"Cost of the solar films are base on InfraRed Rejection(IRR)."
The higher the IRR(heat rejection)the higher the cost.
There are many unknown IR films in the market which you cant see the spec on the film.
Therefore,in order to be fair to Yourself and Geniune vendor,
Insist for an IR meter measurement on the spot.
This is just the basic assurance that the tinting vendor should provide.
Do not buy "verbally spec"..
make sure you get the actual IRR that you are paying for.
