Engineering and Production The construction and details to be created are defined based on the basic analysis. The CAD service “planning” supplies layouts, views, floor plans, perspectives and variations. The CAD service “implementation” creates the production and installation plans, instructions for the suspension, quantity take-offs, overview, documentation and presentations as well as scheduling. Our production stands for efficient processes and reliable, expedient processing.

▼

Consulting and Planning Each project at Armstrong begins with a clarification of the needs, and in-depth consulting with the architect or general contractor: Which functionality is the ceiling to provide, and which requirements must the ceiling construction satisfy? Technical clarifications include the room size and the ceiling suspension height, the composition of the rough ceiling and wall, and questions about materials' composition, production, installation and static loads.

Maintenance and Support Armstrong also offers worldwide customer service when adaptations or expansions of existing conditions take place. We maintain partnerships with top-notch installation companies around the world, which we also recommend for repair or even cleaning work in addition to installation.

Logistics and Installation Each project is unique. That is why Armstrong develops a project-specific logistics concept for each project as basis for on-time execution. In order to ensure proper installation, we supply detailed instructions or manuals to the companies assigned to carry out the installation and also offer construction site support.

Air-conditioning systems of today Most air-conditioning systems use the principle of forced air. In forced air-systems, warm room air is recirculated and chilled, and blown back into the space. With the increased use of PCs and other office technology, higher and higher heat loads need to be removed from these environments. To remove this additional heat, a higher volume of cooler air is blown into the working environment to maintain comfort, making draft-free cooling with chilled primary air increasingly more difficult. An additional problem that came to light in the 1970s and 1980s is known as “sick building syndrome”. Bacterial herds in air ducts can contaminate the air and make people ill. With forced-air systems, typically 80 to 90 per cent of the forced air is recirculated. This high level of recirculation promotes the spread of potentially harmful and/or odor causing organisms. A new air conditioning concept Hydronic radiant cooling technology enables air conditioning to occur in a completely different way – a way that solves both problems. Radiant cooling ceiling panels contain chilled water running through pipes that are bonded to the non-visible side of the panels. The ceiling panels function as heat exchangers between the room air and the chilled water. The ceiling absorbs heat from heat sources in a room and exchanges it with the circulating chilled water. The chilled water is pumped to a chiller, recooled, and returned to the ceiling.

Configuration of a Radiant Cooling Ceiling Principle Technically speaking, a radiant cooling ceiling is simply a large heat exchanger suspended from a room’s ceiling. It exchanges energy via the room’s radiation and convection. Accordingly, cooling ceilings can be rated. Calibrated precision copper tubing The precision diameter copper tubing that is pressed into the heat conducting rails allows the smallest possible pressure drop and an optimal heat transfer between chilled water and copper tubing. The large inside diameter ensures there is no clogging or flow noise. The wall thickness ensures that there is plenty of strength to withstand the working pressure of the system. In addition, the wall thickness prevents damage, such as pitting and cavity formation on the interior surfaces caused by undesired contamination particles that may be in the water.

Impact of Radiant Cooling Ceilings The cool surface of a radiant cooling ceiling is an ideal radiation partner for the skin. The capacity for the quiet, very comfortable heat exchange process that occurs via radiation is almost doubled with the use of radiant cooling. The rate of convection and, espe cially, evaporation are reduced, and air drafts in the room are reduced to a minimum. Radiant cooling ceilings enable pleasant, draft and noise-free air conditioning.

Transport Energy

Ceiling Installation

Basically, an air conditioning system needs energy to cool, plus energy to transport the cooling medium from the chiller to the room and back again. Conventional systems remove heat with air. However, most radiant cooling systems use water as the cooling medium, and water has more than four times the capacity to absorb heat than air does. In other words, one kilogram of water can absorb four times more energy than one kilogram of air. Therefore, to absorb the same amount of energy with water, four times less mass needs to be transported to absorb the same amount of heat.

The cooling elements that are bonded to the ceiling panels have little or no influence on the ceiling installation. The same subconstructions and suspension systems that are used with conventional ceilings also may be used with radiant cooling ceilings. Building service equipment such as light fixtures, loud speakers, sprinklers, and diffusers can be integrated in a cooling ceiling. When possible, building service equipment is added to inactive panels. An elegant way to handle items that need to be installed in every zone (such as diffusers, fire detectors and loud speakers) is to install them all in the same panel. When building service equipment must be added to an active panel, the heat- conducting rails on the underside of the panel can be either discontinued or the distance between them can be extended.

Capacity The capacity of a cooling ceiling is influenced by many different factors. Some of the most important factors include room height, the difference between room temperature and average chilled water temperature, the plac ing of the heat loads in the room, air inlet distribution, the percentage of active area, the temperature of the surrounding surfaces in the room (hot facade, etc.), and the construction of the cooling ceiling.

Architecture Because architectural implementations can influence thermal comfort and general wellbeing, radiant cooling systems are designed to promote architectural freedom in several ways. First, radiant cooling ceilings can be designed to be visually indistinguishable from regular ceilings to maintain aesthetic appeal. Secondly, the hardware in a radiant cooling system is smaller and more flexible.

Acoustic Fleece The black fleece is bonded to the rear of the perforated ceiling panel. To prevent a dec rease in the heat exchange between the heat conducting rails and the ceiling panel, the fleece is bonded between the heat-conducting rails. Special Perforations/Constructions The Ultramicro® perforation by Armstrong has practically the same acoustical effect as the fleece or the acoustic inlay mats. A further possibility for absorbing sound is the use of special acoustic elements that can be configured in the plenum.

Acoustic Armstrong metal ceilings are ingeniously functional acoustic solutions. Noise is absorbed where it would be distracting while speech and sound are directed to zones where sound is desirable. Thus, Armstrong metal ceilings influence the acoustic characteristics of a room to meet specific expectations.

People are immersed in sound all the time. Since a person’s well-being and hearing quality depend on the acoustics of a room, this aspect should be carefully considered in the planning and design phases.

Terminology of Acoustics Airborne Sound Insulation With airborne sound insulation or barriers, the passage of airborne sound is reduced by a solid separation element. The sound energy is reflected by the insulation element and simultaneously absorbed by the insulation material. The sound insulation effect (in dB) increases with the density of the material. Insulation = reflection of sound. Sound Reflection The systematic deployment of reflecting materials can positively influence the overall acoustics of a room. For instance, this is the case in training and seminar rooms where the speaker’s voice is uniformly distributed by means of strategically placed sound reflection zones.

Sound Absorption Typical absorption values αs with Armstrong standard perforation Rg 2516: Acoustic non-wovens 61 g/m2 full-area bonded Acoustic mat 25 kg/m3 15 mm, exposed side lined with black fibreglass non-wovens, back side with aluminium foil Acoustic mat 60 kg/m3 40 mm, exposed side lined with black fibreglass non-wovens, back side with aluminium foil Mean absorption values αω for Ultramicro®, Extramicro, micro, standard, and special perforations Qg 4025. Armstrong has conducted numerous systems-specific acoustic tests. Please contact your Armstrong consultant to obtain applicable certificates.

Sound Insulation Longitudinal Sound Insulation with Horizontal Barriers Normally, horizontal barriers are installed in ceiling panels as a com bination of insulating and absorbing materials. The solid elements reflect the sound while acoustic inlays absorb it. The ceiling insulation value should correspond to that of the wall. Longitudinal Sound Insulation with Vertical Bulkheads The ceiling itself can be either just absorbent or also have insulating properties. The vertical bulkheads prevent sound propagation through the ceiling cavity with a soundstop installed above the partition wall. The total ceiling insulation value should correspond to that of the wall.

One of the key functions of a metal ceiling is to create a pleasant atmosphere enhanced by intelligent noise abatement. Armstrong perforations offer a vast spectrum of very aesthetic solutions for effective acoustic comfort. Depending on the intended purpose of a room, reverberation times will need to be optimised as well. This parameter depends on the total absorption capacity of the room.

Colours 10 4

Colour is a physical phenomenon and a sensory impression perceived by our eyes. It is triggered when light rays reach the retina and generate colour stimuli, which the brain transforms into colour information. Light is electromagnetic radiation which travels through space in waves, similar to the ripples in a pond caused by a stone. The wavelength of visible light ranges from about 380 nm (violet) to 750 nm (red). The eye perceives each wavelength of visible radiation as a certain spectral colour. The sequence of these colours corresponds to the colour configuration of a rainbow. A distinction is made in light rays between long and short-wave rays. The warm colours (sunset red) are long-wave, the cold colours short-wave radiation.

Reflectance [%] Reflectance

R [%] 100

Reflectance plays a significant role in colour perception. The amount of reflected light depends on the colour and texture of the surface. The brighter the colour, the more light it reflects. A pure white surface will reflect nearly 100 percent of the incident light while a black one will absorb nearly all of the light. Armstrong standard ceilings finished in RAL 9010 Pure White thus help save considerable illumination costs. The light incidence angle and the light source (sunlight or artificial light, for instance) also influence the effect of colours to a great degree.

Gloss The way in which incident light is reflected by a surface depends on its texture. Smooth surfaces exhibit more gloss than textured ones. The light reflected at an angle of 60 degrees is measured and compared with the incident light. The ratio defines the degree of gloss. Armstrong’s standard RAL 9010 Pure White colour with a satinsmooth finish has a degree of gloss of about 22 per cent, measured according to Gardener and DIN 67530.

Ecology and health The Armstrong standard RAL 9010 Pure White powder coating con sists of organic binders based on polyester and epoxy resins, small amounts of additives, and inorganic as well as organic pigments for colour. It contains no heavy metals and TGIC. Thus, the coating is not subject to any toxicological classification or identification requirements. Under thermal loads, it does not emit any combustion products apart from those generated when burning other organic substances such as wood, oil, or household waste.
