NEDO · Toray Industries Develops Innovative Thermal Insulation Film – High Transparency and High Level Thermal Insulation
Toray Industries has developed a thermal barrier film that combines transparency comparable to glass and the world’s highest level of thermal insulation.
The heat-Selectively cut infrared rays that cause temperature rise in sunlight
39% compared to normal clear glass,
11% compared with commercially available high performance / transparent thermal barrier film
We were able to confirm the cooling load reduction effect of
By sticking to windows etc. of buildings, we aim to realize energy saving of air conditioning power and aim to reduce greenhouse gas emissions.
2. The result of this time
(1) selective reflection of light by innovative layer arrangement design
Thickness of each layer of film and design of material
Introduced innovative layer sequence design
Suppresses reflection of visible light
Improve infrared cut performance only
The world’s highest level of thermal barrier achieved
(2) High precision laminating technology of film
Device design based on Toray’s original flow simulation
Combining ultra-high precision film forming process
Even with a 1 nm layer thickness, it is possible to control film uniformly
We also offer large area heat shield film which can also correspond to window glass of office building
(3) Confirmation of effect by developed heat shielding film
Heat shielding film developed this time
Environmental Harmony Experiment Building at Chubu Center of National Institute of Advanced Industrial Science and Technology
Heat shock test using a new measurement method to extract components caused by solar radiation from the cooling load
as a result,
39% of normal clear glass,
11% compared with commercially available high performance / transparent thermal barrier film
We confirmed the effect of cooling load reduction.
