can try install a turbine ventilator..

to extract the heat out from the space between ur ceiling and roof

or install a ceiling ventilation fan to remove the warm air from the room and keep a circulation of air to keep the temp down..

air from bottom house raise up due to the ceiling ventilation fan and the air is extracted to the ceiling and the turbine ventilator take the hot air out from the attic/space between ceiling and roof...

u want better install thermal insulation material.. and if got some extra money to spend around wash and repaint the roof to white/silver shade..

economy way is turbine ventilators to be installed on roof top (around RM800) to cool down the heat, see below link

but for long term, to install air-cond would help, sure can kungfu abit.....

i think long term economy would be the turbine ventilator since it only cost installation cost

while for ac when u use it you have monthly bills hahahaha

i know not all turbine ventilators are built the same, any idea what are the good "types"

depends on what room temp you are looking for. in our kind of weather, the turbine ventilator will not lower the room temp much. Basically, its function is to draw out the hot air that are trap at the ceiling level. If the weather is hot, the room will not be much cooler then outside. Maybe a few deg C lower. That's all. This is from my experience from using them at my previous house

To really have a cool room, nothing beats having an air con switched on.  rclxms.gif Of course, there is the initial installation cost plus the monthly elect bill  biggrin.gif

well its better to get same temp inside and outside.. rather than hot inside..

previously my room was HOT... now its normal warm.. cause i've installed the ceiling fan,

but my hall is HOT cause there is no ceiling fan there, planning to install turbine ventilator so that the air in the roof can circulate this making it less hot.. this COOLER than the CURRENTLY HOT...

if you want ur room to be COLD/COOL then install aircond else, the best is to have equal temperature

for best result :-

1) install the aluminium foil e. monier radenshielf below the roof area.... involve removing the roof tiles... cost about RM3k for normal
    double storey house

2) install another layer of CSR Coolbatt above the ceiling area.. cost between RM2k-RM3k for 2 storey house

3) install tinted film...cost RM3k + for whole house...

4) put Nippon Solareflect paint on the outer area of your house...

guaranteed your house will be cooler !
*
sounds expensive lo bro...

i'm thinking of the nippon solareflect on my room, to give it a new coat since the old one is dirty and etc....

anybody used such roofing coating ? is it any good ?

my room + balcony is facing west , what is the best way to block the sunray to heat-up my wall & windows:

1. setup sun louvers at balcony
2. outdoor wooden blinds
3. outdoor curtain (with reflective surface, does it exist? )

1.. if you take aluminum it can last...
2... dont think can last long outdoors...

7. install those "extended" wall units.. like some office building they have another out layer of wall(made from alu) that has an air space between the alu walls and the brick walls...

no need repaint and the heat is stopped by the alu wall covers and the inner wall remains slightly cooler

Yes it is call bubble wrap. My company always buy in roll. It is fire hazard. You don't want so many thing that can cause fire or accelerate the fire in the room.
*
the reason that there is a fire rating is so that if there is a fire

the things on the roof/house is not an accelerator for the fire aka FUEL

FYI.. you might void your fire insurance if anything happen if that shit is in the bomba report.. man

Is it worth the savings to DIY your own combo of aluminium foil + bubble wrap, when it is such a fire hazard? I would've gotten fire tested radiant barriers that contains bubble wrap such as Heat Away or some other brands.

guess that can only be answered only when, a fire actually happens and you wan claim from insurance... smile.gif

Still is circulating warm air. Unless you have water to vaporized it.

sounds high tech water to vaporized ehehhe

the fan will still blow the same room punya "Warm" air around.. = no diff

we need to exhaust the warm/hot air out.. or prevent more heat/warmed from building up

= insulation or exhaust or aircond smile.gif

some buildings that encounter all-time heat even have special arrangement on the exterior walls in which plants are grown on the entire surface on the wall; but these methods are more common in other countries.

+1 .. there is a building in KL sentral that uses this...

need some kind of creeping plant/grass that is easy to maintain any ideas ?

guys, i just installed ventilation ceiling on today.. I could feel the hot air is reduced. Air flow better..
I'm think install one more ventilation window fan flow in the cool air from outside during night time.. any suggestion?

KIntos, why you need remote control?
*
one thing i dont like about ventilation fan ceiling/wall mounted..

is it helps with the circulation with also happen to increase the dust

I cannot understand. It is suck air from the room to roof, hot air will release on the top.
Added on June 19, 2012, 9:38 amAircon power consumption is much higher than ventilation fan la bro..
*
bro.. your air need to come from somewhere for it to be sucked to the top right

and that somewhere is usually windows/door thus dust will enter..

unless your hse is air tight.. and the only opening is installed with an dust filter.. smile.gif
