In practical terms, humidity becomes a window problem when warm air meets a cooler surface. Each of those situations points to a different cause, and they do not all call for the same fix.

Why Low-E Glass Matters In A Humid Climate

A low-E layer helps slow the transfer of heat through the glass, which is useful in both summer and winter.

First, low-E glass can keep indoor cooling from escaping so quickly in summer. Second, it can make the interior glass surface less likely to get cold enough for condensation during cooler weather. When the inside pane stays warmer, moisture has a harder time collecting on it.
