there are few options for insulation...

1) wool or fibreglass wool...
2) aluminium foil to reflect heat radiant( this range from Rm 60.00 per roll to Rm 500.00per roll, depends on its efficiency highest is > 96% reflectivity)
3) or Astino PU insulated metal roofing

1) in long run, the wool might wall down as it is supported by hex chicken netting which will rust and deterioate in time....

2) this type is metal roofing or metaldec
it is know as Gauge thickness
G 32 (which is the thinnest.. for wall application)
G 30 (typical application)
G28 ( higher standard)
G27 ( normally rich people and use)
G 26 ( thickest... bloody rich people, government and factory use)

NB price differs again for step roofing.. which is about Rm0.50 more exp compared to long run

price is dependents on Foot Run basis... typical G30 would cost about RM 3.50 per FR while G26 would cost about Rm 5.50 per FR

say your house is 20' long and 30' wide

so its (20ft x Rm 3.50 x 12pcs) = RM 840.00 for metal roofing only

but the corrugated is the cheapest of all.... abotu Rm 1.90 per FR which can easily rust in a year time

I've got a question about cellulose insulation. After the thing has been blown in the loft, what happens when I need to get up there to fix the wiring or to do what ever? Will I get cellulose fibres pouring down on me when I remove the ceiling hatch to get up? Will I have fibres sticking all over my clothes, my hair etc etc?

96% reflex. for rm500 per roll is cheap.
i got PARSEC termo B III for my parent's house, rm 1700/ per roll of 96M

I engaged the service of TCl Resources too last Friday for my small apartment. I'm happy to say that it does bring down temperature, and the people from TCl are very professional like you said.

for others, don't expect your house temperature to go down until very cold la. that is NOT the purpose of roof insulation.

oh TCL done my house liao. Not bad the result.

i see. yes, if not expect cool like refrigerator, the result is quite good. what i dun understand is why there's a research by local university saying roof insulation does not work in Malaysia. Really rubbish work. Somemore publish on Internet. Those who think roof insulation work for them should go share their experience there ---> http://www.scribd.com/doc/13455204/THERMAL...ROPICAL-CLIMATE

. It's environmentally friend thingy. Don't let these irresponsible, cincai study ruin these green efforts. Kajian tempatan.... *sigh*

Aiya, no need to waste time with these people. The first named author is from MARA. Celup punya.

Memang celup .... sigh...

i read it just now. i really wonder what they measured. i have before and after readings (TCL cellulose) and my results match the ones of you guys. using them is free cause you save so much on a/c charges you break even after a short while and then you have the savings in your pocket personally i would assume that insulating the ceiling alone will shave off approx. 20-30% of the bill based on my previous experience ina single story link house.

May be someone should advise them to carry out the test again to houses installed with TCL cellulose.

The report will be a laughing stock if present in international conference.

Maybe they were funded by some company with a rival technology lah.

Anyone knows the latest price below?

this type is metal roofing or metaldec
it is know as Gauge thickness
G 32 (which is the thinnest.. for wall application)
G 30 (typical application)
G28 ( higher standard)
G27 ( normally rich people and use)
G 26 ( thickest... bloody rich people, government and factory use)

can i do both insulation (cellulose) and the roof security system, which one comes first? also, i want to change the whole roof tiles as i just owned an old house, i would like to know what comes first?

i'm sorry, my first time, no experience in this kinda thing..

appreciate also if anyone can help me on new roofing..price per sq.ft

TCL did the cellulose thingy and added metal battens to my rafters (the security thingy). Two days worth of work. I suppose they can change the tiles for you as well.

Hi PangurBan
thanks!

How much does it costs you for both?

RM4900. I think it was RM3000 for the cellulose and RM1900 for the battens. It depends on the area. Mine's a 20x70 extended fully to the back alley.

Will it grow fungus inside?

well any price increase latest issue?heard material building increase 20%!!!

Wah! goodlah if can. I can have my very own mushroom farm up in my loft!

dopp,

you mean the cellulose? nope - cellulose actively regulates the moisture and channels it out so unlike with other insulation products that might create a dewpoint and corresponding moisture issues this will not be the case with open cellulose. no need to put anything on top either just blow and the cellulose does its thing. in comparison to the stone-fibre wool we had placed in the previous house, the cellulose wins hand-down.
