Just a hint for anyone going same way with insulation, use LED lights - no heat, low power and readily available on ebay from China. Power savings great too!

I will soon be getting roof insulation in my roof space to reduce the unbearable heat in the upper rooms. I already have silver foil under the tiles however this is not sufficient. To supplement this I am also considering some additional upgrades.

1. Roof extractor - Has anyone seen or considered the following solar powered roof extractor in lieu of a whirly bird roof extractor http://www.solarwhiz.com.au/solar-whiz-products/
2. Installing heat reflecting window film to windows on the west side, I have tried the commercial stuff from HomePro and find it useless.
3. Installing window awnings, only problem is access for the upper floor.

My first suggestion might be a problem since you have that useless foil that eventually tears and I don't know what it accomplishes. Try sprayfoam under the roof tiles. That will knock the heat down upstairs and seal the roof so it will never leak. A bit less costly is putting insulation in the attic over the ceiling. That will keep the heat from coming down from the roof and into the room. Any of those two should knock the heat down a good deal. Of course tinting the windows on the afternoon sun side should help a bit and can be done by replacing the glass or getting someone to install the film on the inside of the windows. You can shade the windows from the inside also by installing blinds.

Have fun.

Just to make sure I was taking the right approach I took some temperature measurements today
1. Outside ambient in shade with no wind 31C
2. Inside downstairs living room no A/C or Fan 29C (some shade to this room)
3. Upstairs bedroom, curtains closed no A/C or Fan 31 C (no shade to this room) I would imagine temperature would increase as the afternoon progresses with more direct sun om this room.
4. Roof space with silver foil bellow tiles 34C
So now I question the value of spending 100k+ Baht on roof insulation being worthwhile?

It is a good idea to vent the roof space. Not sure about the solar fans, but the "wirly bird" type are both a bit of an eyesore, and can become noisy very quickly. If you have suitable gable ends on the roof it will help a lot if they are fitted with some static type of vent, provided that they are vermin proof.

I have done a few houses over the years and I always use a double layer of the "batt" type of insulation, laid 90 degrees to each other.
As mentioned earlier on this thread, be aware of keeping the insulation away from downlights, if you have them.
