    Re: Hardiflex vs Marine plywood for ceilings

    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.

      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

        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...

          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

              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

                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?

                    Re: Hardiflex vs Marine plywood for ceilings

                    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.

                        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

                            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.

                              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.

                                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...
