False Ceiling

You can try the plastic coated fiberglass drop-ceiling panels.

Also, install an electric forced air vent in the bathroom that is tied to the light switch. This way the humid air will get vented out and the bathroom will smell better and reduce the chances of molds developing.

i used it in many hotels

hi,how you made false ceiling.means any kind of theory do u hv.?

actually m making project on false ceilinf,wall partition and wall panelling

can u make m help in dis

yes, I know of a solution. I can e-mail you directly on this. I have seen such a solution in industry I worked in a few years ago. Please comment in your column on this interesting problem.

Are you talking about vapours rising from the shower or bath and wetting the underside of the ceiling tiles? Or condensation dripping and falling from water line running above false (suspended) ceiling? Or both?

Yes sir i am talking about Vapours rising from the shower in rainy season

Okay, and thank you. Assuming it's India..., what I see now is a problem that appears to be worse starting at summer monsoon continuing through fall monsoon (when climate conditions are rainy and humid), and then continuing through late fall/early winter (with cooling climate)...until hot/drought season returns.

I am also seeing a room that has lighting and electrical service to it—possibly running through the space above the suspended ceiling?

It is not clear, yet, whether or not the shower area (where nozzle or nozzles are located ) is located in a niche (what some people call, a shower stall) within a larger room, or occupies the entire room...so that the entire suspended room ceiling is subjected to vapor condensation?

To help me provide better-targeted suggestions, please tell me if the above is correct, and/or what parts need correction.

In the meantime while you prepare your answers, here are a few things to think about—including one unusual idea that might not have occurred to you. ... first the unusual part.

You are seeing an association between your ceiling tile problem and cooler or wetter conditions because those are the times at which the problem is most noticeable as condensation on the ceiling tiles. While ceiling tile absorption of this condensation does present a problem (with potential tile degradation and damaging or unhealthy fungus growth), in another sense the condensation also works to advantage: because condensation tends to coalesce and drop floor-ward, where it drains with the shower water, or can be wiped or mopped away.

Similarly, you might not think of the hot, dry season as a problem because there is no, or far less, condensation. In actuality, however, you should be concerned about that (the hot, dry period) as well, because non-condensing/evaporated vapours that reach the ceiling (when air and ceiling tile temperatures are above the dew point), rather than condense, are more likely to find gaps (along the ceiling-tile-support T-bar grid) through which to "penetrate" to the (probably cooler) space above the tiles....where, over time, they can condense and cause unseen damage (including mold, tile damage, and rusting of tile support grid and hangers). For these reasons, I believe your "solution" needs to be more "holistic" than merely preventing condensation from wicking up into the tiles.

Now, speaking only to your original question, and to the condensation aspect, whatever you could do now to prevent wicking of condensation into the tiles would be beneficial. This could be as "complicated" and costly as replacing ... with moisture-impervious tiles—tiles manufactured and sold specifically for "high-humidity" environments—either throughout the room or over spaces where significant condensation occurs; or as simple as painting your existing tiles with "waterproof" (e.g., "high-gloss enamel") paint. Either of these "tile moisture resistance" solutions would be a good starting point....

Looking at the bigger picture, the holistic solution: the primary means (other than wall and ceiling impermeability) by which humidity control is typically achieved is by ventilation; either natural ventilation via a window opening (where climate and comfort permit), or forced ventilation using various forms of ducting and choices of electrical exhaust fan types, or both.

We can talk more about ventilation after you return with those clarifications I asked about above.

Also, if it would be possible for you to make and post a simple drawing (or annotated photo) depicting your shower room (preferably it would also show plumbing areas, location of changes in ceiling heights, light switch locations, window and entry door locations, and electric-service wire run locations), that would probably help a lot towards discussing a good plan. Remember to use thick lines and big letters in your drawing so the drawing shows up clearly when posted.

Dear sir

regarding bathroom , : you can make the false ceiling by aluminum tiles ro galvanized metal to avoid the rust, other measure is to provide special drain to collect the condensed water on the pipe and send the collected water direct to main drain line .

the hot water pipe can be put under the false ceiling then ceiling can be painted anti moist and waterproff paint .

Insulation on the cold pipe at least.

Dear, you can use bold wire between 2 ceilings boards and do min space in false ceilings.
