbits

  • Foil Tape

  • Ladder

Step 1. If you have a fairly high roof, you will need to position a ladder so that you can safely reach it. Make sure that the ladder is on a firm and even surface and that you have someone at the bottom to hand things up to you when you need them.

Step 2. You need to determine just how much insulation your roof is going to need, so start by carefully measuring it. Keep in mind that you should purchase a bit more (usually 10% more) than your measurements indicate, since you have to take in account overlapping and the need to provide a gap between the purlins. Purlins are the structural members between the rafters in your roof that help support your roof panels.

Step 3. Next, cover the purlins using double-sided foil tape. Then start unrolling the insulation, attaching it to the first purlin. Keep unrolling the foil insulation and attaching it to the purlins as you go. It's important that you let the insulation sag down a little between the horizontal roof members. This creates an air gap that improves the efficiency of the insulation.

Step 4. As you continue attaching the insulation to your metal roof's purlins, make sure that you overlap the sheets by about 2 inches. This is to help you temporarily keep the foil bubble wrap insulation in position until you can secure it in the next step.

Step 5. Use furring strips to secure the insulation to your roof's framing members. With a hand drill, screw the furring strips into place using 2-inch metal screws. While you're doing this, make sure that you don't accidentally remove the sagging that you allowed in step two.

Step 6. In order to prevent air leaks, you should cover all seams in your new insulation with strips of foil tape.
