If you have high humidity, spray foam isn’t for you

Before installing any insulation, it helps to research extensively to know if such a move will yield positive results or not.! Unfortunately, spray foam insulation is not consistently positive, but while it may boost the HVAC unit’s efficiency in general by reducing air transfer, and ensuring balanced temperature levels, it may cause discomfort by fostering high humidity levels.

This defeats the purpose of owning an HVAC device in the first place, even though the temperatures are favorable, humidity can still cause discomfort as it makes people sweaty and unappealing.

Unless you are willing to find alternative ways of getting rid of the excess humidity, installing a spray foam may not be worth it. So how does spray foam insulation trigger high humidity? First of all, humidity spikes occasionally happen after spray foam insulation in the attic because of poor quality. The corporation may have failed to seal off all leaks and vents. Thus, humid air still finds its way to the attic and the house in general. Leaking ducts can also cause a concern as it creates a downside pressure in the attic, a powerful entryway fan can also aggravate the issue. Fortunately, this is a simple one to fix! Replace the big fan with a small one and have your HVAC maintenance expert seal off all leaks. Unfortunately, these measures may not guarantee success. If this happens, then you need to install an external dehumidifier to repair the issue. Introduce an a/c in the attic to create positive pressure and minimize humidity levels. Always operate from an expert level of know-how either by consulting or conducting intense research on insulation materials.
