H, just wondering how to solve this problem.
My room (most of the daylight) is facing the sun from sunrise to sunset.
This makes my room so hot like an oven. When entering the room, I can feel the heatwave on my skin.
Window is tinted with reflective tint, but still won't solve the problem as the wall and the window also very hot.

my idea is to install and awning. not sure if this will solve the problem.
aircon already installed but im trying to reduce electricity usage over here.

thank you

my teacher say, sun rises from the east and settles in the west. either your room can rotate or your room has east and west facing windows which is unusual. how about creating windows elsewhere?

u need something call a sun louvre

My opinion will be to double insulate everything

1. double glazing the window. film wont do the trick
double glazing means to have another layer of glass. sandwitching air in middle as insulator

2. double insulate the wall facing the sun (west side)
its not easy, but putting another wall (plaster one) should do the trick
otherwise think of putting bookshelf

3. reflective paint outside.

4. if you have a roof, consider rock wools as insulator

5. consider drop a false ceiling. again use air as insulator
and consider have air holes in the false ceiling facing west. this way hot air can flow out.
smaller room size also means easier on the aircond

6. these are true if its your own property. if not... move out.

my room is corner lot room, so the side wall also got heat up from the sunrise( black arrow).
when sunset got heat from front side (red arrow)
rough sketch

and also, i dont think sunrise and sunset do exactly 180degree. but that's not the point here

jinxxx idea is good too. but for residential maybe difficult as need to clean bird shit. commercial buildings got cleaning crew mah....

Good info. Learnt something new today. Thanks

thank you, will consider idea no1 for next project.

what do u mean by false ceiling??

i think the main contributor is the wall, it's bloody hot.

i tried to leave the door open, and the window open, for the whole day, still the same. in fact, all the dust from outside got trapped inside.
probably because my room is on the 2nd floor.

thnk you for the ideas guys

false ceiling means drop ceiling. like those u see in offices. of course can be made more beautiful la.

if u stay in the 2nd floor, means the heat is also from the roof. roof insulation can cut a few degrees C.

another trick i used last time. put table/stand fan and blow OUT of the window before u enter the room. this will encourage cool air to enter the room and the fan blow out the hot air. must ensure u have a source of cool air though.

in other countries, double glazing is mandatory by law.

The same for me. My room exactly facing sun during the day and feels like in a baking oven. At first cannot tahan but now I'm used to it. Kind of like my personal sauna room

I think false ceiling = plaster ceiling

I remember seeing those special paint where if applied, the surface won't become hot. Look for those for your external wall. I think that is the main culprit in your room's heat.
Then go for your roof, then air circulation.

Open up the windows a bit will help, it let the heat out. Just like car.

use blackout curtain can help?

only prolong the time for heat to come in, still hot. Maybe from 1 hour to 1.5 hours to heat the room. The heat is trap, it need some place to go out.

Also use a good quality tint, don't use the cheap tint, it don't have UV cut. Tint like 3M, V-cool can reduce the UV and Infra Red heat to the room.

If your room has such a layout where both sides also exposed to sunlight I don't think there's much you can do. You can put up tinted windows and curtains but the surface area of your walls and roof are so much greater.

On a sunny day your walls and roof will absorb heat and it reaches a point where it cannot absorb anymore so the head will radiate and therefore your room feels like an oven. And this is a reason why when ppl choose condo don't like to buy West facing units, house different because sure got 1 side kena sunlight.

It is better to treat your ceiling first where the heat comedown all day long. Use wool insulation, celoluse or whatever claim is better.

See how the temperature drop. Than proceed to window side to improve.

yeah.. i guess that's the minus point for this house.
other rooms are ok. just the master room LOL.

will consider that. thank you


right now. I just turn on the aircond, the lowest temp and lowest fan speed to prevent the heat.. huhuhu

cant help it, since living next to pelabuhan, the sea breeze really does bring the heat.

My kids room also facing a sun. At night, even turning on the fan at fast speed, it just spin the hot air around the room.

What I did was to install roof turbine. I reallyyyy helps a lot. It removes the heat from the room. So, by the time I got home after work, it no longer hot in the room. So, when turning on the fan, i can feel the different.. BUT, don't expect it to cool down coz roof turbine is for removing heat.. You still need fan or aircond..

Currently, the price is rm600-rm700 each, inclusive installation (i'm sure the price is around this, nationwide, inclusive installation)

I also bought a house facing west =.= looking for insulation solutions too, mayb at HomeDec fair. Any other modern solution on roof other than this turbine?

My parent house is sitting on West, we did not put this but instead put ceiling ventilation (KDK and Panasonic). It really help in the evening cause when you switch on the ventilation, it suck the fresh air from the windows, push out the hot are out from the roof.

I did that in my new house too, and added Zinc sheet on the roof. Now I don't feel hot on the first floor. Thanks to the zinc sheets.
