The roof of a pole barn / post frame building is one of the largest components of the structure. Therefore, it can account for the most heat transfer in and out of the building. The easiest way to control the temperature and decrease heat transfer is to insulate the building. There is a variety of insulation available to control heat transfer such as fiberglass or foam, but these will not control condensation.
Reflective Bubble Insulation will not only create an R-Value and decrease heat transfer but it will also create a thermal barrier which will keep condensation from forming under the metal roof. This is especially important in cool climates when the building is being heated inside as this is a common culprit of condensation. Reflective Foil Insulation also works great in animal confinement buildings to help moderate temperatures inside the facility.
Use EcoFoil radiant heat insulation for the roof of new post frame buildings and existing pole barns, too
The roof of a pole barn can be insulated before or after the steel roofing is installed. The easiest way to install bubble insulation is before the metal roofing is installed. The builder can simply roll the insulation from top to bottom allowing it to drape slightly between the roof purlins. This will create a natural airspace allowing for the best performance. In existing buildings bubble insulation can be retrofitted by attaching it to the bottom chord of the trusses creating a thermal barrier between the attic area and the working space below.
IMPORTANT: Remember to allow air space when going over purlins. The air space between the metal and the radiant barrier is necessary for maximum effectiveness of blocking the transfer of radiant heat.
