In this case, because many of us already know the VLT worth of the window and the final VLT worth we need to achieve we all simply have to have in order to rearrange the formula to calculate typically the suitable tint in order to install as follows:

V3 (final VLT worth ) � V1 (VLT of glass) = V2(VLT value of tint)

. thirty (30%) �. seventy five (75%) =. 40 (40%)

In accordance with this particular formula, installing the window tint along with a VLT value of 40% will outcome in the final VLT value of 30% while preferred.
