The technology of concrete and
masonry construction with its narrow designs, the rational production techniques
and the continuous improvement of the quality of acoustic and heat protection
has reached an impressive level. Only with the rendering/plastering of walls
and ceilings does the unreal appearance of the shell complete the step towards
being an acceptable building.
Gypsum, with its specific building material properties, always ensures warm surfaces to building units and a pleasantly regulated humidity within the room – regardless whether it is a dwelling, office or public building. It is only after plastering that the shell is sealed, heat remains in the rooms, heating energy is saved.
Warm home comfort
The characteristic of water absorption is shown by a row of building materials – not always an advantage for the building. The procedure with gypsum turns itself into
something useful as the material also gives up the water again under changed
room climatic conditions. Through this, the climate of the room is regulated: the extremes of too moist or too dry room air are toned down, the humidity of the air always remains in a comfortable range. The surfaces of the gypsum are not only dry but also feel pleasantly warm. Other than the example of marble or metal, gypsum radiates no low temperature effect to the surface of the building.
The material belongs to the healthy living building materials. The reasons are the
many small pores which work as heat buffers in front of the cold wall or ceiling. The heat conductibility λ of MultiGips interior plaster is, with values between 0.2 and 0.35 W/mK, distinctly small.
