Ways to reduce humidity while having spray foam insulation

Before installing any insulation, it helps to research expansively to suppose if such a move will yield positive results or not! Unfortunately, spray foam insulation is not consistently positive.

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, and this defeats the purpose of owning an HVAC component in the first location, however even though temperatures are favorable, humidity can still cause discomfort as it makes people hot 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 sometimes happen after spray foam insulation in the attic because of exhausting quality. The business may have failed to seal off all leaks plus vents, thus, humid air still finds its way to the attic and the house in general, however leaking ducts can also cause a problem as it creates a negative pressure in the attic. A powerful living room fan can also aggravate the issue. Fortunately, this is an easy one to fix, then 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 maintain the issue. Introduce an a/c in the attic to create positive pressure and minimize humidity levels. Always operate from an expert level of knowledge either by consulting or conducting intense research on insulation materials.
