Sustainable heat management: Why window films are the future defence against rising heat

As the Indian subcontinent and its cities become warmer every year, keeping our indoor spaces-homes or workspaces-cool and naturally bright has become increasingly challenging, and in many cases, almost a dream. Large glass windows and modern architectural designs add to the premium look but also attract and absorb unnecessary heat inside the building. During summer, prolonged exposure to sunlight keeps the room well-lit but also raises indoor temperatures significantly, making indoor spaces uncomfortable. This results in consumers becoming heavily dependent on cooling solutions such as air conditioning systems or coolers, which in turn adds to electricity and energy consumption.

Consumers are constantly on the lookout for solutions to this ongoing challenge, and Cosmo Sunshield’s Ultra Cool 7090 – a next-generation window film – addresses this need. Manufactured by Cosmo First – a trusted brand in specialty films and polymer technology -these films are the product of four decades of polymer-based solution manufacturing expertise. Designed accordingly, the Ultra Cool 7090 is highly capable of controlling the entry of visible light while balancing transparency, protection, and temperature control. Such innovations also reflect the company’s commitment to introducing smart, sustainable solutions tailored for modern living and environmental needs.

Unlike conventional films available in the market that often make customers choose between visibility and performance, the Ultra Cool 7090 seamlessly blends both, redefining industry standards and perceptions of what window films can offer. With Nano Ceramic Technology, the films achieve an exceptional 70% Visible Light Transmission (VLT), while simulta-neously rejecting 90% of infrared radiation, which causes indoor heat buildup. This helps consumers enjoy a naturally lit environment and safe space, ensuring cooler temperatures even during peak summer seasons.

This film also provides over 99% UV protection—a much-needed feature in window films. This helps preserve interior design, especially colours and textures, as well as furniture, upholstery, and artwork—which usually degrade or get damaged with prolonged sun exposure. The Cosmo Sunshield Ultra Cool 7090 variant thus adds an extra layer of safety and comfort for indoor spaces without compromising aesthetics. The result—a protective shield that complements and helps modern architecture retain its glory and appeal from heat and glare.

Additionally, one of the biggest advantages of Cosmo Sunshield’s Ultra Cool range of window films is their energy-saving ability; by blocking unwanted heat and reducing the extra load on ACs and cooling solutions, they reduce electricity consumption by up to 20%. Furthermore, they ensure optimal thermal insulation, delivering consistent indoor temperatures at any time of the day. For towers and buildings with large glass facades, this film—and the entire window film portfolio from Cosmo Sunshield—offers dual benefits for customers: comfort and cost efficiency.

The window film portfolio from Cosmo Sunshield is a smart, climate-adaptive solution that works equally well in Mumbai’s humid coastal weather as in Delhi’s dry summer heat. In a country like India, exposed to abundant sunlight and extreme weather, Ultra Cool films are among the best-suited and most practical solutions. Without excessive reliance on energy-intensive cooling solutions, window films are helping architects and homeowners create comfortable spaces that are brighter and cooler-all while reducing environmental impact.

Today, Cosmo Sunshield window films are redefining how polymer technology blends design, performance, and energy efficiency to solve crucial challenges. As energy awareness grows among consumers, window film stands as a powerful solution for a cooler, greener, and more sustainable way of living.
