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)

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.

Thanks man! I wonder who can do the installation for me or I have to DIY

I've had the cellulose insulation done by TCL and I've also had exhaust fans installed to suck cool air from outside into the bedrooms at night, and in the stairwell, to vent hot air out - a lot of hot air rises and used to get stuck there. I'm not the sort who would have the aircon on every day as a matter of course, but even then, both methods of heat control have enabled me to reduce my aircon use even more, quite significantly in fact.

Any contractor can do this job.... and you don have to do it.. the job is not hard but difficult in the sense that labour demanding that you need to climb, sustain ray from burning sun etc.

what roof are you using? concrete? metaldec?

a typical sandwich system is more than sufficient for insulation...

top layer- roof
2nd layer polywool fibreglass density=24kg/m^3
3rd layer- aluminium foil, reflectivity >95%
4th layer- S/S mesh to withheld the above(aluminium foil & fibre wool)

another factor also factor in.. air ventilation

Can this type be installed after the house is fully done up and renovated. Do you have to remove all the roof tiles to install this type of insulation?

Yes, it's possible, just more troublesome. They can climb into the roof cavity and staple the foil to the bottom of the roof trusses. Another option they will propose is laying the foil down flat on top of the ceiling, like how they do with cellulose insulation.

Anyone recent done any similar isolation? Mind to share the contact and cost?

Why not installing Galvanized Steel.

- Anti Theft
- Anti Heat

http://ezinearticles.com/?Galvanized-Metal...Know&id=1193788

I will be using some metal strip for my roof, not sure what exactly is it, it could be the Galvanized steel roll. My contractor told me is sufficient to block the heat and also help prevent thief coming in.

says who? a thief can open the metal fooring by looseining the screws..... anti heat? if no insulation(aluminium foil & fibrewool), then itll be as hot as sahara

i got quotation from Mr. Eugene Koh 012-6550757 heat shield... on Axis foil (manufactured by Axisjaya Ipoh)
for double sided aluminium foil, with bubble in the middle...RM2--80 per sq ft... but the foil is kind of thin..compared to the one i saw
at the recent mid valley reno expo... called Miron A+ insulation manufactured by M-PE Industry (Penang) ..RM3-20 per sq ft
contact Nicole Lee 019-557 1268/012-562 9031 Heat Shield Solution..

any experience on both products ?? cause I have yet to decide

if the gap between my ceiling and roof is only a few cm's apart, what is the best solution to use to reduce heat in the house? My concern is that my ceiling is not flat..its follows the roof steep incline.

Hope somebody can offer advise. TQ.

any idea which brand or company offer good value for money thermal insulation for the roof ?? looks like many company doing it...
monier, hong leong , axisjaya, M-PE Industry, etc...

Nothing can stop the thief to come in. It just slow them down. I got any idea from the Architect when I ask him for opinion. His house is using rebar (Reinforcing bar) on the roof. You know the thick steel mesh that contractor use for putting Reinforce Concrete. He put this on the wood that hold the clay roof. What he did is "Clay roof -> wood -> Rebar"

I was considering this option, but the cost is higher and need to do lots of reinforcing on the wood to stand the weight of the roof and medium thick Rebar.

IF anyone is rebuilding a house, this is also one good option to slow down the thief entering your house.

I'm plan to ask ground of Indo to lay the zink + aluminium foil, any hint how the measurement should be calculate so that I could buy the material from the hardware shop.

Once completed do mind to provide the contact and quotation because i am planning to find ppl to do it. I got a quaotation from Heat away for rm 8.50 per sqft .

So my house about 22x75 ( Roof surface estimated about 1000 sqft) cost about RM 8500

Almost similar to when I asked those folks at the house road show. Crazy.
Estimated roof are around 1100 sf, hence meterial it self will cost me not more than 2K depend of what type of aluminium foil I get.

that no quotation at all, you just need to estimate around 3 days work x daily labour for the Indo x number of Indo. my estimation with be 3 Days x RM 100 X 3 Indo = RM900 or 100.

I am planning to get the cheapest range of Monier RadianShield Met...RM200 per roll..which is available at most
hardware shops, too bad they don't carry the more expensive range !

try bubble series.....

Today one of my contractor highlighted this to me, but from this treat I didn't see the outcome whether it do void the insurance.

The main question is "If lay Zink sheet under the roof tile, will this again insurance policy?"

http://forum.lowyat.net/topic/525358

already installed the radenshield woven met..the house become cooler...now i am thinking to put the
CSR coolbatt RM3-20 per sq ft ..above the ceiling...to make it even cooler....

how many layer you plan to put lah?

Added on June 19, 2011, 12:32 amJust got a quotation from a Indo for remove and retile the roof with Zink and aluminium, as he asking for RM2,700 only LABOUR cost. Material on me.

It seem like on high side, any comments or still consider cheap?
* My roof estimate was 22 x (75-30)...


This post has been edited by Jo_da48: Jun 19 2011, 12:32 AM

$200 per roll is cheap, i was quoted $400 per roll! is it double sided?

Just wonder how about putting those office ceiling board under the roof. Will that help as an additional layer of heat shield ?

btw, what's the measurement per roll for Monier Radiant Barrier ?

This post has been edited by firestream: Jun 24 2011, 12:49 PM

was quoted Radenshield Woven AL $400 , 1.25 X 48m per roll.

Hi all,

Does anyone have experienced using Heat-Away Radian Barrier Reflector? There is a company quoting at RM 2.20 per SQFT for supply and installation.

what brand?

I thought Heat Away Radiant Barrier Reflector is the brand.

My roof work with start tomorrow by Indo with price of RM2K,

Material on my
1) Zink code: 30
2) Aluminium foil
http://www.foil-laminate.com/products_serveces_mf2.htm
3) Wood (2" x 2") in case old one broken, else will be use to close those gaps between it...
4) etc

So far about material already cost RM 1600.
GUess it shoud reduce income heat plus secure my roof top too...

Finally the roof done with Zink and Aluminium foil. Now wait for a heavy rain to check whether any leaking or not before in place plaster ceiling

Some photo share with you...

External view





Internal view

All these different types of insulation, I see the thin aluminium foil type and the thick wolly type.
Do they all need to follow the roof gradient (more meterage) or can they be laid flat above the ceiling (less meterage)
Which type cheaper ?!?

On the roof type for sure the most expensive, as they need to take out the roof tiles / wood out from there if want proper way lol, and labour cost for Indo is around 2K (at least on my case), which take them almost 5 days. But you may able to get cheaper.

As for aluminium foil depend on quality than you purchase...

it depends how you designed the flow of air.

A ceiling with vent hole reduce heat build up during night.
So there is a cross breeze build between roof; so that hot air will flow out.

those are the minor things. Couldnt understand why the minor much an issue for you.
It can be prevented.

A very simple design of understand inner air drive out.

hi - my friend used it - it really is cost-effective - definitely worth doing - i am about to also - please see: http://www.cooltek.org/. best to use DOUBLE sided foil.
do not use insulation bulk material - not suitable for tropics - reflective foil most suitable.

hi huys, anyone use monier radiant barrier? is anyone know where can get it in klang?

coolbatt maybe a good product ... but their installer has no idea of how insulation work... t

I don't prefer this type of instillation. First heat still trap between the roof and ceiling, second when you want to do wiring work got to dig out the insulation.

Besides Coolbatt and TCL, what other brand/company available in Klang Valley doing Thermal Heat Insulation?

I am not DIY guy and i prefer a company do this job with warranty provided.

Thanks.

i think TCL is the only one for cellulose unless someone else is doing it now too. they are pretty good. if you can afford it i suggest you do both - cellulose insulation for the ceiling and coolbat or similar foil for the roof. in combination you'll have a great reduction of heat for the house. i did it and this allows me to AC the entire house for around 0,15 KWh per month and sqft.

Can cellulose be put in between concrete and plaster ceiling space?

Do you know roughly how much for 1000sqf?

ozak,

since its blown into the space to form a uniform layer i'd say most likely yes. but it will depend on the actual layout of the space in question. you could check with TCL and request a site visit.

philipcs,

i think i paid somewhere around 2,XX per sqft for the cellulose. the foil i bought from a hardware store and got installed when my contractor took down the roof and reenforced trusses etc. so i got the installation FOC. if the roof is in place you can most likely install it from inside the roof but you might have a hard time to cover the entire roof properly. the trick is basically to cover all the way because then you create a barrier for the hot air and when you have openings at both sides the natural draft (and whatever wind you may have) will help to continously carry out hot air before it gets into you actual roof. so the cellulose has less heat to shield of. also you should not cover the cellulose so air can circulate and transport heat (and moisture - beware of the dew point!) away.

Guys, my ceiling area is 20ft X 25ft. Wouldnt mind DIY if its cost efficient.

Any recommendations?

thanks!

Alternatif material is foam sheet. Get the thick 1 and DIY ontop the ceiling. Effective too but not as good as those commercial 1.

i think coolbatt and TCL installation is almost the same...


Attached thumbnail(s)

TCL is better in my view... b'cos Coolbatt is difficult to install.... like the photo...



Attached thumbnail(s)

I'm confuse also...but the photos below are from TCL website...and the installation is much more difficult inclusing removing rooftop.


Attached thumbnail(s)

Who care it is difficult or easy to instal. All this done by the installer.

The important for us is which 1 is the best for the money and the heat resistance.

I'm agree with you
both brand have pro and cons

TCL end result is better.... Coolbatt only effective on a empty ceiling... the one without electrical wire or water pipe running here and there...

The earlier photo is my house actually... no effect at all... waste of money

I am considering taking it out...

i see...i saw monier also not bad...but my concern is they will install under the rooftop, how do I go out to rooftop in the future to fix something? any1 using monier radient barrier?

I thought Monier's Radiant Barrier is usually installed following the gradient of your roof, either above your roof truss or just underneath it. So you can still go inside your roof cavity through the manhole at the ceiling. If there's something wrong with the roof tiles, you would fix it outside of your roof. The barrier won't get in the way.

Is actually nightmare for pipe and electrical maintenance. Also for house owner using light bulbs with ballast. And if house pipe or roof got leaking, can growth mushroom :-) .

I ask similar vendor before of the points above. Can never give me satisfied answer.

weikee,

actually - you can easily move the cellulose to access any pipes you might need to. just put the flakes back afterwards. been there done that. it's a bit messy but not a huge issue. it does help if you know where to look for the cables and such. if your electriction (or plumber) did a proper layout to beginn with it's not much of a hassle.

ballasts are a problem - if their under the insulation they can get too hot and will blow.

if you have a leakage your ceiling also will have issues. the cellulose should however not get moldy cause it *should* be treated. the one from TCL is. some el-cheapo flakes from china might just not be properly done. afterall even though you essentially place old newspaper in the roof it's not that simple

Water leak without the insulator will be able to spot earlier. With the insulator the water will absorb into larger area, and may risk ceiling going collapse especially for plaster ceiling. Cleaning up the mess of absorb water maybe challenging.

I do see some benefit, it absorb the pump sound.

Yes cellulose can put on any surface and application

---

Added on May 24, 2012, 2:42 pmthe light bulb and ballasts problem, from my opinion there will be a protection to let the heat out if not it will be like what u said the bulb will blow.
we have did several houses and with all the nice covering and our cellulose is from AUS and USA

Us, au, even japan have code to follow and they enforcer it very tight. You should see their workmanship especially japan. I handled my previous company tokyo office relocation. I can you, their new complete empty office block before renovation is near perfect, the floor, roof, finishing is dam perfect. Even much better than our contractor here after renovation.

over here as long can work is ok.

if you dont create a seamless cover of cellulose you will create heat-spots and if your house is a/c-ed 24/7 there would be a risk of dew points between the cellulose and the ceiling (aka asking for mold growth) right? at least my calculations for the insulation and my real-life readings indicate that the dew point is a thing easily overlooked but lurking across anyone head who is insulating the house in malaysia.

yup i agree with u, that how good japan is but i also believe that some contractor in malaysia they will do a good finishing too because if a good finishing is done it simply mean that there is a good service rite? on the other side if i renovate my house/ office i also wan to have a so call prefect finishing.

All the option presented here seemd to take a lot of work. What about the whirlybird thingy (the spinning mushroom) option.
Is it good for residential house?

I may likely put in the poured in foam type above the ceiling like picture posted earlier with a hose from lorry to ceiling.

I agree with the guy who explain to me that putting barrier on the roof is not sufficient for a terrace house. Hot air will come in thru both your neighbour roof and then enter your roof from the sides. Most terrace are not fully covered at the side partition with neighbours. Make sense to me.

It helps, a little. Doesn't do much to stop radiant heat, which is primary cause of heat in a house here. Also, if you turn on airconditioning at night, and wind is blowing, cold air will get sucked out from your room.

Added on May 25, 2012, 11:51 amActually, MOST terrace house should come with this side partition, known as the firewall. It helps prevent fire from spreading.

That's what I thought, maybe should also be known as anti burglar wall.
So a burglar cannot accces one terrace house and have free rein of whole block.

Regards

well my roof is now "gone" and I can see gaps between the partition and the roof of my neighbours. Guess that is what he meant when the hot air from neighbours seep to under your roof.

Ask your contractor build up the wall. Is your house old house? Only the 49ers house use that, maybe summer in 80s

Very old Hse. Yup it will be a wall as I m adding half floor.

Hi, I just met a guy from local company who manufacture heat shield - Xinfrax

The price is RM2.4 per sqf and the installation is behind the Roof, not like TCL or CoolBatts sit on top of ceiling.

This is the demo.

this is the temp. read of Normal aluminium foil


this is the temp. read of their product


this is the temp. read of standard roof zinc


this is the temp. read of their product on top of the roof zinc



Here is their material, kind of thin.




This is inside view, it doesnt use glue so will no have peel off issue in future.


Any thought of this product?

Looks similar to Heat-Away. Double sided alu foil with bubble wrap in the middle.

Do you (or anyone) know the heat-away as effective as compare coolbatts and TCL?

RM2.4 per sqf quite low compare to the later.

I use Heat-Away. I think they are all effective in their own ways. Heat-Away sits on top or just underneath the roof truss, while CoolBatts and TCL sits on top of your ceiling board. CoolBatts/TCL would be better if you constantly aircondition your house, as it thermally insulates the ceiling board too. Use both types for maximum effectiveness

My worry with Coolbatts and TCL is how do we know if there is water leaking on the roof?
Will the TCL Material or Coolbatts absorb the water and increase weight? If it does, will the ceiling board corrupts due to too heavy after absorbed all the leaked water?

Yes, my shop sell this too.
Some are stick to the metal sheet.
It can reduce heat and many have tried.
Not sure is it 7 degree that much but definitely can feel the different with or without it.
Some paint also can reduce heat by 5 degree.

Dear all, i actually have shortlisted Coolbatts for my house heat insulation solution. When the installer came last wednesday, they said my house cannot be installed. The reason is because my upstairs ceiling are all Plaster Ceiling and no wood plank at all. Therefore the installer has no area to step on to lay the coolbatts. So sad

Anyone done heat insulation with this kind of new houses?
