Star Heat Shield® IRUV CUT COAT for Construction and Architecture
Your Ultimate Heat & UV Protection Solution

Q: What is a thermal insulated glass coating for window glass?
A: The installation of a roller shade on the interior side of window glass effectively blocks direct sunlight during the summer months while also minimizing heat loss from the interior during winter. This can lead to a reduction in air conditioning expenses by 25-30% by decreasing the overall cooling demand. The thermal barrier glass coating is designed to filter out both infrared and ultraviolet rays.

Q: What are the characteristics?
A: During the summer months, when sunlight strikes the window glass, approximately 60% of the solar heat is absorbed by the glass that has been treated with an IRUV cut coating. Of this absorbed heat, nearly 40% is re-radiated back outside. This coating effectively reduces direct solar heat by 5°C to 15°C, resulting in a temperature decrease of 2 to 3°C within the room.

Q: What is the cutting rate of infrared rays?
A: In terms of infrared rays, the wavelength associated with the direct heat from the intense summer sun is classified as near infrared. STARSHIELD boasts a near-infrared cut rate of 90%, whereas most other glass coatings achieve a near-infrared cut of 50% or lower. It is important to clarify that the 90% or greater cut rate for far-infrared rays, which contribute to heating during winter, is also referred to as infrared rays. This can lead to potential misunderstandings regarding its effectiveness in providing heat-shielding during the summer months. STARSHIELD effectively prevents the warmth from winter heat from escaping through the window.

Q: Is there a UV cut feature? How can I verify if the UV is cut?
A: The STARSHIELD -IRUV cut coat offers a UV cut rate exceeding 99%. Consequently, the following benefits can be anticipated: it protects flooring from UV degradation, prevents the fading of display items such as clothing and bags, and helps to avert spots and freckles caused by UV damage to the skin.

Q: Is it successful in reducing condensation?
A: While condensation cannot be entirely eliminated, it can be minimized by 50% or more. Although condensation may still form and appear white, the formation of water droplets is significantly decreased. Additionally, there are fewer cold spots on the window.

Q: Which time of day experiences the highest level of heat insulation during the summer?
A: Direct solar heat penetrates the room most significantly in the morning from the east, at noon from the west, and in the evening from the south. However, the insulated surfaces are protected from temperatures ranging from 5℃ to 15℃ compared to uninsulated surfaces. There is minimal variation on surfaces that do not receive direct sunlight. Between 10 AM and 4 PM, when air conditioning systems are under the most strain, the temperature increases lead to a wider heat shield effect. Extensive temperature measurement data is available, confirming the differences in temperature.

Q: Is there a tint present? Is it not dark?
A: The color tint is nearly transparent. The visible light transmittance (transparency) is approximately 10-15% lower than prior to the application of the coating. While the visible light transmittance of a typical automobile windshield is around 70%, this coating material is about 75% more transparent than that of a car windshield, giving it an almost transparent appearance.\

Q: What is the lifespan of the STARSHIELD application, and what occurs once this period has elapsed?
A: The application boasts a durability of 15 years or longer following a single application, specifically for indoor coatings. After exceeding the 15-year mark, the UV protection begins to gradually diminish, leading to a slow deterioration where the acrylic resin may turn white. At this stage, it can be removed with a suitable remover, allowing for re-application.

Q: What distinguishes it from film?
A: There are four categories of film. The first is a crime prevention film, characterized by a thickness ranging from 200 to 350 microns. The second type is an anti-scattering film that includes UV protection. The third is a colored sunshine adjustment film, also featuring UV protection. The fourth type is a transparent thermal barrier film combined with anti-scattering properties. Among these, the fourth type, the transparent thermal barrier film, stands out as a competitive option. Notably, this film boasts a UV cut rate of 99%, comparable to the STARSHIELD coating. In addition, the STARSHIELD IR coating offers several advantages:
• It is more cost-effective to apply.
• Its durability exceeds twice that of standard films, with weather resistance lasting over 10 years.
• Typical film durability ranges from 5 to 7 years.
• It is straightforward to install and remove.
• Unlike film, it does not have seams.
• There is no reflection at night.
• It is less prone to thermal cracking compared to traditional film.

Q: There is an odor associated with the application of the coating, but how long does it take to dissipate?
A: Once the coating is installed, it typically dries within 30 minutes during summer and 1 hour in winter. The odor generally dissipates within 2 to 3 hours if the window is fully opened. However, if the window cannot be opened or closed, the smell may linger until the following day. To alleviate concerns about the odor post-application, it is advisable to use a negative ion or ozone generator for deodorization. As the coating is solvent-based, it emits a scent similar to nail polish remover, which gradually fades over time. Nevertheless, for several hours after application, ventilation may be limited, causing the odor to accumulate in smaller, confined spaces.

Q: Is it safe for children and pets to accidentally lick the surface? Does the formulation contain any harmful substances?
A: Consuming the paint in its liquid form poses a risk; however, if it is licked after it has dried, there are no concerns. To date, there have been no reported incidents of such issues. For further assurance, please refer to the product's safety data. The ingredients do not contain any of the 14 items classified as TVOC, and there is no leaching of harmful substances such as formaldehyde, acetaldehyde, toluene, xylene, or benzene after application.

Q: Is it free from scratches?
A: The pencil hardness test indicates a hardness level of 4H. Therefore, if it is at a level that does not harm the glass, it will remain undamaged.

Q: What should be considered for care following application? What precautions should be taken when cleaning window glass?
A: The complete curing process requires two weeks during the summer and four weeks in the winter, so it is essential to wait at least one month before cleaning. Additionally, since the surface is only susceptible to caustic soda (alkaline substances), it is advisable to clean the window using only water or a neutral detergent. Please be aware that any issues arising from the use of other cleaning agents will not be covered by the warranty.

Q: What type of case is assured for the application?
A: An application is guaranteed at no cost if yellowing, cloudiness, or peeling arises within a 10-year period, provided that it is not due to the customer's negligence. However, applications made on the film are excluded from this guarantee.

Q: How long does it take to dry?
A: The drying time varies: finger contact drying takes between 30 to 60 minutes, and it is safe to touch after a duration of 3 hours.

Q: What is the rationale behind using an inner window? Can an exterior window be utilized instead?
A: While it is feasible to install a window on the exterior, certain conditions, such as inclement weather, may hinder this process. Additionally, the cost of erecting scaffolding for high windows can be prohibitive. Furthermore, even if an exterior window is installed, its longevity cannot be assured due to issues like acid rain. Therefore, if considerations such as cost, durability, or warranty are paramount, we suggest opting for an interior window installation.
