Frequently Asked Questions
What are Armstrong ceilings made of?
Armstrong mineral board ceilings are made of inert mineral components, binders and inert filler materials. They consist of up to 55% recycled content: newsprint and mineral wool. Armstrong also offers high performance engineered resin and durable laminate plank ceilings.
Can I put insulation on the back of an Armstong ceiling?
Only Armstrong suspended ceiling panels (2' x 4') that are at least 5/8" thick can be back-loaded with additional insulation. Rolled insulation must be used and installed perpendicular to the cross tees so that the weight of the insulation rests on the suspended grid system, and there is air space between the insulation and the panel. Ask your dealer for specific details.
What about the insulation value between floors?
Most ceilings are installed between floors that are maintained at the same temperature - making insulation unnecessary. Basement recreation rooms are at least partly heated by heat flow through the ceiling from the heated space above. In that case, attempting to insulate the basement ceiling surface could actually reduce heat flow.
Can Armstrong ceilings be painted?
All Armstrong wood and mineral fiber ceilings can be painted with latex paints once surface dirt has been removed. Fiberglass panels should not be painted. Note: Armstrong cannot guarantee fire performance rating of a repainted ceiling.
Will painting acoustical ceilings affect acoustic efficiency?
Armstrong acoustical ceilings can be painted with a slight loss of acoustical efficiency using nonbridging paint that does not cover the holes.
Can ceiling tile be used in the bathroom?
Yes, if the bathroom is vented to the outside with a fan. Armstrong ceilings with HumiGuard Plus are extra sag resistant for use in areas of high humidity. BioBlock paint treatment inhibits the spread of mold and mildew.
Should mineral ceiling materials adjust to room temperature before installation?
Yes. Unpack ceiling materials 24 hours before installation to allow product to adjust to normal room conditions. Do not install during excessively humid conditions. Mineral ceiling products should be stored and installed in areas with a normal temperature range of 60 to 80 degrees Fahrenheit and not exceeding 70% relative humidity, except HumiGuard Plus ceilings, which can be used in temperatures ranging from 40 to 120 degrees F, and anywhere standing water is not present.
Can the ceiling be installed over embedded radiant-heat coil ceilings?
No. An appreciable loss of heating efficiency will result and the ceiling will not remain stable.
Can a hanging or swag lamp be used with an Armstrong ceiling?
Yes, if supported independently by an existing structural member.
Can a new ceiling be cemented directly over old ceiling tiles?
It is best to remove old tiles first. In many cases, the old ceiling may have deteriorated and an adequate hold cannot be obtained.
How much will a new ceiling cost?
Not as much as you think! Costs vary according to product design and performance features. Ceiling product costs for a new ceilng in a 10' x 12' room would range from $50 - $200.
What is the minimum overhead distance required for a new suspended ceiling?
Armstrong suspended ceilings require a minimum of 3" (6" if installing recessed lighting) of overhead clearance. Suspended fiberglass ceilings require a minimum clearance of 2-1/2". OptiGrid reduces clearance needs to only 1-5/8".
Can existing light fixtures be used with a new ceiling?
Yes. Armstrong ceilings are adaptable to standard lighting fixtures.
What kind of fluorescent lamps should be used with Armstrong ceilings?
All lamps must be rapid-start. Warm white and cool white are most efficient, but deluxe and natural-colored lamps provide a more pleasant atmosphere.
How many fluorescent lighting fixtures will I need for a new ceiling?
Standard rule for light fixtures is two 4' fluorescent tubes for every 75 square feet of suspended ceiling.
Will the ceiling sag over time?
No. Armstrong ceilings are treated with a special back coating to resist moisture. When properly installed under the right conditions (no excessive humidity, etc.), they remain level and flat. We recommend using HumiGuard Plus panels or fiberglass panels in areas of high or seasonal humidity they are not recommended for spaces exposed to continuous moisture.
Do Armstrong ceilings protect against flamability?
All Armstrong ceiling panels, tiles and planks are fire-retardant and need Class A flame-spread ratings with the exception of WoodHaven planks, which meet Class C flame-spread ratings.
Where can I get product warranty information?
Detailed product warranty information is included in every ceiling product carton. See the Armstrong web site for more information www.armstrong.com
