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.

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.

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?

You never check before ask them come over?

Hope you did not pay them any deposit. The coolbatt things and similar are heavy so need wood or further strengthen your Plaster ceiling before putting it.

Put in support than ask them come over. Usually they have the contractor can help you, did you all them if they can provide.

Is not my job to check whether can install or not right

The salesperson came and check also didn't say anything. I didn't pay anything since no deposit required.

Now i am exploring TCL again.

Change it to TCL type. Solve.

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

I have few questions about TCL and hope the current TCL user can help me

1. After installed the TCL Cellulose Insulation, if any maintenance work need to do inside the roof, will the cellulose material raise up like dust? Will the Cellulose Particle drop down easily? Me and my wife have super sensitive nose and worry the particle will cause serious issue to our nose. Also worrying will causing asthma to new born baby.




2. If i will need to pull few more cable above ceiling, let say maybe alarm or CCTV, is the cellulose material can be adjusted easily? will it become solid and firm after sometime?

3. Last question is about water leak from roof. Since the Cellulose is all over the ceiling, how to notice if there is water leak from roof? Will cellulose material absorb the water until heavy and cause damage to the ceiling board?

Thanks in advance!!!
