Advantages of Metawell® radiant and acoustic ceilings
- Heating and cooling with one system
- Lower energy consumption, since the perceived room temperature can be set 1-2 °C lower
- Less space requirements in the ceiling cavity and in the technical centre, since water is a better energy source than air
- Hardly any maintenance costs
- The high performance allows a lower occupancy density
- Fast and easy installation
- Quick reaction time because of the excellent heat conductors aluminium and copper
- Less sickness-related absenteeism
- Improved performance of employees
- Radiation heats like the sun
- No noise disturbance
- No noticeable draft
- No whirling up of bacteria and dust
- Good room acoustics due to high sound absorption
- Equal temperature level in the room
- Various contour and edge geometries
- Different surfaces and coatings
- Unlimited flexibility in planning, room design and room layout
- Easy installation of sprinklers, lamps, maintenance flaps
- Thin ceiling construction thanks to low construction height
- Low weight
- High load capacity by sandwich structure
- Unique flatness
- Also suitable for retrofitting
- Especially in office and administrative buildings, hospitals, sports halls …
- Suitable for every floor plan
How does a radiant ceiling work?
The term radiant ceiling refers to a suspended – frequently also sound-absorbing – ceiling, which can heat and cool a room. Radiant ceilings work like the sun by means of radiation. When heating warm water flows through the copper pipes on the backside of the panel. In the cooling phase, the Metawell® ceiling element absorbs the heat radiation of the room, whereby the floor, walls and furnishings cool down and as a result the room temperature drops.

Comfortable and healthy
Radiant ceilings fulfil important requirements on the room climate and promote comfort. Conventional air conditioning systems often do not provide a satisfactory solution because air is not an effective heat transfer medium. In addition, the draft required for cooling is not only felt as unpleasant, it also whirls up dust and germs.
Other advantages resulting from the air conditioning with radiant ceilings are greater comfort and well-being for the employee, which increases the performance of the employee and reduces illnesses and absenteeism.
Energy-efficient and cost-saving
The decisive factor is the operative room temperature felt by the employee, which is also called the sensation temperature. This designates the average of the ambient air and surface temperature of the enclosing areas. In rooms with radiant ceilings, the room air temperature can be set between 1 – 2 ° C lower than the room air temperature with pure air cooling, but with the same perceived comfort. In building technology, heating is expected to save 6 % in energy costs per 1 ° C lowering the room air temperature. In the cooling phase the savings are even higher, because heating is technically cheaper than cooling.
Metawell® radiant ceilings consist of the two particularly good heat-conducting metals aluminium and copper. In comparison to other steel or plasterboard systems Metawell® reacts extremely fast and reaches higher performance values.
Radiant ceilings are space-saving, since no radiators reduce or impair the usable space and no large-sized air ducts are necessary in the ceiling cavity. The converted building volume is therefore reduced with the same usable space.
Tightness and compliance with the warranted performance values are guaranteed by the following precautions:
- Use of continuous tubes only
- All pipe ends are calibrated and provided with a protection cap. Pipe ends that are connected via plugs are stiffened with support sleeves
- Panel coating, glue, heat conducting profile and copper pipes are optimally adjusted to each other
- The copper tubes are manufactured and assembled with machines developed especially for series production
Sound absorption is almost always a problem in modern office buildings, since large windows and core-tempered buildings represent sound-hard surfaces. For relaxed communication, special attention must be paid to the room acoustics.
Using perforated Metawell® radiant ceilings is a good idea. If this is not possible anymore, perforated acoustic ceiling elements without cooling and heating function can also be installed afterwards. Their decisive advantage is that they do not have a thermally insulating effect. So the performance of already installed radiant ceiling surfaces is not reduced at all or only to a small extent.
The high rigidity of Metawell® allows the statics to be weakened by large cutouts for recessed luminaires and high lamp weights, e.g. with pendant lights. As a rule, it is not necessary to hang the lights separately from the raw ceiling. This leaves the lighting technician a great scope for design and saves installation costs. By varying the size of the perforated fields, the surface color and the degree of gloss, light reflection can be customized to the needs of the user, especially with floor lamps and floodlights.
For radiant ceiling sails using LED lights is possible as well. The small lighting can be positioned between the copper tubes, so the heating and cooling capacity is not reduced. The pendants can also be attached subsequently through the existing perforation. For example, pendants with a weight of up to 7.5 kg can be attached to the panels without additional reinforcement. The power cable can be led through the perforation to the backside of the panel.
