Often times, the weather and temperature outside your new pole barn is different from the weather and temperature inside. Hot days, cool nights are a great example. A closed post frame building will heat up during the day. Then as the sun sets and the weather begins to cool, the inside temperature can’t catch up fast enough and condensation forms on the inside roof and wall panels. Sometimes enough condensation to run and drip on the trusses, the floor and items stored inside.
Fortunately, there’s an easy way to curb the moisture building up. A combination of proper ventilation and a high quality insulation like Astro Armour usually does the trick. Just using one or the other may not be enough. Best results are achieved when both methods are used together. Single bubble or double bubble (bubble wrap) is not recommended.
Astro Armour is the least expensive method of insulating the underside of your pole barn roof to prevent moisture condensation on the underside of the roof panels. In the above illustration, Astro Armour insulation can be seen on the roof cutaway as well as the walls. At a minimum, we recommend Astro Armour insulation on the underside of the roof when the barn will be enclosed. In a building with 4 walls, you’ll find moisture on un-insulated walls at some point each year. It’s much more cost efficient to insulate when it’s built, than after.
Effective ventilation also helps reduce condensation. Ridge vents, cupolas, even gable vents at times. Roof ventilation such as ridge vents or cupolas allow warm out to escape at the peak of the roof, keeping your building just a little cooler. A more active method, but still passive, are gable vents that allow better air movement through the truss space and building, further reducing the build up of moisture.
