When your house is properly insulated there is no need for heat to "leave" your house at night, as it would be at comfortable temperature already during the day.

That is an awful lot easier said than done

For the last couple of weeks the ambient has been around 36 degrees and it is very difficult to keep that warm air out. I have implemented most of the main insulation methods but when I built the house I would have liked to have included double glazing but the budget did not stretch that far.

In a  high ambient it is virtually impossible to stop warm air from coming in through the doors and windows.

We have ceiling fans during the day and put the AC on in the evening to watch TV and in the bedroom at night.

my house had a serious heat issue even after installing foil backed insulation. Upstairs was unbearable and you would walk through a layer of heat as you came up the stairs.

After reading through posts on TV about reducing ambient inside temperature I used a multi pronged approach.

I installed 2 whirlybirds on the roof, 2 blower fans in the upstairs ceiling to suck hot air from the upstairs rooms into the roof cavity and increased outside roof ventilation to allow air into the roof cavity. Also used 3M film on the windows.

When asking for advice from the locals i got the usual "this is normal for thailand, people dont use upstairs in the day time." But I went in guns blazing and got it done after repeated pushing.

I originally had foil backed insulation only in the roof but daytime heat was still unbearable.

now the temperature of the upstairs level has dropped considerably. cost me about 20k all up.

Rainy season will be useful to prove everyone that whirlybirds dont leak (fingers crossed)

Where did you get these from? 

 

I'm also keen on some for my roof.

The whirly bird bases are painted in reflective white, which is what many folk in Australia do to their entire roofs..  It drastically reduces upper level temperatures.

I don't know if this paint is available in Thailand, but I'm sure someone knows.

BTW:  some folk think the Whirly Birds are electrically powered, as they spin so fast.  Not so - it's the hot air from the roof cavity escaping.

Roof paint is available at most any paint store or home improvement center in Thailand. I've used TOA roof paint on concrete projects with good results. I've seen other brands of light color roof paint at many shops in Buriram. 

I have a feeling that sola roof paint is not the same as standard roof paint:

It is, I used it. Available from all the usual places and every specialist paint shop.
