How To Insulate A Quonset Hut
The equipment checklist includes:
- Reflective tape
- Super metal sealant
- A utility knife
- Perforated insulation pins
- Locking insulation washers
- 1/2" OR THICKER rigid foam board that you cut into 2" x 2" squares. (Retrofit application where insulation is attached directly to sheeting)
- Heat gun (for sealing seams of 10M).
Step 1 Use the Super Metal Sealant to add a nickel-sized glob onto the base of the perforated pins. Press the base of the perforated pins on to the purlin/girt. It's fine that the adhesive oozes through the holes of the base (you can smooth it out if you want). This part of the adhesive helps hold the anchor pin on to the metal. Space your pins 2 to 3 feet apart. Put some pins along the top of the wall girt because the Prodex is essentially hanging from the pins. Check to make sure the anchor pin is secure. The cure time can vary depending on the temperature and humidity
Step 2 Add The Spacers - While the pins are bonding to the metal, prep the foam board spacers. Cut 2" x 2" pieces from the board. These spacers are important. They provide an air gap which optimizes the performance of the insulation. Push the square foam pieces all the way down the pin.
Step 3 Attach your first row of Prodex. Push the insulation on to the pin. Leave the pin exposed because you'll push the next overlapping row of insulation over the same pin.
Tip: If needed, especially in for roof/ceiling applications, use one washer now to secure the first run of insulation and then another washer after you add the overlapping row of insulation to the pin. Remember to put pins along the top of the wall since the Prodex is essentially hanging from the pins.
Step 4 Line up your second run of the Prodex so that it overlaps the first run by a few inches. Once it's through the pin, push the washer onto the pin and press it down to secure the insulation. Now you can tape/seal your seam.
Step 5 Once the insulation is secured, snip the end of the pins. You may also want to apply tape over the cut tip of the pin to avoid someone getting cut.
