The relationship between light and heat-Solar radiation spectrum

According to AIMCAL, The Association of International Metallizers, Coaters and Laminators, and IWFA, International Window Film Association, when the temperature of an object itself reaches 50℃, heat radiation is generated. Nonetheless, transparent films block less than 82 percent solar radiation. Some companies mislead their consumers into believing that simply blocking infrared radiation can efficiently prevent solar radiation entirely. This is not correct because infrared radiation is not the only component of solar radiation, which is composed of 53 percent infrared radiation, 3 percent ultraviolent and 44 percent visible light. Moreover, materials’ heat absorption usually affects the quality of thermal insulation.
Heat sources
Direct sunlight + heat dispersion via air + thermal conduction through objects (Including a second radiation from glass)

Specification and features of Window Film-IBF
High transparency: High visibility, without glare and interference with ETC and GPS reception.
High heat rejection: Excellent heat rejection due to containing non-metal ATO thermal insulating layer, which efficiently reduces heat from windshields, creates comfort driving.
◆High clarity: Using PET film substrate, which has high transparency, makes the line of sight of a driver clear to ensure the safety of driving
Ultraviolent rejection: Blocking more than 99% ultraviolent to prevent skin from sunburn and to prevent car interior parts from cracks.
Attractive appearance and abrasion resistance: Containing abrasion resistance coating layer reinforces the surface of IRBLOC and keeps its appearance new.

Application of Window Films

Window Film

-- Containing PSA, which can adhere to glass, such as windows to block ultraviolent rays and solar radiation,
prevent glass fragments, and adjust sunshine etc.
-- Being mainly applied to automobiles, buildings, and decoration for indoor windows
