Hello Sifus.

I am looking to install a car porch, and have been checking around for quotes. Based on what I gathered, it seems like ACP (Aluminium Composite) is the cheaper option these days even when compared to polycarbonate, at least around Klang Valley.

There were a few things shared by those salesmen which I'm hoping to verify with experienced friends here.

1) ACP 4mm vs PC 3mm - definitely ACP is a better bet that it will last longer vs PC.
2) ACP can cut off heat better than PC (mainly due to cutting off sunlight).
3) Combining both ACP And polycarbonate is NOT recommended - high potential of leaks as they are different thickness and materials
4) ACP is actually now cheaper than PC (e.g. RM 2-3 cheaper per sq feet).

Other than the above however, one of the salesmen revealed that there is also something called the Zinc PU. Quoted at the same price as ACP, he told me this is like a much enhanced version of the old-school zinc awnings. Basically they sandwich a PU Foam in-between two zinc pieces, and that practically can outlast any other materials other than maybe glass. However it is not preferred simply because it's just very 'old style'. Plus, the edge needs to be covered up to make things look 'nicer'.

Is anyone aware about this material? If you have heard about it or are (or decided against) using it, could you also please share your experience with it? E.g. noisy when raining, really a viable alternative etc. It would help give me better understanding about the trade-offs for each.

Thank you.

PU looks better from top

ZPU, corrodes over time, hence the need to repaint is there, initially it looks nice and glossy.

PU has 4mm as well.

I went with ACP+Glass, since I need sunlight.

Are you talking about PU metaldeck?

Seems like you already make the decision on ACP...

Just to confirmed your decision is okay or not...

For me... ACP is okay... Not much issues

How much price u get for ACP? Cheapest i found is RM16/sqft

Yes. I double-checked. Some call it Metal PU, others call it Zinc PU.

Wow, RM16? The quotes that I got are between RM24-26/sqft. Includes all the thrusts and beams + workmanship. Beams and gutter is extra.

RM16 without gutter.
Structure and pillar inclusive but if u want to change pillar to stainless steel need to add few hundred just for the pillar, if u worry rust.

My opinion: I think this is the best roofing material. Lasts long, insulated from sound and heat, low maintenance, reasonably cheap, and I think it looks okay. If you actually use it as a roof, then it is low slope capable too.

Against it are the look might not appeal to everyone and that if you require translucence, then of course it is not suitable.

The link in my original reply has some videos, and the installations look decent (to me) with the hidden gutters and hidden edges. Also no need for underside cosmetics as it looks okay from underneath too.

Nice! Which supplier did you use ? Could you pass me to the contact so that I can also ask them for a quote.

need permit from majlis to install ?

i would like to suggest PU panel if you have the budget.
as my porch need curve roof, i have to go with ACP

Hi, did TS go through with the SkyRoofing RM16/sqft? If so how's the workmanship/roof now?

is pu metal ugly?

Try look for uPVC Corrugated Roofing.
similar to metal deck, but light weight, durable, corrosion free, good heat insulation.



Similar price with Metal Deck with PU Foam

uPVC (1.45mm thickness) : ~RM9 per ft (3/2025)
metal pu foam (0.35mm thickness) : ~ RM8.9 per ft (3/2025)

it look just like a normal metal roofing, but with PU insulation directly below.

Is this inclusive of installation?

Nop.. material cost only.
