Energy Efficient and Rapid Response

The cooling and heating tubes are completely embedded in plaster. As a result, the heat exchange between the tubes and the plaster surface is particularly intense. This enables a uniform surface temperature with high cooling and heating capacities. Plaster cooling and heating ceilings simultaneously act as energy stores because the thermally conducting pipes embedded in the plaster also directly act thermally on the building element itself. This has a positively damping effect on the energy demand during the course of a day.

The thermographic image of a cooling or heating ceiling with, for example, a capillary tube mat, shows the very uniform surface temperature. This uniformity is indicative of excellent energy efficiency and, at the same time, a prerequisite for maximum thermal indoor comfort.

All standard plaster materials can be used for surface finish. A particularly good finish combined with high cooling and heating performance is achieved with gypsum-containing plasters. Of course, lime and clay plasters can also be applied. Thermal activation with BEKA capillary tube mats or BEKA single pipe technology also helps increase energy efficiency when using PCM-containing plaster materials. The use of machine-applied plasters is advantageous for large plaster surfaces. Guaranteed application guidelines are provided in collaboration with plaster producers.

The Invisible but Efficient Function

Plaster ceilings can be thermally activated with BEKA capillary tube mats or BEKA single pipe technology. Plaster cooling and heating ceilings do not reveal their function. Their surface is smooth and inconspicuous. If desired, however, the surface can also be structured or even provide an acoustically insulating effect for the room. Compared with other ceiling structures, plaster ceilings achieve impressively high cooling and heating capacities.

Clear Lines – Smooth Surfaces

Plaster cooling and heating ceilings are popular among many architects and builders because of their pure and simple appearance that nevertheless achieves maximum values for thermally conditioning rooms. These ceilings are very discreet in terms of room design. Minimal space is required for installing the pipes. Curved ceiling surfaces can also be activated.

It is usually very easy to renovate these ceilings. A new coat of paint can be subsequently applied at any time without significantly influencing the cooling and heating capacities.

Plaster Quality Decisively Contributes to Success

For surface finish, architects and builders can choose between many different top-quality plaster materials that have excellent physiological properties. It goes without saying that good thermal conduction is essential for plaster cooling and heating ceilings. This value decisively determines the expected cooling and heating performance. The plaster layer equalises inputted heat, thus creating a very uniform surface temperature.

Advantages of Plaster Cooling and Heating Ceilings

  • Invisible function - smooth surfaces
  • High cooling and heating capacities
  • Excellent price-performance ratio

In addition to completely embedding the cooling/heating tubes, the proximity of the pipes to the ceiling surface is of particular importance for good cooling or heating output transfer.
