Spray foam insulation can cause a spike in humidity

Before installing any insulation, it helps to research extensively to think if such a move will yield positive results or not, but unluckily, spray foam insulation is not always 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, but this defeats the purpose of owning an HVAC component in the first venue. Even though 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 exhausting quality. The contractor may have failed to seal off all leaks and vents, and humid air still finds its way to the attic and the home in general. Leaking ducts can also cause a problem as it creates a drawback pressure in the attic, a powerful fan can also aggravate the issue, fortunately, this is an easy one to fix. Replace the big fan with a small one, and have your HVAC service expert seal off all leaks. Unluckily, these measures may not guarantee success, and if this happens, then you need to install an external dehumidifier to fix the issue. Introduce an a/c in the attic to create positive pressure and minimize humidity levels. Always operate from an expert level of comprehension either by consulting or conducting intense research on insulation materials.
