There are a couples of vent system to cool down your roof:




maybe you can ask your contractor about it.

thank you guys for the very useful advice.

LYN is awesome

oh, for ceiling if diy, just buy some rockwool insulation, or aluminium sheeti with those air inside.

lay/roll above the ceiling only. it really helps

Do you think that this type of wall would aid the heat insulation from outside?



I have the same problem too (the sun is baking my walls), and thinking to do 2 things:
- awning to keep my exterior walls cool
- install wall panels (looks nice too)

doubt that.. thats more for like asthetic.. doubt the materials they use are capable of blocking heat

better use the better tried and confirm matter to cut down the *sun baking on the wall*

Install fake wall (Plaster board) + black out curtain will be the cheapest solutions.

Roof do play a major part but not the key as most houses in M'sia also facing such problem with the roof.

After done your wall, you may feel the difference.

Your walls are too exposed to direct sun.
The walls get heated up during the day. The heat stored is radiated out at night.

You need to block off the direct sunlight by shielding the walls. You can consider:

1.  tree planting or creepers. These would take time to grow of course.
2. additional layer of wall with air cavity in between. The additional layer can be of weatherboard, metal sheet or louvres or bricks . A reflective foil in between would help to insulate the wall further.
3. Extending the roof cover or shade over the walls.
4. For windows, installing heat-reflective film like you do for cars would help a lot. The number of windows should be kept to a minimum.

With radiant heat from the walls, you'd feel it even with the air conditiioning is  switched on.
