Gable vents are super common in Thailand. Yet there're hardly any vented ridges. The local builders have never heard of those. At least not on the residential roofs.

As relative to the thermal properties it provides? I'd say it's a bargain in reference to reduction of the cooling costs. PU doesn't de-laminate, the other "thin" stuff does and is mostly worthless in comparison. Edited March 31, 2022 by unheard Link to comment Share on other sites More sharing options...

I got a price for both and the panels shown with it applied at the factory was way more expensive, the thin stuff is fine and concentrate on thick fibreglass over the ceilings Link to comment Share on other sites More sharing options...

That's right since the ridge vents need to be designed and installed in a certain way as to prevent the wind driven rain water from getting blown into the ridge opening. There are numerous companies in Australia and the U.S. that sell properly designed ridge vent systems. There are none in Thailand that I'm aware of (not sure about the commercial buildings applications since it's a completely different market segment). If you decide to go with such an option here then it would definitely be some kind of a custom fabrication.

There are multiple roof metal forming shops spread all over the country. Many of those offer PU insulation. And just about every Bluescope affiliated shop offers PU insulation as an option.

The roof concrete tiles with soffits under the eves. I am assuming (hoping) we will get some ventilation as hot air leaks through the overlapping roof tiles........correct?

There is plenty of headroom for me being vertically indisposed as you might say. There are plenty of horizontal RC beams to walk along which allows easy access to the ceiling below without stepping on the panelling. I'm sure the ceiling would fall apart if I were to stand on it. I ran 2 x 4" steel beams welded togethr across all my wall tops so I cna traverse the roof space when building, can only do it during construction as they were 6 metres long 2 Link to comment Share on other sites More sharing options...

Same here. the nearest Bluescope store is close to a hundred kilometers away. The delivery charge wasn't cheap (even with a discount). They did sent their rep to check the site, to verify all dimensions, just prior to the order going into production. At least one of the local non-Bluescope metal forming shops also offer PU insulation but only sells Chinese (or Korean, not sure) roof metal, which is significantly cheaper in comparison.

I have two different roofs, with both types of insulation installed. Their thermal properties differ, a lot (I think - don't have any scientific evidence). The picture shows that yours is still in very good condition and probably will not de-laminate any time soon. But there are many visible cases of de-lamination out there. Don't know if it's related to the quality of the materials or environmental exposure, maybe both. Edited March 31, 2022 by unheard Link to comment Share on other sites More sharing options...

Encid Posted March 31, 2022 Author Share Posted March 31, 2022 (edited) The poles are buried 1.5m deep and today they are filling the holes for the poles with concrete, letting it cure overnight, then they will start running the cable tomorrow.

Encid Posted March 31, 2022 Author Share Posted March 31, 2022 BIL and SIL are most impressed. Passers-by were asking if we plan to build a resort or a factory... Both the land fill team and the electric poles team have been sleeping on-site overnight, in a small shelter on the family owned farm next door. My wife has been sending her brother cash amounts to ply them all with cold beer at the end of the day. No shower facilities - only washing in the pond, but they are all happy. video-1648632710.mp4 Link to comment Share on other sites More sharing options...

I think the only good option is to insulate your ceilings as to prevent heat transmission from the attic. Or the spray-on insulation, sprayed on the tiles from the underneath. As in addition to every other measure taken to keep your building as cool as possible. A perfectly insulated roof would still make no difference if the rest of the house is thermally leaky. e.g. walls, windows, doors and even floors could be all big sources of thermal energy entering the house.
