Frequently Asked Questions

The Cosmo Sunshield Rainbow Series is an advanced carbon-pigmented sun control window film with a non-reflective finish. It is designed to provide solar protection, UV protection, glare reduction, daytime privacy and improved energy efficiency while maintaining a refined appearance.

The Rainbow Series material describes the product as an advanced carbon-pigmented film, but it does not specifically use the term "nano-pigment" or explain a nano-pigment technology. The film's listed solar-control performance includes infrared heat rejection, total solar energy rejection, UV rejection and glare reduction.

The Rainbow Series is a non-reflective window film. Its material specifically describes the film as having a non-reflective finish, making it suitable for applications where a mirrored appearance is not desired.

The product material identifies the Rainbow Series as carbon-pigmented film and the samples shown are black/dark in appearance. The material does not explain the reason behind the "Rainbow" name, so a specific explanation for the naming should not be assumed.

The Rainbow Series is a 2-ply, 1.5 mil window film. The product specifications shown in the material identify the construction as 2 Ply, 1.5 Mil.

The Rainbow Series is identified as a carbon-pigmented film, rather than a dyed film. The provided material does not give a technical comparison between dyed and pigmented film construction, so the difference should not be stated beyond this product specification.

The Rainbow Series provides different levels of infrared heat rejection depending on the VLT variant. The specifications shown range from 20% to 75% infrared heat rejection. Rainbow 05 provides the highest listed infrared heat rejection at 75%, followed by Rainbow 15 at 60%, Rainbow 20 at 50% and Rainbow 70 at 20%.

The Total Solar Energy Rejected (TSER) varies by Rainbow Series VLT: Rainbow 05: 61%, Rainbow 15: 53%, Rainbow 20: 50% & Rainbow 70: 22%. TSER indicates the percentage of total solar energy rejected by the film/glazing system under the stated test conditions.

The SHGC (G-value) varies by Rainbow Series film: Rainbow 05: 0.39, Rainbow 15: 0.47, Rainbow 20: 0.50 & Rainbow 70: 0.77.

The shading coefficient varies according to the Rainbow Series VLT: Rainbow 05: 0.44, Rainbow 15: 0.52, Rainbow 20: 0.56 & Rainbow 70: 0.87.

The Rainbow Series is specified as an advanced carbon-pigmented film with a non-reflective finish. Its material demonstrates infrared heat rejection and total solar energy rejection without describing a metallic or reflective construction. However, the provided material does not explain the detailed mechanism by which the carbon-pigmented construction achieves this performance.

The Rainbow Series is presented as helping provide reduced energy consumption, which is one of its listed benefits. Its solar-control properties can reduce the amount of solar energy entering through the glass, but the provided material does not give a specific percentage reduction in air-conditioning load.

Yes. The Rainbow Series rejects more than 99% of ultraviolet radiation in the listed variants. Rainbow 05, Rainbow 15, Rainbow 20 and Rainbow 70 all show >99% ultraviolet rejection in the provided specifications.

Glare reduction varies by VLT: Rainbow 05: 94%, Rainbow 15: 84%, Rainbow 20: 78% & Rainbow 70: 22%. The lower-VLT Rainbow variants therefore show higher listed glare reduction in the supplied specifications.

Yes. Daytime privacy is one of the listed benefits of the Rainbow Series. The level of visual privacy will depend on the selected VLT and lighting conditions. The darker 5% VLT option provides a significantly darker appearance than the higher-VLT options.

The provided Rainbow Series material does not specify a night-time privacy rating. Night-time privacy can depend on the lighting conditions inside and outside the building, so the film should not be described as providing complete privacy at night based on this material alone.

The supplied material confirms more than 99% UV rejection, which provides UV protection for the space. However, it does not specifically state that the Rainbow Series prevents furniture, flooring or interiors from fading. Therefore, it is better to describe the product as providing UV protection rather than guaranteeing protection against fading.

Rainbow 05 has the highest listed infrared heat rejection and TSER among the Rainbow Series variants shown in the material. It provides 75% infrared heat rejection and 61% total solar energy rejection, along with 94% glare reduction.

Rainbow 70 allows the most visible light through, with a listed 70% VLT. It also has 22% total solar energy rejection and 20% infrared heat rejection. Therefore, it is the highest-VLT option shown in the supplied Rainbow Series material.

No. The Rainbow Series has a non-reflective finish, so it is not designed to create the mirrored appearance associated with reflective window films.

The Rainbow Series may be suitable for applications where a non-reflective window film is preferred, because it has a non-reflective finish rather than a mirrored appearance. However, approval ultimately depends on the specific rules of the housing society, builder, property manager or local authority.

The Rainbow Series can alter the appearance of glass because it is a tinted, carbon-pigmented film, but its non-reflective finish is designed to provide a more seamless appearance rather than a mirrored façade. The product material specifically highlights a "seamless blend of performance and refined aesthetics."
