Not your job, but knowing in advance will help you decide and execute faster.

philipcs,

you can move them no problem. can also move back later. they form a uniform layer that can be broken anytime. just be slow and you dont create much dust. but for sure there will be dust. it stays in the roof though.

as for water: cellulose is paper. so go figure. same goes for any insulation. water would probably seep through to the bottom and then inside the ceiling rather quickly (its not a sponge lah). never tried it though, it's my assumption. you could ask TCL or ask for demonstration with a sample of the cellulose on top of a cut off board and then pour a glass of water on it. then you know. dont think they will mind - very friendly and accomodating ppl.

I was thinking of this but then found coolpu zinc roofing coz I need to change all my roof tiles too. The zinc on top already reflect sunlight. There is a form underneath that acts as anti thermal and anti -fire as well as noise absorption when raining. another zinc underneath the foam. I look at it as 3 in 1. Roof, anti-thermal and anti-theft.

some will say only factory or public places uses it but I was told by my contractor its popular now as bungalows uses it. Saw a few bungalows around my area have it as roof....

Car windscreen actually are made from aluminum film (metalised foil) which is actually made of plastic and it looks like silver in colour. In order to determine whether it is made from plastic or pure aluminum, you can use a lighter and burn the aluminum top and bottom portion. If it melts and the fire spread, it is actually made from plastic which is durable when you need to do repeated folding of the material.

PU Foam attached with metal roof actually can help you in sound reduction but if you are looking for something more on heat insulation, aluminum foil will still be the best option. This is because the PU foam tends to become powderise and drop down when the bottom supporting part give way. If you wish have a better longer lasting try use those which is bottom part made of steel instead of plastic. But whenever you choose to cut out the heat, you need to look at the product spec such as thermal resistance which is higher the better and thermal conductivity, the lower the better it perform.

Is there any DIY aluminum foil product in the market?

Yes. You can contact KFoil Insulation

My house car porch installed KFoil K640, single sided woven reflective insulation, it works excellent.

My house also installed with KFoil Reflective Insulation, Paper backed.

Reduced by 7ºC - Room Temperature or ceiling inner surface temperature or Roof inner surface temperature or...?

I don't think is the room temperature. Lets assume Malaysia average temperature during 12pm ~ 4pm is 32ºC, if room temperature reduced by 7ºC means the room temperature is 25ºC without air conditioning!

I believe that they must refer to the roof inner surface temperature not even ceiling inner surface temperature.

Anyone can roughly tell me how much amount if I want to put aluminium plate under my roof?

Maybe something like this

Want to avoid roof leaking and thief.

Bro 32 is d ambient temperature. The roof surface temperature might be higher. Bcoz heat absorption by air and roof tiles are different.

Hi.anyone can give me contact or website for heat away?can it be instaled if we alreadystaying in the house?

Exactky. That's not how to install the insulator.
