Hardiflex vs Marine plywood for ceilings

[mikey]

Are Hardiflex really advisable for ceiling use? Many say that they fall off in time due to loose nail holes which enlarge when hardinail are overdriven. Please advise.

[fortuner13]

for me mas ok hadiflex kc termite free na siya, for ceiling use HARDIFLEX LITE mas manipis ito 3.5mm, sa fall off issue I think sa pag install na yan baka kulang sa pako :) or baka hindi hardiflex nail ang ginamit, malaki kasi ulo pag hardinail hindi basta basta natanggal, on my experience ang cons lang ng hardflex both for ceiling or wall is pag may ikakabit kang mga frames or other things that used thumb tacks/cup hook or screws, and hirap ilagay n madalas nabubutas bigla yun hardiflex pag diniinan mo yun screw, hindi gaya ng plywood kakapit yun screw/cup hook kahit hindi natapat sa wood frame yun screw/cup hook

[gildred]

Para po sa akin Hardiflex lalu na sa exterior ceiling. Mas maganda nga kung yung 3.5 mm lang pag ceiling ginamit kasi di mabigat. Sinubukan ko minsan katuwaan lang, Ibinabad ko sa tubig hardiflex sabay na rin marine plywood. Siyempre pa, in time, iyong hardiflex di nabulok pero yung plywood bumigay.

[kimpOy]

imho meron ka na bang castillaje/ ceiling frame
kung wala pa mag aluminum frame ka nalang then use gypsum board

[gildred]

Sa akin lang po, pag interior ceilings, mas pipiliin ko ang gypsum board with metal furring framing system over hardiflex o plywood, dahil mas madaling i finish. Sa mga nababasang lugar, pwede rin ang moisture resistant gypsum board. Kaya lang, palagi kong ginagamit sa exterior ceiling , hardiflex pero pag may budget naman, ang gamit ko sa exterior ay spandrel panels.

[tatoski]

Gildred,

Ano ang spandrel panel?

Thanks

Tatoski

[nicolodeon]

tatoski, AFAIK a spandrel panel is sort of a...fill between the spaces of two windows: one at the bottom and one at the top. I think this is used for multi-storey places. If I'm not mistaken, this is sort of a decorative panel that is placed in between the upper sill of the lower window and the bottom sill of the upper window.

I could be mistaken though.

[Reverend Ray]

basta interior mas bagay talaga hardiflex, mga customers namin pagbumibili for interior hardiflex lagi recommend namin pati pang walls.

For interior ceilings, I usually specify Gypsum board on metal furrings for acoustic and insulation purposes notwithstanding the effciency of installing it. However, it is slightly costlier than ordinary HardyLite or Plywood per sq.m. For exterior ceiling, I suggest using Ficem boards like Jardine Products. Hardy Lite is a good alternative to ordinary plywood. Less paint, less putty used and joints are easily patched up in a jiffy.

[boybi]

Di ba nagmumukhang papel ang Hardiflex kapag nabasa? Parang nagpi-peel off sya.

[mikaztro]

Only if it has no proper paint primer and soaked in water more than 48 hours.

[boybi]

So kapag ginamit as ceiling ang Hardiflex and then nagkaroon ng tulo ang bubong, palit na rin ang ceiling?

Not necessarily. It takes more than that para masira yung ceiling mo. If it is just tulo(water drip)..no problem at all...pwera nalang kung basang basa at babad na babad sa tubig(a big gaping whole in the roof while raining hard). A good paint can also provide good protection for any material.

[boybi]

Dami ko na kasing nakitang mga naka Hardiflex na ceiling na parang carton paper na ang itsura. And kung sa ceiling ginamit yung Hardiflex, di ba yung one side lang ang mapipinturahan? Yung nasa top portion hindi na napipinturahan?

[mikaztro]

Hardiflex are made out of fiber cement board material. Yes, most constructors usually don't paint the other side. But, it wouldn't hurt if you paint the other side as well with one coat just to protect it from moisture and water leak. Ficem boards are brittle thats why you often see carton like ceilings. Quality of work(construction/installation) has more to do with it than anything else.

[gildred]

Tatoski, tama si Nicolodeon tungkol sa spandrel. Iyan ang tamang definition sa Architectural and construction dictionary... Ewan ko nga ba kung bakit itong mga manufacturer's ay ginamit ang term na iyan sa kanilang product. Anyway, ang tinutukoy kong spandrel ay ceiling panels usually made of galvanized aluminum sheet . Ang mga suppliers nito ay DNsteel, Union Steel at alam ko karamihan ng mga manufacturers ng long span prepainted roofing materials ay meron nito. Here's another link to what I was referring to: http://steelintertech.com/eng/spandrel.htm

[chieffy]

we used hardiflex sa ceiling namin...gumamit kami ng rivets sa pagkakabit nito sa aluminum frames...

wala naman problema except sa mga dugtungan/edges...solved this problem by buying wallpaper-like vinyl sheet...konting patching compund at liha lang ayos na...dun sa mga area na may rivets patching compound lang din itinapal namin...

[tatoski]

Thanks Gildred and Nicolodeon for the definition.

Tama si Chieffy there are people who use aluminum rivets to fasten hardiflex to thin gage steel furring. I've seen a lot of hamburger stores having ceilings constructed this way. They countersink the panel by pushing the drill letting the chuck act as countersink and then rivet away! Dami lang kinakabit. Spacing is quite nearer than using hardiflex nails or teks screws.

mas prefer kopadin ang plywood over the hardflex kasi mahirap maidentify kung may tulo bubong or wala since water repelant ang latter.just my 1cent

[englishman]

Hi , hope i can help , here in England internal ceilings are usually finished with a gypsum board , screwed every 8 inches to joists with a "dry lineing " screw . These screws are specially for penertrating the board and fixing to your joists .
If you are wondering what a englishman is doing on this forum its because i am hopeing to start construction on a retierment home in your country and i am trying to find out what materials and appliences are available , best regards , Englishman

[wdjbuilders]

hi guys,

have you tried using POLYCARBONATE CEILING? Ive tried it on one hospital here in cagayan de oro, they use OPAQUE or white 6mm polycarbonate as ceiling together with T-runners of course instead using acoustic boards or hardiflex or any conventional ceiling materials.

It's really squeaky clean and nice to look at. PC are fire retardant and very easy to clean and wont sag. TRY IT!

P.S.

www.wdjbuilders.com is the NEWEST and the first POLYCARBONATE IMPORTER in Mindanao based in cagayan de oro city. The cost of Polycarbonate Roof 7ft x 19f x 6mm is now very competitive/ the same price as of the SRP of CEBU and Manila, Php 5,555. We are looking for distributors and giving away HUGE discount as much as 20% for Polycarbonate Orders in Mindanao, Visayas and Luzon. We are looking for distributors.

We have office and warehouse in lower bicutan, taguig, Metro Manila.

How do you install a ceiling fan to a Hardiflex ceiling without it falling down on you?

[johnb]

I am having problems with the face side of my hardiflex ceiling boards.
they seem to be sweating, water droplets form on the face side and eventualy drop to the floor.......Its not a roof leak, and only happens when humidity levels are high. it even happens on the soffits right next to the soffit vents, recently I had to do some electrical work on the ground floor, [we have hardiflex as a suspended ceiling below our concrete floor] i had to cut access panels in the hardiflex, the pieces that i cut away i stacked together on the floor.....following day they were all soaking wet, but the ceiling was completly dry.......any similar problems? or answers? all the hadiflex sheets have been sealed and painted, they've been installed for more than two years, we had the same problem last year......advice welcomed

Regards John

Is it possible that the hardiflex ceiling is being cooled in some way? Water will condense on the cool ceiling. Think of dew drops on leaves in the early morning. A solution would be to put an exhaust fan in the room, to reduce the humidity.

[jessie2]

2diy4 is right. Heat absorbed by your house during the day is released at night. This heat warms up the humid air inside the room which in turn rises up to the ceiling. Since the hardiflex panel is not porous, it acts as a vapour barrier and does not absorb the moisture. The warm air that collects on the surface of the panel eventually cools down, condenses, and drops to the floor.

You can either put in a dehumidifier inside the room or as per 2diy4's suggestion, an exhaust fan. The only thing I would suggest when using an exhaust fan, is to use a dehumidistat controller (set at 50% humidity) instead of the regular on/off switch. With this controller, once the desired humidity is reached the fan will shut off thereby saving on electricity.

Mga pare,

Good morning. Baka naman pwede nyo akong bigyan ng tip kung paano ang pag construct ng framing para sa gypsum board. papalitan ko lang yung kwarto namin na dati ay marine plywood. Gusto ko e GI framing. Meron ba dimple guide para dyan? 3 X 3 mtrs kaya gusto ako na lang ang gumawa.

many thanks,
cengrtecs

[2diy4]

A steel stud wall is simple to do. There are two sizes of steel studs, I think a little over 2 inches and a little over three inches.

You buy studs and tracks. Tracks are installed on the floor and the ceiling. I use tox to anchor the floor tracks to the floor. I use screws to anchor the tracks to the ceiling. Make sure that the floor and ceiling tracks are aligned and "nasa hulog". Studs are simply placed at .40 centers on the tracks. Some people screw the studs to the tracks, some don't. Then the gypsum board is simply screwed to the tracks and studs.

[cengrtecs]

Good morning. Thanks for the idea, I will try to look the materials to be used sa hardware. Is there any definite hardware you can suggest sa Makati, para makabili ako ng Gypsum board at yung tracks na sinasabi mo. Usually kasi may sample sila na pinakikita.

Maraming salamat uli.

cengrtecs :)

luma na ang paggamit ng hardiflex meron na ngayon mga materials na mas maganda sa hardiflex...wanna try gypsum board...mas makapapal pa..for ceiling me mga metal type pero di kinakalawang at madaling baklasin para linisin...di pa natagos ang init sa kisame...

[opzuk4x4]

Gypsum boards have been around longer than cement boards, they both have their pros and cons. Gypsum boards are versatile and workable ceiling board....just don't get them wet. HTH!

[bonsaipinoy]

wow, lots of useful information from the pros. how do you prevent the hardiflex or plywood ceiling from showing the joints,where one board is connected to the other (I don't know the technical term), ? In large ceiling parang may tic-tac toe sa taas, specially white ceilings in unused rooms ? Sometimes the ceiling even droops in some places. Salamat po

[manggyver]

Had the same problem. It is called ghosting or thermal tracking where the joists on the ceiling became visible as shadow marks. I was told that could be of several causes: humidity, difference in inner/outer ceiling temperatures and/or soot/dust sources. After repainting, i added insulation inside the ceiling. By the way, the painter used a gray colored primer then finished it with white paint. This was done a year ago.

[bbn]

The ceiling in our office was redone by the contractor because the joints showed. I don't think it is practical to expect to remove such so it might just be better to design the joints into the design.

[opzuk4x4]

There is an epoxy based putty specifically designed for fiber cement boards, they are made by pioneer. I have tried it with gypsum mesh tape and so far so good.

Related to this query I will be using hardiflex boards for the first time, I would like to ask how dependable are they and for around 100 boards how many boxes of hardiflex nails do I need?

[opzuk4x4]

Gypsum boards has been around for decades already. It is not actually state of the art. It's a good ceiling material, a bit heavy but good all around. Just be wary of gypsum boards from china.

[WillieCapule]

I'm afraid you will never get rid of the joining, either with MarinePlywood or Hardiflex or Gysum.
They boards all have a flexibility and even if you put putty between them, the boards will move differently from the putty.
Do not be tempted to use polytuff or epoxy - even though it is a favourite here - it has no flex and will crack very easily.
The best you can do, is to really make sure you get good qulaity joining tape (Hardiflex make their own), then prime the whole surface properly against moisture.
This will minimise the cracking.

There is no way to cut corners around a professional job.

mas nauna pa lumabas sa market ang gypsum board bago ang hardiflex..... i think mga 10yrs plus bago lumabas ang hardilflex (correct me f im wrong!)

[zepol]

even plywood develops the tictactoe over time. but i've been using hf for many years now, ok naman results. i plan to use gypsum sa on areas that have no leak potential: ganda kasi ng finish.

i use textured ceiling paint. it looks nice, and hides minor imperfections nicely.
