Dear Boss Ozak,

I total respect you and your comment
8 Star Leader & Senior member.

Am Guessing that you had a bad experience with Polycarbonate, in which may happen to other people too

Unlike you, I dislike the Contractor more than the material.
Material I can do my own research and select the Best in the market.
Contractor aim is to sweet talk you and close the " Hit n Run " Business.

I replace my old Water Heater with Panasonic Top of the Range & Expensive Model.
After my research, I found out that Panasonic use PA66, which is High Temperature Resistant Plastic anf would never break for the Heating Chamber.
Therefore, I probably won't die of Electrical Execution during my naked shower.
We heard many case where people die in the shower.

Manufacturers and Contractors are very similar . They find you the Cheapest Material and lower the price every single year. But They Never lower their Salary Every Single Year.
However, Japanese MNC , until today never ignore safety in their products they are making
In my Opinion, they still make the safest appliances and energy Saving.

I use Lexan 2 Walls for my awning and it's been 6 years. There is no problem, no yellowing, no algae, no water and no dust in the awning.
I paid high price for the material but unfortunately, the Contractor that Installed it sucks.

There is also 7 Walls and 9 Walls Polycarbonate for awning too. Not sure if Malaysia have this
There is 15 mm Solid Polycarbonate too costly for me

Cheers Bro

got le.. go update with new products.

just some examples below

LEXAN™ THERMOCLEAR™ Sheet 5X Structure 16-32 mm Sheet Datasheet Americas, Asia Pacific, EMEA
LEXAN™ THERMOCLEAR™ Sheet 9X Structure 16-25 mm Sheet Datasheet Americas, Asia Pacific, EMEA
LEXAN™ THERMOCLEAR™ Sheet 9X Structure 40-55 mm Sheet Datasheet Americas, Asia Pacific, EMEA

just youtube this topic, should get many ideas for awning/carport usages
Multiwall Polycarbonate Sheet

Ozak,

We should make a check list

Manufacturer

1) Warranty the Roof Don't Change Color or Yellowing
2) Warranty the Roof Does not Break
3) Warranty the Roof Does not become Blurr
4) Safe Plastics, not cheap, recycle or toxic plastics, they Called is ROHS Compliance
5) Low Heat Transfer type

Contractor

1) Warranty on their Workmanship ( The Longer the Better)
2) Guaranty No Creaking Sound
3) Guaranty No Waviness
4) Guaranty No Algae, No Water, No Dirt and No Dust
5) Guaranty No Water Leaking in Long Period of Time
6) Recommend a Bright one, Dark Type Hides all the defect.
7) Do you Job Slowly and Neatly. Workmanship is an Art. Respect your own Workmanship.

End User

1) Keep the Formal Receipt, It can be use against the contractor or the manufacturer in a court of Consumer Law
2) Google for more info
3) You Buying Asset, which add value to you home.

Just to share the glass awning of my house, frame with louver installed, left glass to be installed this week...can't wait to see the final.outcome.

I was thinking glass but if tiles from upper roof slid off and hit the glass 

I saw glass stained after a while and it is hard to maintain it 

Just using 10mm laminated glass only, becos thats fit my budget for that. They quote 58/square ft without louver, additional 11/sqft for louver. I add 50% louver coverage, total price 23.5k after 5% discount when i give full payment at once. Anyway, i stay in JB which i believe the price is higher than KL, but this is by far the cheapest i found here.

steel frame and poly awning...only last 6 years... recently heavy rain and strong wind took this awning down...
