They build up slowly, often without you noticing immediately . When we think of moisture, we may mainly think of the typical damp patches at the bottom of walls, but did you know that in many cases, the cause is excessive relative humidity?<\/strong>
\nThat’s precisely why an RH measurement is so useful when you’re dealing with moisture in your home. It visualizes the humidity level, which can prevent many major moisture problems.[\/vc_column_text][vc_empty_space][\/vc_column][\/vc_row][vc_row content_placement=”middle” kd_background_overlay=”gray-color” kd_background_image_position=”vc_row-bg-position-top” css=”.vc_custom_1719408216266{margin-bottom: 50px !important;border-bottom-width: 4px !important;padding-top: 25px !important;padding-right: 50px !important;padding-bottom: 25px !important;padding-left: 50px !important;background-color: #f7f7f7 !important;background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;border-bottom-color: #8dc63f !important;border-bottom-style: solid !important;}”][vc_column]

What does RH mean exactly?<\/h2>\n

RH stands for relative humidity. It is a measure of how much water vapor is present in the air, relative to the maximum amount of moisture that air can hold at a certain temperature. <\/p>\n

That last part is important: warm air can hold more moisture than cold air. That’s why humidity is always expressed as a percentage. An RH of 50% means that the air is currently half saturated with water vapor. <\/p>\n

In a healthy home, the ideal relative humidity is generally between 40 and 60 percent. Within that range, the air feels comfortable and the chance of moisture problems is minimal. As soon as that value is consistently higher, the risk of condensation (and therefore damp patches and mold growth) increases rapidly.

Why is high humidity problematic?<\/h2>\n

When warm, moist air comes into contact with colder surfaces, such as walls, ceilings, windows, or mirrors, that air can no longer hold the moisture. The excess water precipitates in the form of small water droplets. That process is called condensation. <\/p>\n

If that happens once, it’s not so bad in itself. The damp patch will dry out again and your home won’t suffer any damage. But if those condensation spots come back often or stay for a long time, then you do have a problem. It creates the ideal conditions for: <\/p>\n
