Advanced Solar Control Film for Radiant Heat Rejection in Belem, Brazil

The adoption of solar control film in Belem has evolved in response to the city’s unique climatic demands and growing energy awareness. Historically, glass buildings in the region suffered from excessive solar heat gain, leading to high energy consumption for cooling. Over the past decade, the market has shifted from basic tinted films to advanced spectrally selective and reflective technologies. KASKI has been part of this progression, supplying films that address the specific challenge of infrared heat rejection while minimizing visible light reduction. The development has been driven by the need for better thermal comfort in commercial spaces, such as those in the Campina district, and in modern residential condominiums along the Guama River. Today, the focus is on durable, high-performance films that can withstand the local humidity and temperature variations.

KASKI’s commitment to quality ensures that installers and end-users in Belem receive products with consistent performance, backed by manufacturer qualifications and warranty support.

Silver Reflective Film for Maximum Heat Rejection

Silver reflective solar control films are designed for applications where maximum solar energy rejection is the primary objective. In Belem, where the sun’s intensity is high year-round, these films offer a shading coefficient as low as 0.21, effectively blocking 78% of summer solar heat. The one-way mirror effect provides daytime privacy, making it ideal for ground-floor retail stores and office buildings. KASKI’s Reflective Silver 15 film, for example, delivers 79% total solar energy rejection with a visible light transmission of 15%, balancing heat control with visibility. This film type is particularly effective for large glass facades that face the sun directly, reducing glare by 83% and protecting occupants from harsh light. For more details on dual reflective options, see our dual reflective film page.

Dual Reflective Film for Enhanced Interior Visibility

Dual reflective films provide a distinct advantage in Belem’s commercial environments by maintaining a low interior reflectance, which improves outward visibility. The DR25 film, for instance, has an interior visible light reflection of only 12%, compared to 29% exterior reflection. This allows building occupants to enjoy clear views of the cityscape without the mirror-like effect on the inside. These films still offer robust heat rejection, with a solar heat gain coefficient of 0.35 and 57% summer solar heat reduction. This makes them suitable for office buildings and hotels where aesthetics and occupant comfort are priorities. KASKI’s dual reflective films also reduce glare by 75%, enhancing visual comfort for computer work and meetings.

Sputtered Film for Color Neutrality and Performance

Sputtered solar control films are manufactured using a process that creates a uniform transmission across the visible spectrum, resulting in excellent color balance. For architects and designers in Belem, this means the film does not distort the natural appearance of glass or the colors of the interior. These films meet NFRC 302 standards for energy performance, providing reliable data for building energy modeling. KASKI’s sputtered films offer a balance of heat rejection and light transmission, suitable for buildings where maintaining a neutral aesthetic is critical. They are ideal for historical buildings or modern structures where the original glass color must be preserved. To explore more options, visit KASKI’s main site.

The technical performance of KASKI solar control films is defined by key parameters that directly address the climate of Belem. The Solar Heat Gain Coefficient (SHGC) is a critical metric; for example, the Reflective Silver 10 film has an SHGC of 0.18, meaning it allows only 18% of solar heat to enter. The Total Solar Energy Rejected (TSER) is another vital figure, with values reaching 82% for high-performance films. Ultraviolet protection is consistently above 99% across all product lines, preventing fading of furniture and flooring. The U-value, which measures heat transfer, is also important for maintaining indoor temperatures. Film thickness, typically 60 microns for reflective films and 43 microns for dual reflective films, ensures durability and ease of installation. These parameters are verified through ASTM E903 testing, providing confidence for specifiers. KASKI’s films are also designed with scratch-resistant coatings to withstand cleaning and handling in Belem’s humid conditions.
