Anyone use this heat-away thermal shield before to reduce the temperature of the house? It claims it can reduced by 7 degress celcius. Is that true? The material looks like car wind screen shield but maybe different materials..

Any experience please share...

I think is something like bubble foam wrap.

yes, saw some bungalows putting it. but never feel it before.

i put mine on the porch to replaces the asbestos top..........during the heat of the day, same as under a concrete..dont feel the heat at all but mine is made with the metal sheet. as for my parents house, the used this as insulation and the room temperature is down a lot. previously i sweat whenever i slept but now, no more.

The heat insulation sheet you're referring to look somewhat like this


I installed the whole roof of my house during my recent house renovation. I must say that my house is alot cooler as compare to last time. I am able to save up on my air-condition by using the fan instead.

is this similar to cellulose insulation (by TCL?)

hi night...

i observed few types..some are what you show on the picture...but the heat-away one is very thin...just like the car wind screen shield...but they demo to me that it's able to block infra-red.....

I'm using those alumine type on my existing house, it does cool down but noticed heat is there because of without airflow...(just like without wind at home).

Looking at the product, is can easily DIY since it just lay on the roof floor instead of roof top itself

WHat the cost like?

it is known as

1) aluminium foil (laymen term)
2) radient shield/barrier(technical term)

basically, there`re few grades... by reelctivity... how many % of radient ray are being reflected

1) made in china one.. normally reflectivity +-50%
2) better grade... >97% Brands available in market... DuoFoil, Monier, camel etc....

both item 1 & 2 available in
single layer like one way road

double layer.. two way non entry

and some even manufactured with build in bubble....

the reason.....
1) increase surface area
2) form another heat conductive insulator(air)

Added on April 23, 2011, 6:18 pmit is a sandwich insulation system...

another leftout layer is poly fiberglass wool... the yellow coloured cotton lookalike(becareful) it will cut your hand...

this is a good thermal insulation(conductive & convective wise)

i'll recommend Parsec thermo-brite III

how much it cost for parsec thermo-brite III? thanks

not sure about latest price, but i bot it 3-4 years ago @ 1.3k+

I dont think the price is justified...

Duofoil double layer(non fire retarded-about >97% reflectivity) is about RM 300 ++ per roll.. 1.2m x 45m

monier radent shield bubble about 400-500..... per roll

don't compare it with those paper base alum foil lar

ya parsec thermo-brite III is very expensive, cos its imported mar..

the size 1s 1.2m x 97m if not mistaken

Where to get the duofoil or monier radent? Any contact or website?

I'm using Heat-Away. http://www.gpgmt.com/solutions.htm
Can't recall exact price, I remember it was pretty expensive, per roll. RM 600 maybe?

I wouldn't say you will notice a 7C drop in temperature. It's more towards preventing your ambient temperature from increasing too much due to the sun's ray. I have climbed above the ceiling into the roof cavity during mid-day ( during my Unifi installation ), it doesn't feel that hot inside. Usually, without a thermal shield it would be incredibly hot like a sauna.

It won't magically cool your house, if that's what you expect. It would, however, make your aircond work less, hence save you money. If you use an IR thermometer and measure the temperature of your ceiling during midday, you will probably get temperature of about 30C, whereas without any thermal shield, it's probably 40C or so.

I'm living in a 3 storey house and I do notice that the 3rd storey is way hotter than the rooms in 2nd storey and the living room which suggest that the roof is badly insulated. How do these insulation materials deal with downlights that protudes out of the roof ceiling area. Do they cover the whole thing?

radent shield by Monier... can get from any hardware shop selling monier tiles...
http://www.monier.com.my/products-services...nt-barrier.html

DuoFoil by HongLeong Industry. Also by any hardware shop
http://www.hlm.com.my/Duofoil.html

N.B dont even call the number on the web to buy.. unless you are goin to buy >100 roll from them.....

p/s insulation roof come in a system... not a single product.... so, you can use a super duper radient barrier but not efficient system/installation wont show how effective the super duper product is...

it is like attach a F1 tyre onto a kancil...

Foil type of thermal insulation is usually installed between roof truss and batten. It follows the gradient of the roof, hence does not sit on top of the ceiling. Other insulations may sit on top of the ceiling. Usually they cut holes where the downlights protrude.
