Technical Reference

Installation

Acoustical ceilings that are unsatisfactory in appearance are often the result of poor application or disregard of the manufacturer’s instructions. Here are a few recommendations to consider when designing with and specifying an Armstrong ceiling system.

Jobsite Conditions

Before Armstrong ceiling materials are installed, the units (ceiling panels or tile) should be permitted to reach room temperature and have a stabilized moisture content. They should not, however, be installed in spaces where the temperature or humidity conditions vary greatly from the temperatures and conditions that will be normal in the occupied space (exception: RH 100 performance ceiling tiles). Some Armstrong ceiling materials are more abuse-resistant than others. It is not good practice to locate acoustical ceiling tile or panels on low wall or ceiling surfaces where they might be damaged. Dirty air can soil any ceiling, although ULTIMA™ and OPTIMA have superior resistance to soiling. Proper design for both supply air and return air, and maintenance of the HVAC filters and building interior space are essential to minimize soiling. Before starting the HVAC system, make sure supply air is properly filtered and the building interior is free of construction dust.

Temperatures and Humidities

During Installation

Acoustical materials are interior finish products and are designed for installation to be carried out in temperature conditions up to 86°F (30°C) in spaces where the building is enclosed and HVAC systems are functioning and will be in continuous operation.

There shall be proper ventilation of the plenum in high moisture areas. All plastering, concrete, terrazzo or any other wet work should be complete and dry. All windows and doors should be in place. The heating, ventilating and air-conditioning systems should be installed and operable, where necessary, to maintain proper temperatures before, during and after installation of the acoustical material. Note: The preceding restrictions do not apply to ceilings with RH 100 performance. One side, always install the vapor barrier in the down position facing the back of the ceiling panel. If the use of batt insulation is required, limit use to 24”x 24”panels (use only non faced batts maximum R-19).

Thermal Insulation Mineral Ceilings

The use of overlaid insulation placed on, and supported by, mineral ceiling panels is not recommended.

The additional weight supported by the panel could result in panel sag in high humidity conditions. If job requirements are such that insulation is necessary at recommended occupancy conditions, limit such insulation to a maximum of .26 lb/ft2(R-19 Fiberglass). Only roll insulation is recommended and must be applied perpendicularly to the cross tees with the grid supporting the weight of the insulation. For roll type insulation that either has a foil or kraft paper vapor barrier on Thermal insulation should not be installed on the back of Fire Guard panels in a fire resistive ceiling membrane unless so designated in the specific UL roof/ceiling or floor/ceiling design assembly assigned to the structure; i.e., P265 or P250.

Fiberglass Ceilings

Armstrong fiberglass ceiling panels are recommended for use when additional thermal insulation is required to be overlaid on the back of the ceiling panels. Specific limitations apply. Please contact TechLine for specific fiberglass backloading recommendations.

Selecting Lighting

When selecting any type of lighting, it is important to evaluate the fixtures (lighting system) and ceiling panels or tile as components that work together in an integrated system. Important considerations include both initial and long-term costs, energy consumption and perhaps even the lighting system’s potential impact on worker effectiveness within the space. It is also always advisable to consider the effect it will have on the appearance of an acoustical ceiling. Unfavorable ceiling appearance may be produced by light striking the ceiling surface at small angles. This condition most frequently occurs with ceiling edge lighting from fixtures, cove lighting and/or high windows. This will accentuate minor surface variations that are beyond the control of manufacturing standards for mineral fiber. Further, minor differences in paint gloss often are magnified by these conditions. Mitigating the problem is best handled at the lighting source with proper shading, diffusing and/or light redirecting devices.

Maintenance

Armstrong Ceiling Systems require no more maintenance than painted DRYWALL ceilings. However, when maintenance is necessary, certain procedures should be followed to insure continued high performance and attractive appearance. Dust and loose dirt may easily be removed by brushing or with a vacuum cleaner. Vacuum cleaner brush attachments such as those designed for cleaning upholstery or walls do the best job. Be certain to clean in one direction only. This will prevent rubbing dust into the surface of the ceiling. After loose dust has been removed, pencil marks, smudges, or clinging dirt may easily be erased with an ordinary art gum eraser. However, a good grade wall cleaner may be preferred. Be certain to use fresh cleaner. Most Armstrong mineral fiber ceilings may be cleaned with a moist cloth or a sponge dampened in water containing mild soap. (This does not apply to cloth-faced ceiling panels.) The cloth or sponge should contain as little soapy water solution as possible. After washing panel face, any moisture remaining should be wiped off with a dry cloth. Bioguard, FINE FISSURED Ceramaguard ceilings, and Mylar-faced ceilings are less affected by moisture and will withstand repeated washings with mild detergents or germicidal cleaners.

Painting Recommendation

Precaution

Armstrong recognizes that ceilings may be repainted and will make recommendations for the type of paint that may be used. However, Armstrong cannot be responsible for the finished appearance or performance for the field-painted acoustical material. Armstrong cannot guarantee that the published surface burning characteristics, fire resistance ratings, acoustical performance, dimensional stability (sag), or light reflectance will remain the same after repainting. All warranties will be voided by field painting. When painting acoustical materials, the painter should be very careful that he/she does not close up the perforations or fissures in the material. It is through these openings in the surface that sound waves enter the body of the acoustical material and are absorbed. Care should be taken that these perforations are not clogged. Spray painting will result in a more uniform coating on embossed or irregular surfaces. For best results, panels should be removed from grid suspension system, laid flat for painting, and allowed to dry thoroughly while still flat before reinstallation. This method eliminates the costly operation of masking walls and covering furniture. It also provides for easier cleaning and/or repainting of the grid while the panels are being repainted. Field painting of laminated faced products is not recommended. The variations which are possible in field-painted applications could affect fire performance.

Painting Method

First remove loose dust from the material with a brush or vacuum cleaner attachment. Thin the paint only as much as necessary. If it is too thick for proper spraying, care should be taken that it is thinned only as recommended by the paint manufacturer. When spray painting, apply the paint with a stream directed perpendicularly to the surface of the material, moving the gun back and forth to get a uniform coating. Under normal conditions, one coat should be sufficient.
