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.

i was told they would create a removable "pillow", so u can open the ceiling hatch without problem. the wiring... they explained to me but i no contractor so i can't answer. the best is ask them directlyask them directly. no harm ma.

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*

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.

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

Hi PangurBan
thanks!

How much does it costs you for both?

Will it grow fungus inside?
