Many Solar Film companies use misleading metrics to promote the film's heat rejection capabilities like TSER (Total Solar Energy Rejected), which gives disproportionate weight to visible light rather than actual heat rejection.
The TSER formula typically follows this structure:

TSER = (0.44 × VLT) + (0.53 × IRR) + (0.03 × UVR)

As shown, 44% of the TSER value comes from visible light transmission (VLT), while infrared rejection (IRR)—which is more directly responsible for heat—is weighted at just 53%, and UV rejection only 3%. This can result in a film appearing to perform well on paper even if it’s ineffective at rejecting real thermal energy.

Scientifically, the infrared spectrum responsible for most solar heat gain extends from around 720nm to 2500nm, with the most impactful heat radiation occurring beyond 1400nm. Unfortunately, many manufacturers only report IR rejection over a narrow band (typically 900–1000nm), which doesn’t reflect real-world performance but is rather used to show favorable misleading results. At our company, we take a more transparent and scientifically accurate approach by measuring IR rejection across the full solar IR spectrum—up to nearly 3000 nanometers. This gives our clients a far clearer picture of true heat-blocking capability, particularly in demanding environments like the GCC.

Our top tier films have undergone a stringent Volatile Organic Compound (VOC) Test:
These films achieved a VOC emission level of 0.0095 mg/cm², which is five times lower than the allowable rate of 0.05 mg/cm². This exceptionally low rate not only reflects superior material quality but also indicates enhanced thermal stability. As a result, the film is significantly more durable under heat exposure and better able to maintain its insulation performance over time, making it a reliable and long-lasting choice for both automotive and architectural applications.
