Metal and plastic in unison – with good effect

At first sight, it might seem that the connection between the metal ceiling panels and plastic capillary tube mats would not provide particularly good thermal conductivity. However, the underlying principle behind capillary tube technology also provides a decisive advantage here.

It is not just the thermal conductivity of the tube material that is important, but rather the heat transfer resistance considered over the entire surface. The thin capillary tubes are only 10 mm apart. This creates a very uniform surface temperature.

The Number of Capillary Tubes Is what Gives the Advantage

The capillary tubes used in the capillary tube mats for thermally activating metal ceiling panels are only 3.35 mm wide, have a wall thickness of just 0.5 mm and are only 10 mm apart. In addition, capillary tube mats can be manufactured to fit precisely into almost any size of metal ceiling panel to an accuracy of just a few millimetres. This enlarges the thermally active surface of the ceiling. BEKA capillary mats typically used for activating metal ceiling panels are K.G10, K.U10 or K.UM10 compliant.

The flexible, thin capillary tubes also easily adjust to the uneven surface of the ceiling panels. It is advantageous to bond the capillary tubes in the ceiling panels. However, this bonding should also remain flexible. A rigid bond, as in the case of the serpentine copper tubing, is more prone to degassing under the effect of temperature, which considerably reduces the heat transfer from the panel surface to the heat-conducting tubes.

Advantages of Metal Acoustic Ceilings with Capillary Tube Technology

  • Format-independent, maximum activation
  • No influence on the acoustics
  • Good price-performence ratio

Fast and Simple Assembly

BEKA capillary tube mats are produced with an accuracy to the nearest millimetre to perfectly fit the dimensions of the corresponding panel format. At the customer’s request, capillary tube mats can already be expediently bonded into the corresponding metal ceiling panels in the factory. The individual panels with the glued-in capillary tube mats can also be itemised in a project-specific parts list at BEKA. This service helps avoid unnecessary sorting work on the construction site. Of course, the construction team can also insert the capillary tube mats directly into the metal ceiling panels on the construction site. This is particularly interesting for retrofitting projects. It is also beneficial to cover the capillary tube mats with mineral fibre insulation (sealed in PE film) when this structure is also used to press the capillary tubes into the panels.

Capillary tube mats are connected quickly and reliably to each other and to supply pipes via flexible hoses and plug-in connector technology. The supply pipes can be prefabricated by BEKA from polypropylene tubing with inserted plug-in couplings. You can find this product line under Product Group Z.

When bonding the capillary tube mats to the metal ceiling panels, it is important that the individual capillary tubes have good heat-conducting contact with the metal ceiling panels.
