Sure you'll appreciate this







Bloody hot here... lot's of people doing like this.

Guy who's doing the work said we only needed to add some chb and we'd have a new house... think I'll get him to do the roof out the back first and then we'll add the concrete and chb (or hardiflex)

Should have fitted the white (heat reflective) roof panels though...as I have on our new 2nd storey sala, being built at the moment.

I'm sure you're right, my plan was to put the radiant barrier stuff (foam with tin foil) under it - that works ok in the house so should be ok.

Do you have a link to those, as I'm thinking we'll do the back sometime too ?

They're just the same design as yours in the pic.... except white. Widely available .

Widely available... I take it you're not in Leyte

Foam with tinfoil insulation is absolutely sh!te, the heat destroys the foam in a very short period of time and it turns to dust, I think it is only available in 5mm or 10mm thicknesses any insulation material needs to be at least 50mm minimum to start to be effective, John if you can get to the existing foam on your roof check it out I'm sure by now it will be just dust, maybe it helped a little when first installed or you want to believe it did??? but now it will be Fecking useless.
Some of the Big hardware stores carry a decent plastic roof sheet in light colours this would be far better than any dark coloured Tin Sheet plus Foam, I would think it is 80% improvement on the heat transfer from a hot tin roof, even Cats can walk on it.

United red good man

I was referring to our Tubular or LGS in English...

Anyway, I don't need to get up there... I've only done half the ceiling so, much to my wife's annoyance, I can see it's ok and still working fine.

Ours has shiny stuff on both sides - perhaps that helps a little - doesn't stand up well to direct sunlight as I also use it to give the cctv stuff a bit of extra protection.

19:30 here and still showing 36 degrees in doors - lucky it's only like that for one month of the year...

I'm waiting for City Hardware to open here... taking them ages... soon hopefully.

City hardware? How many 115?

Yes, double sided foil helps, for a few extra peso get the double sided (shiny stuff) It will last a lot longer.

I never knew that @Jim, I got that one because I wasn't really sure what side up it should go

This foam insulation is absolutely Sh!te perhaps you want to believe it is doing some good after all, everybody else (Sheep?) is using it, at only 10mm thickness it offers little of any insulation and does turns to dust in a very short duration of time.

Now if I was faced with a problem having a CHB house with a hot tin roof, I would be looking at taking off the ridge capping, opening out a wider gap if required? to then re-install a wider ridge cap having it raised above the existing roof sheet to allow an unrestricted escape for the hot air, larger intake vents would be installed at the eaves equal to the increased air space created at the ridge top.

I would then install either mineral wool over the room ceilings or perhaps even rice hulls, 2inch of either should be fine.

Thanks Dave that sounds like very sensible advice

I was wondering is it feasible to use steel decking to create a raised living area?

Supported by concrete posts...

I was thinking I could join it to our existing house at or above ceiling level which is about 3 meters high so we'd have a space underneath and take our living area out of the flood zone...

Thanks Dave that sounds like very sensible advice

The vermin will love it.

Paint the roof white, (or have white panels fitted on any new roofing...as I've just had done) forget any fibrous/foam type of insulation, and yes, allow that improved ventilation at the ridge...as long as the rain can be kept out. JMHO.

I'm in process of having a room added, with an open area under it. Concrete construction, on 40 cm posts. Plan is to use the ground floor open area for drying clothes, when rainy, and just sitting out under. Roof panels are white-painted, with ventilation gap all round.

Of course an 'air-conned' building would need everything sealing off. I only use fans.

What is Vermin going to love about that?

John I am confused when you mention steel decking, do you meant there is a steel product that resembles wood decking? or do you mean the steel decking as used on the underside of concrete floors that act as both a strengthening member and shuttering to enable concrete to be laid on top, if this is what you mean there is no reason I can think of not to do this. Whatever you do mean Just remember any steel that is not GI requires constant maintenance especially there in PH, where a concrete deck can be tiled and keep its smart appearance for many years.

Thank you Dave.

I think it is this one:

" the steel decking as used on the underside of concrete floors that act as both a strengthening member and shuttering to enable concrete to be laid on top"

I was originally thinking the steel decking itself was enough to support a floor but when I looked on YouTube I saw they put concrete and rebar on top of it - 3-4 inches...

You can certainly construct a floor supported by steel purlins/beams. No problem.

Consider how the upper floor of most houses in the UK are constructed.

I would use 8' x 4' 3/4 inch ply for the flooring. Unlikely to be attacked by termites, so high up.
