INSTALL GUIDES: Quonset Hut

The Most Popular item is 10M. The following are excellent 5M choices: Prodex 48 Inch, Fast Action, 62 Inch Fast Action, White, 72 Inch, 24 Inch and 16 Inch. Other options include: Reflective Bubble Reflective or Foil Fiberglass Vinyl.

How To Insulate A Quonset Hut

The equipment checklist includes:

Reflective tape
Super metal sealant
A utility knife
Perforated insulation pins with caps
Heat gun (for sealing seams of 10M).

Step 1 Put a glob of Super Metal Sealant on the base of the perforated pins. Press the base of the perforated pins on to the metal sheeting. 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 pins 1 per every 2 square ft. Allow 24 hour cure time. The cure time can vary depending on the temperature and humidity

Step 2 Push the insulation on to the pin. Once it's through the pin, push the cap onto the pin and press it down to secure the insulation.

Step 3 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.

A quonset hut requires a Radiant barrier, Vapor Barrier, and Insulation because of the unique nature of the metal arches. The sun's rays on the metal surface creates unbearable heat inside the building in the summer. Cold winter temperatures are exaggerated by the metal sheeting making it frigid inside. Warm temperature on a cool metal creates sweating (condensation). Prodex Total serves a true vapor barrier and condensation eliminator. It has a high R-value and it prevents radiant heat transfer (primary source of heat-flow).

Prodex Total is superior to fiberglass in quonset metal buildings because:

Its R-value is unaffected by humidity or water.
It doesn't mildew or promote fungus growth
It keeps the building cool in the summer
It doesn't promote nesting for rodents, bugs and birds.
It is much easier and less expensive to install.

Prodex Total is superior to double bubble insulation in quonset buildings because the heat from the metal skin doesn't cause its center to collapse. With a pressure of 6 PSI Prodex compresses just 6%. When the load is relieved it takes back its initial shape. The density of the foam is between 1.25 lb/ft (sq) - 1.87 lb/ft (sq). This gives the material real body.

Condensation: It can seem like a tropical rain forest inside an unprotected metal quonset. It's worse on those days where there is a greater contrast between temperatures at night vs. day. This typically occurs when relatively warm most air comes in contact with a relatively cold surface.

Using Prodex Total as your insulation will eliminate moisture (condensation) from forming on the metal sheeting. Prodex creates a shield (a new interior surface) that is warmer (or at least above the dew point). Prodex Total keeps the warm-moist air from reaching the cooler metal exterior.

Disadvantages of Spray Foam Insulation In Quonset Metal Buildings

High spray foam insulation cost
It doesn't prevent radiant heat transfer (the primary source of heat transfer into and out of a building - especially metal buildings and pole barns.
Do it yourself spray foam insulation can't be done by yourself to retrofit an existing building structure because of the chemicals and processes involved.
Nearly impossible to use in conjunction with another insulation type.
R-value will diminish slightly with age.
With the exception of cementite foams, spray foam insulation can release toxic fumes when it burns.
According to the U.S Environmental Protection Agency, there is insufficient data to accurately assess the potential for exposures to the toxic and environmentally harmful isocyanides which constitute 50% of the material.
Depending on usage, building codes and environment, most foams require protection with a thermal barrier such as drywall on the interior of the house.
Can shrink slightly while curing if not applied on a substrate heated to manufacture's recommended temperature.
Although CFC's are no longer used, many use HCFCs or HFCs as blowing agents. Both are potent greenhouse gases, and HCFCs have some ozone depletion potential.
Most, such as Polyurethane and Isocyanine insulation, contain hazardous chemicals such as benzene and toluene. These are a potential hazard and environmental concern during ray material production, transport, manufacture and installation.
Many spray foam insulations are made from petrochemicals and may be a concern for those seeking to reduce the use of fossil fuels and oil.
Most spray foams require protection from sunlight and solvents
