StoCalce Functio
State-of-the-art humditity management
Overview
If there‘s one basic rule for creating a pleasant ambient interior climate, it‘s maintaining the humidity at a level that is neither too high nor too low. There are, however, rooms and geographic locations in which the climate poses a particular challenge.
By harnessing the unique benefits of lime and loam, we have taken humidity management to a whole new level. Thanks to its porous structure, loam is able to store humidity temporarily before releasing it back into the environment at the appropriate conditions. While lime offers durability, design and application advantages that have stood the test of time.
Introducing to the market – StoCalce Functio, an interior plaster system, that is nothing but natural, offers a variety of unique surface finishes and can regulate the ambient interior climate perfectly.
