Default Re: Hardiflex vs Marine plywood for ceilings


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

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

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.

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?

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
