can anybody tell me what is the official name for the system with the spinning things on top of your roof.
the one that are supposed to make your house less hot.
where to buy?
what's a good brand?
how much is the going rate for a normal intermediate double story house? (material + installation cost)

Turbine vents... those are the spinning type...

Or if you have the money you can install a fan driven ventilator...

edit:

As for brands I've come across mostly generic...

Here is a tip pick one with self lubricating bearings because after some time turbine might squeak and drive you nuts on windy nights...

The other thing is to make sure your place is fairly windy, if the air is mostly still then turbines don’t work at peak efficiency…

any idea on price?
need to budget.

Those ventilations create dust after installing . My house have those type too. It is now sealed completely because a few screws came off and the dust keep falling on to our furnitures.

Better look for other types of ventilations. Luckily I haven't seen any rats falling down from the hole as one of them is just right above my bed. Fuuh!!

Bunnyhoney, your room is directly below the roof tiles? There is no ceiling between the roof tiles and your room? Or is there any ducting?

Other types of ventilation I could think of are:-

1) Normal eletric wall mounted ventilation fan
2) Ventilation tiles

Any good suggestion on this? As I'm considering in place this to have free air flow in the house instread of eletric type.

Is DENKO brand good?

need some recommendation too, planning to get 2 on the roof since this new house pretty hot

how much it will take to do this?
sounds good.

several type exist..
1)residential/commercial/industrial
2) size-12"; 14" 16"

price for 14" residential about 160

it does really help?
Beside the dust and possible noise after sometimes... any other problems?

My place is quite windy, wonder how must the installation would cost.

TELL ME ABOUT YOUR ROOF DESIGN....

metaldec? tile? insulated? etc

160? Are you refer to the Ventilation fan like Kitchen / Toilet type or the Turbine vents type?

Bro Tiles.. red tiles...

http://www.google.com.my/imglanding?q=ALUM...iw=1007&bih=479

But the price is RM160???
I saw on market normally was RM700plus.

u kene sembelih already firned

maybe 160 for turbine only? 700 come with installation & material?

I like the design too. Noise level only 18dB on low speed!
Did you installed it?

not yet bro..need to wait for my electrical man to install for me
i bought it for rm 230
not sure is cheap or expensive
didnt survey the market for this fan
but if u happen to buy this fan
i got two extra switch to sell
cause i'm not using it....my fan will on when i turn on the downlight
so the switches..i can sell out

i think u need to install a proper sized brace to ur ceiling/roofing brace then only can affix the fan..

doubt think ur ceiling/pasterboard/abestosboard thing can take the 4kilo weight...

Is RM230 with ducting & outdoor wall unit?
This fan have 3 state - off, low, high - how you install with downlight switch?

i will run in high speed only..
the electrical man say can connect it..
for toilet
for room, not sure wanna use the switch or not
cause Low speed function can use when air con is turn on

ANy good recommending of brand on this?

I find this site quite informative for turbine vents

Seem Like Taika have good comments....what not sure about the price now, as previously it was 2 unit cost RM1100+

Sorry.. i think the talk about electric ventilation fan is out of topic, but i have curiosity on
how JinXXX install the fan by himself. As far as i know, you must make a hole in the wall first,
then, you can placed the fan.

JinXXX, you do poke a hole in your wall by yourself?

fyi mine is the ceiling mounted,

the ceiling is abestos board or something similar to that.. just use a saw to hack it..

FYI : its better to get a jigsaw to cut it... took me 20 to 30 mins for a hole..

Get a rotary drill, can make a hole easy on brick wall to install.

Is grill needed? Or, the other of asking the same quetion,
without grill, does it become an easy access for thief?

get the 8" fan, going in is hard not impossible. Maybe small size people can go in. Usually 8"ventilation fan don't put grill.

Is the Wesflo or Taiko brand better?

Just order the 2 unit of Denko Turbine Ventilator and will be install coming Saturday...
another item off from my list

how much bro for 2 unit?how many air vent?taika got promotion ka?tq

how much did they charge you for the 2 units ?

take some pics ya... and share with us

especially the bering and installation

This post has been edited by JinXXX: Aug 4 2011, 01:16 AM

RM 1250 for two unit.Max of discount could get from them.

Take picture during installation? Except if I was to clam up with them to roof top...

yr one is 16" 18" 22" ?? which size did you install.. ?

anyway if yr thinking of climbing and taking a special view of your roof top.. rmbr safety first

Is 16" Free Floating type (without Bearing)

I just installed it yesterday.. I installed 2 roof ventilators, 16", free floating type. It cost me rm648 each (the sales guy said, it's promotion price after rm200 discount.. but I believe everybody gets around this price).

My 2nd floor, even without the ventilator, it is not hot anyway because my house got airwell.. very high. I installed it so that the bedrooms are not hot during night, and I'm hoping it will be as cold as the outside night temperature.

After install it, I found that, IN THE MORNING, the room is still not as cold the outside. However, I no longer feel the trapped heat in the room like before. At noon, it's like i can work all day long, with all doors and windows open and without turning on the fan.. (bear in mind, even without vent, my 2nd floor is already not that hot due to airwell but I still need to turn on the fan).

Attic temperature : The different is like night and day. I used to go to attic to fix some wiring or check my water tank. Usually, after 5 minutes, I already sweat. But after installing this, it's no longer hot and it's bright in there as the sunlight can go in through the vent. However, this is not important. What important is the bedrooms' temperature below it.

Please note, each vent can cover 500 square feet area. I installed 2, so, they effectively covers 1000 square feet, and my roof area from my calculation based on the floor plan, is just 630 square feet. So, the vents are already optimum.

Overall, I'd say I feel the different. Maybe because the heat trapped on the ceiling has a way to go out. but it won't make the room cold.. as cold as the fan or aircond.


My suggestion, if you got money to renovate, first thing before putting ventilators or roof insulations.. make sure you build the airwell first. I rented a 2 story house before and got no airwell. I can't go up to the 2nd floor during the day at all..


Airwell (for those who don't know what is airwell) as seen from inside the house. Usually located above stairs or family room.

i think you just nailed the point.. the turbine ventilator is to remove the heat from the attic/roof thus reducing the radiant heat that can radiate down into the bedroom and etc

Done in place two unit of ventilation this morning, and take them less than 1 hour included removed off the roof alumimum foil and zink.
Unfortunated cant take picture as not visiable from front or backend as it blocked by my extention block...

Only picture taken are from inside to roof top

thanks for sharing, your roof is using metal sheets and not those cement/clay roof tiles ?

so how's the effect ? good ?

I have alumimum foil and Zink installed under the normal roof tile.

I not yet moving in hence not really could said improve or not.

oh okie...

cause from the pic.. i see the DISTANCE between the support beam like quite far, so thought it's not design for heavy load...

You saw is the main wood beam, those small one (1" x 2") are at other side of zink
Below is what actual done on my roof top before the ventilator

thansk for thre bro
only my room is hot and not the airwell
so if need also need to break teh attic area ...
XD

You can install ceiling ventilation to force outside air in. I will install 8" ventilation fan for all the 1st floor room.

why so many ppl install zinc at the roof top?

the insurance agent told me insurance company wont compensate in case of fire because the bomba people can't put out the fire because of the zinc sheet

What is the difference with clay / cement roof? water still can't go in. How about high rise building? no roof also.

your insurance agent told you that..

what does the POLICY from the INSURANCE company TELL YOU ???

My agent told me no problem. Unless you put fire hazard material.

aka self DIY thermal shield.. using bubble wrap and alu foils

Finally up to the roof to checked my roof leaking issues as the Indo contractor only free / available after Raya.
Hence able to take photo of my ventilator...

thats nice/good of you to share thanks alot..

what you mean check for leaking issues.. meaning its leaking ? or just saja check see ?

they installed it properly ? got any leak so far ?

Yah..my roof is leaking but not relevant to this...as the leaking at front end, and ventilator is on the back end part.

Here the link about the issus
http://forum.lowyat.net/topic/1842406/+60

How's the performance so far? Do you see any difference in the heat? Is it more bearable now without the fan or air-con.

anybody got installed or tried solar powered ventilators ?

eg like this http://www.scorigin.com/solar_fan__ventilation

Saw this on their website last week. However, the online sales is non existence.

Old thread...

Any users mind to share effectiveness of wind turbines for terrace houses?

good reference from panasonic:

yeap, how is the noise and dust issue so far? occurred?

For those already using the this for a long time, how is it? Any problems with the wind ventilators?

Does this work for low ceilings? Mine is like 7.5 feet from the bottom tiles to the top ceiling where the vent should be installed so not really sure if it would really 'suck out the hot air'

Can any share feedback on this air turbine ventilator? not sure is it really effective? How about solar ventilator? Pros n Cons both of this?

I still think the cfm from a couple 8" or 10" fans on the rooftop section (why not bigger = so thieves cannot pop in so easily if they can't fit their shoulders through the hole) at ~318/530cfm each will provide better active cooling effect. It does need a input vent (maybe toilet ceiling vent) for cold air input

So any good band reliable band ro reconmend for turbine ventilator nowdays?

just wondering whether its possible to install ceiling ventilation fans without the turbine ventilator? can we vent out thru the side roof instead or any other options?


asking due to MCO the shop is charging extra for installation..

I have ceiling ventilator fans in all the rooms and living hall on the 1st floor without a wind turbine. The purpose is to prevent heat built up from non air circulation.

Is better if there are wind turbines to extract the hot air. If depending on the gaps of side roof tiles, the heat exchange is slower.

Better to have preset timer to switch on the ventilator instead of waiting for the heat to built up.

thanks for the reply, so far does your 1st floor rooms feels less heaty?

for my current place it does not have any small living room, just a walkway from the stairs to the room on the upper floor, so everyday morning that area feels stuffy and heaty since all other rooms doors are closed so wanted to get rid of this issue..

dont waste money with these silly roof turbine fan. not only will there be leaking during thunderstorms after some time... the suction is so weak during day time...you cant feel any difference.

The best is to install a CEILING Ventilation FAN on the CEILING on the first floor. If your house has only ground floor then install on the ground floor ceiling.

this way HOT air can escape upwards and cool the whole house

Is better than b4 installation. I have a timer for all the fans which will switch on at certain preset time on rotation to prevent heat building up.

points noted but if no opening on the roof can the hot air escape via the roof tiles in time? or it may ended up as stale air in between the roof and the ceiling instead..
