Tinted cermin kereta ni ada tiga kategori/sifat.
No satu VLT (Visible Light Transmission), kedua UV (Ultra-violet) dan ketiga IR (Infra-red).
Secara detailnya penerangan seperti dibawah,
– VLT (Visible Light Transmission): Consider this carefully if you do not want to get into trouble with JPJ. As above stated, please do not exceed the amount. Please be also advised that our stock glass / window do have a certain negative percentage of VLT simply meaning do not choose tint VLT up to 70% exactly for your windscreen as your stock windscreen may have, e.g. -2% VLT, simply brings to 68% VLT only
– UV (Ultra-violet) Rejection: Having a high UV % is recommended. Most of the high-end good tint brand usually have up to 99% UV rejection. It is important as UV radiation can lead to faster ageing of the skin and risk of having skin cancer caused by ultra-violet rays.
– IR (Infra-red) Rejection: IR simply mean heat. The higher IR rejection a tint have, the better it will do in head shielding. If you guys are looking for tints that can really keep your car cool, look for tints that have high IR rather than VLT. However, high IR tints usually cost a fortune.
Secara ringkasnya apa yang kita perlu tahu, untuk UV Rejection kebanyakan tinted memang 99% memantulkan radiasi ini.Dan jika kita nak kereta kita sejuk pilih tinted yang IR Rejection tinggi %nya. Semakin tinggi, semakin mahal. Dan VLT tak berapa penting sebab bukan nya bila lebih gelap cermin kereta kita,lebih sejuk. Yang mempengaruhi sejuk kereta kita selepas tinted adalah kadar peratus balikkan IR. Kesimpulannya, jangan habiskan duit beli tinted yang gelap, tapi beli tinted yang tinggi peratus balikan IR. Yang biasa2 tinted pantulan IR sehingga +-50% dan yang terbaik 99% keatas.
