Hi all,
I want to install heat insulator and zinc sheet on the roof for security purpose.
I was quoted as below:
"The length of your house should be 50 feet because the standard set back is 20 feet.
I presumed the length of your 1st floor is about 47 feet.
Ceiling area is approximately 940FS
Therefore, roof area is 20'x51'x1.12 (extra 4 feet for roof eave and extra 12% for gradient length) = 1140FS
The thermal insulation (cellulose) system is RM3,208.00 and roof security system (using zinc sheet only) is RM3,734.00"
That would be RM2.81psf for the cellulose insulation and RM3.28psf for zinc sheet.
Would it be expensive?
Currently I was also offered RM2.60psf for rockwool insulation.

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

Would appreciate any feedback from you all on the:
1. pros & cons of rockwool vs cellulose,
2. the pricing on zinc sheet. <-- does it have different grade?

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

put grill for another 2'. For the roof, some people advise not to use the Ajiya Awning because it will be hot and noisy during raining day. Alternative to reduce noise some contractor suggest using polycarbonate skyline (compact type). Anyhow, it will be hot too.
Another contractor told me to use industrial zinc roofing with added fiber glass & reduce heating layer. Where can I find this product? Any suggestion for contractor that doing this?
Appreciate your kind advice.
Thanks a lot.
to be frank, any metal roofing will be noisy if rain falls.... Another contractor told me to use industrial zinc roofing with added fiber glass & reduce heating layer. Where can I find this product? Any suggestion for contractor that doing this?
