Humidity adsorbent, also known as molecular sieve, is usually placed inside the spacing profile of an IGU. The presence of a humidity adsorbent of a decent quality is the least expensive insurance policy for an IGU.

The IGU durability is determined by the dynamic balance between the amount of moisture that penetrates into the unit and the amount that the adsorbent can absorb. If the amount of steam crosses the dew point, the steam can condense.

Depending on the IGU construction, if the unit is ideally sealed, its durability can range from a dozen or so to over a hundred years. Minor leaks can significantly limit the IGU lifetime. Doubling the adsorbent amount in profiles extends the IGU durability even sixfold.
