Another option is to install solar panel to block the heat while generating electric. But initial cost will be higher.

What happen if roof tile broken and its raining?

It's reflective so it can reflect/insulate radiation

Not planning to replace the old tiles yet, so opt for smaller but effective enough jobscope.

Definitely coincidence, the heat getting unbearable in recent years.

hardwood batten?

your house is old one?

is this Radient Barrier by Monier?

Tensile strength also not bad

Also it secures your roof somewhat. Thiefs come in last time, remove the tiles and they are in. Now they have a foil to contend with and might just give up

TS is not my dupe.
He is my Believer.

LOL

PS: I found Sunfoil (https://yhlp.com.my/) kinda good. Shopee n Lazada got.

thx boss

these few days keep raining and cloudy.. of course "sejuk"...

Foil is waterproof but definitely not a replacement for tiles. If workmanship is tight enough will cause water to flow to edge of roof tiles.

Parent's house, pre-2000 😅. Not sure on exact brand, got catalogue on 1st page.

Yeap, too low will tear easily making it very messy during installation. This one cannot tear by hand and need scissors or knife, even then also need some effort.

Yeah landed house need to do this. Every landed house be it my parents bungalow, my in laws bungalow. 1st floor always very heaty during the day 🥵🥵

Even 1 of my new room tenant moved out from landed room rent to rent at my apartment. He say my god his room during the day like sauna so hot.

hi TS,
Where is your location for the contractor? I try to find in Ipoh and their charges for the labor start from 2K to 2.5K

He's from somewhere near Nilai.

I'm actually friend with the contractor, did a few jobs already for me before so I might be getting some preferred prices. My budget for labor is actually 1-1.5k tbh.

nope. this is biggest myth ever.

This not that so effective as the foil trap the hot air inside and gradually temp going up.

The most effective is to increase the ceiling insulation. This can be DIY easilly with rockwool.

put rockwool above the ceiling?

Yes. Once increase the ceiling radiated barrier, no heat radiates down to the room. And the roof above gets air circulated also.

i bought Tuya/SmartLife Wifi-based Zigbee-based AAA-battery temperature+moisture sensor, put between ceiling and roof.

It's not so much about accuracy, but in preparation to compare before and after installing ventilators on the roof. At least a measure to know how effective and whether I should install more ventilators afterwards.

A properly done layout would have insulating film > rockwool > channel frame > tiles/shingles, but I'm not planning to spend that much. Also hate rockwool fibres.

Bit too late for comparison 😅, but isn't it annoying though to have battery powered devices above your ceilings?

i open the ceiling hatches and just place nearby it, expecting needing to change battery from time to time.
at least for a few months while waiting for ventilator stock to appear.

i'm sorry. it's zigbee.
i check battery just now. both sensors' batteries still 100% since installed early June.
