The darkest series is V-Kool 40 which about 42% VLT
I not sure you can pass SG custom or not but I thought Singapore do not have
rules on the tint ?

Have you visit showroom to view or test the film?

Yes, the best among V-Kool film. actually 42% not really dark.
On the road should be ok but not PUSPAKOM

You did at my shop ! How is the performance ya?

No matter how thick you put in either 1 or 2 layer, your glass window still break.
The safety film purpose is shattered resistant.

www.saharax.com
Its HOME BRAND, the film is from USA
I couldn't find any international website about this product


You can but the product warranty will be void. You can install clear 4Mil or 8Mil safety film and
that will cost you around RM100 - 300 per pcs

Depends on your budget =)

Try to search at groupon, you can find the price between rm200 - rm400

The price you get is quite reasonable =) what is the product name?

This is good to share around about the infra red rejection

VKool elite TSer is 55%, it still better than sech 60%.
Simple reason,

VKool Elite VLT 70% , TSER 55%
Sech 60 VLT60% ++, TSER 54%

If the film darker the TSER should be better

Another smart consumer =D SC is very important.
The lower is better -)

TSER + SC = 100%

When you select windows film, you have select the VLT% then only look into SC and TSER.
Normally, windows film company recognize by IWFA http://www.iwfa.com/ always show SC vs TSER in their specifications. The windows film made from Japan, Korea or China did not have SC reading.

Measuring TSER & SC is very difficult as we need all the basic info about the glass and its surrounding such as temperature, thickness of glass and more. This normally apply to commercial or residential building.

Sorry this should be ok
http://advancedfilmfl.net/files/72745-6383..._Rev0709_lo.pdf

Since the Raytech film from USA and well recognize by IWFA. Why the product specification do not have Shading Coefficient or Solar Heat Gain Coefficient reading? It is very important to have this data to determine the film TSER performance.

Thx, I just miss out =)

To select the best heat rejection film, you have to determine the VLT that you want because it will affect the rest of the performance. For instant example,

We have
1. Spectrally selective window film means the film always have high VLT, Low VLR and High Rejection
For example, the spec will be 70% VLT, 8% VLR, 99% UV,0.5 SC and 55% TSER. This film is more suitable for automotive to meet up our JPJ rules.

2. Non spectrally selective window film means the film can have better performance by lower their VLT and increase
their VLR. For example, the spec will be 20% VLT, 50% VLR, 99% UV, 0.2 SC and 80% TSER. This will against the JPJ rules, thus it more suitable for architectural application.

Lets talk about IRR, this bit technical. We measure IRR in nanometer. In nanometer we measure

1. UV (0-380 nanometer)
2. VLT (380-780 nanometer)
3. IRR (780-up to 2400 nanometer)

For the 1st and 2nd reading, the measurement of nanometer is short, therefore the percentage is always 100% accurate, that's why most the windows film claim have 99% of UV rejection.

When come to IRR measurement, some of the windows film claim they have 95% IRR rejection but when tested with equipment such as 500 watt heat lamp, it burn faster than the one who claim have 90% IRR. This because the windows film that come IRR 95% take their IRR reading at 780-1000 nanometer or even lower. That where the films performs the best meanwhile the windows film that have 90% IRR have their reading at 780-2000 nanometer or even more. Read here for more

Some of the HOME BRAND do not have the accurate specification. They normally buy the windows film in bulk and rebrand or remodified the windows film with great specification to boost the sales. That's why important go for International Brand because we always send our product to lab testing and get verification.

Yes, branding is very important. Do you expect Proton have same quality with Honda? We put more effort, research, consumers feedback, consumers needs and etc in the product. As windows film seller, product knowledge is necessary skill for us to explain to the consumers. If you have encounter salesperson that could not answer any your basic question, I guess you can just walk away from that shop.

I'm just sharing this rating by NFRC, http://search.nfrc.org/search/apd_film/fil...ch_default.aspx
My company product

Southwall Technology - Huper Optik and V-Kool
Saint Gobain - Solar Gard

This one of the best website to prove the ratings in US. http://www.nfrc.org/WindowRatings/

Of course you can -) just ignore what SA tell you and go search yourself

Both also HOME BRAND, nothing no mention except the thickness is good.

Are you serious that you cant claim the warranty due to rusty? Give me call at 016 9269 780 I help you to claim if still within the warranty. Make sure you have warranty card with you.

Its either their own brand or Ecotint. But normally those free tint the quality is low. You can remove and put new layer as double layer is not recommended because it will void product warranty.
