Why would you want insulation in a hot country like Thailand

[miked]

to keep the heat out.
have a white roof, plenty of vents. as the heat builds it will be pushed out through the vents as hot air rises. build two good quality bricks thick with a cavity. if you want insulate the cavity but no need.

MIKED
Exactly as you said no need for insulation, you agreed with me. So my question why do you need insulation still stands.

[Super Joe]

as mike says it keeps the heat out

normally for roofs here its thin aluminium foil type, fixed on the underside of the roof trusses with an air gap between foil and roof tile
quite cheap

walls some people go for cavity walls some the white 'superblocs'
.

[Super Joe]

So my question why do you need insulation still stands

to keep heat out
to reduce energy costs

Oxford english dictionary

Heat is not unpleasant
To prevent heat enetering you will be reflecting it. "white roof"
Insulation will retain heat as well as exclude
Why is insulation needed

lindosfan, If you dont have AC, I agree with you..a waste of money insulating. But roofing insulation will definately impact your electric bill if you are running an AC unit.

you should have gone to cambridge, much nicer place:

insulate (COVER)
verb [T]
to cover and surround something with a material or substance in order to stop heat, sound or electricity from escaping or entering:

I lived in the high desert for 20 years. With temps hitting 120 degrees Believe me insulation makes a big difference in keeping the house cool.

I would try the spray foam if it can be found here. Seems I saw some houses being built in the Pattaya area using that.

You can add a couple of vent fans in the attic to blow out the excess hot air. they can be set to go on automatically when it hits a certain temp.

If you copy on line from the cambridge dictionary, please copy the full meaning as I have now
From the cambridge dictionary
insulate (COVER) Show phonetics
verb [T]
to cover and surround something with a material or substance in order to stop heat, sound or electricity from escaping or entering:
You can insulate a house against heat loss by having the windows double-glazed.
AS PER ABOVE HEAT LOSS does not mentionkeeping heat out try the oxford the recognized version far better
Any way the subject is a lot of hot air

[Cowtown Comedy]

lindosfan, what is the point of your argument?? Its a substance used to reduce the amount of heat that passes through your roof....call it what ever you want.. when you come up with a new name for it please let us all know, and maybe let the material suppliers in HH know too.

complete waste of time....

[Super Joe]

lindos they give 1 no. example after each definition as a guide.
under 'insulation' their example is: "The animal's thick fur provides very good insulation against the arctic cold"
ever seen a polar bear wrapped in 6" rock wool?

Superjoe missed that one "entering"

[charlesh]

The heats got to me. I think I will have a big (insulated) fridge designed to keep the heat out and keep the cold in filled with bia Chang ha, ha.
Thanks for the input/output as my brain has gone into some sort of latent heat carnot cycle hiatus come meltdown.
