Plaster Radiant Ceiling - Ceiling Heating and Cooling Using Plastering Techniques

Plaster ceilings on bare concrete can be thermally activated using either BEKA capillary tube mats or 10 mm single-tube technology. A plaster cooling ceiling does not reveal its function. The surface is smooth and discreet as standard. The plaster ceiling can also be given texture for design emphasis. Modern clay or lime plasters can have a positive effect on humidity regulation, indoor air quality, and room acoustics. In large rooms, additional acoustic slats can be used to control the room acoustics. Compared to other ceiling constructions, plaster radiant ceilings achieve very high heating and cooling performance.

Benefits of a plaster cooling ceiling

  • Invisible function – smooth surfaces
  • Large-scale design
  • Optimal heating and cooling performance
  • Particularly economical for large ceiling areas

Why use a plaster ceiling for radiant heating and cooling

Plaster ceilings are popular with many architects and builders precisely because of their simple appearance. In terms of interior design, this type of ceiling recedes into the background. Renovating plaster ceilings does not require a great deal of effort. A new coat of paint can be applied at any time without significantly affecting heating and cooling performance.

The plastering process is ideal for ceiling heating and cooling. It is highly efficient and requires minimal space for pipe installation. Even curved, uneven ceiling surfaces can be thermally activated in this way.

Which plaster provides optimal support for the heating and cooling function?

The radiant heat exchangers are completely enclosed by plaster. This makes the heat exchange between the pipes and the plaster surface particularly intense. The result is a uniform surface temperature with high heating and cooling performance. The entire plaster ceiling becomes an energy storage medium because the heat-conducting pipes in the plaster also thermally activate the component itself. This has a positive effect on energy consumption throughout the day.

The thermographic image of a ceiling heating and cooling system using the plaster method with capillary tube mats clearly shows the very even surface temperature. This evenness is an expression of high energy efficiency and at the same time a prerequisite for high thermal comfort in the room.

In principle, all standard plaster materials can be used for surface design. Gypsum-based plasters achieve particularly good workability combined with high heating and cooling performance. Of course, lime or clay plasters can also be worked well. For large plaster surfaces, the use of machine-applied plasters is advantageous. The use of PCM-containing plaster materials contributes to an increase in energy efficiency when used with thermal activation by BEKA capillary tube mats or single-tube technology.

The BASWA Cool System can be used to create sound-absorbing acoustic cooling ceilings. In cooperation with plaster suppliers, reliable processing guidelines for plaster ceilings are available.

Impact of plaster quality on the energy efficiency of a cooling ceiling

Architects and builders can choose from a wide range of plaster materials and qualities with specific physiological properties for surface design. When planning ceiling heating and cooling using plaster, good thermal conductivity is important. Thermal conductivity, together with the thickness of the plaster, has a decisive influence on the expected heating and cooling performance. The plaster layer ensures that the heat is distributed evenly, thus contributing to a uniform surface temperature.

In addition to the complete embedding of the capillary tubes in the plaster, the proximity of the tubes to the ceiling surface is particularly important for good heat and cooling transfer.
