I always know higher floor is hotter... Thus I got myself 3 storey where I only use 2 storey... The 3rd floor is used for store room and guess room that hardly use... 3rd floor mainly help the vendilation...

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...
3.. never heard of such thign..

4. Solarreflect nippon paint..
5. tinted window
6. ventilator fan

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

polisterine on the roof

logically it helps.
if it could keep out the heat from melting the things inside, it should keep the heat from going down to your room as well. Keyword = "LOGICALLY"

installing an air con could solve the problem but that is not an option to you since you stated so. ALSO if air con is installed, overtime it doom us all. short term solution with long term effect. WAKE UP people!

I had that problem at my old house too. the source of the heat is from the window facing north the sun shines from morning till evening. i kept the curtain close halt and open that window to allow ventilation. I also kept my door open.

but since this is your media room with no aircon, i would suggest reposition your electrical things that generates heats away from easily heat trap area. (ie corner with no immediate window) and install a ventilator. one off cost with no electrical commitment. try using old newspaper as a replacement to try out polisterine during the weekend. means you have to use install it on saturday morning till sunday but quickly replace/remove after you have the results. Remove or replace with polisterine if it helps a lot. I dont know if polisterine is highly flamable, but if it is then dont use that as well. you can try aluminum foil (Shiny way facing up) as an alternative. two side of aluminum foil, 1 transfer heat to the other side and 1 reflect heat. The shiny part is the one reflecting heat.

thz jinxxx & zeese for the proposals , could not afford to implement all the solutions tho' , i suppose option 1 or 2 would hv the best cooling effect among all rite ?

btw , is water spraying fan harmful to us in long run ? not spraying directly to the body of course ... any complication ? mold problem ?

Removed since commented caused Fire Hazard

Any fire hazard concerns using the bubble wrap (pop pop plaster)?

This is in between the Concreate roof and Plaster ceiling, and if fire hazard it will start from room as fire can't go thro concreate, right?
If in the room, everything in the room are the possiable of fire hazard already...only thing I could imaging will be the heat or wire from downlight as it will be the only item on the plaster ceiling.

* It called "bubble wrap"? (pop pop plaster)

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...

Only thing that could really prevent "fire hazard" is stay in a Metal and no electric good house....
Wood, curtain, electric good, light all are "Fire Hazard" free?

It all depend ....

This is where I plan to put...

Just use Solar Window Film. Heat Reject up to 80%!
Interested please look for me. =)

that's bro...
i also wanna a turbine ventilation for my home

It's what I'm currently doing, using the top floor for storage purpose and laundry hang drying. The 3rd floor which is also the top floor only consist of masterbedroom, but due to the temperature during daytime is too high, it's not an idea place to make it a bedroom since I'm currently renting and no air conditioner is installed.

awning?

how about upgrading the 3-blade fan to 5-blade fan?its cheaper,and i believe 5-blade fan give more cooling air.
