NEXFIL Expands Architectural Film Business into Hotels and Restaurant Chains

Responding to demand for improved indoor environments in large facilities, company strengthens collaborations built on its Icheon production base and overseas supply experience

SEOUL, South Korea, Nov. 11, 2026 /PRNewswire/ -- Window film manufacturer NEXFIL is broadening its business into architectural and commercial facilities, including hotels and restaurants. Building on collaborations with a major domestic hotel, an environmental and hygiene specialist, and a franchise restaurant chain, the company is expanding the number of sites where its architectural films are installed and responding to demand for better indoor environments in large facilities.

According to NEXFIL, its architectural films are being applied at a major domestic hotel, an environmental and hygiene specialist company, and a large franchise burger restaurant, among other sites. Building on the architectural product line it has operated alongside its automotive films, the company is pursuing collaborations tailored to the operating objectives of each facility.

The company cites prolonged heat waves and growing demand for indoor environment management as the background to these collaborations. NEXFIL believes that reducing indoor heat load from sunlight and maintaining a comfortable environment have become key challenges for large facilities. In response, it is extending the use of films that manage heat entering through windows to hotels, restaurants, and similar venues.

NEXFIL said it is collaborating with the hotel and the environmental and hygiene specialist to manage pest entry and create more comfortable indoor environments. At the large franchise burger restaurant, its film is also being used to improve the comfort of the space. Drawing on this field experience, the company plans to further expand collaborations in the hotel, food service, and environmental sectors.

The company's architectural film business is supported by its own research and production system. Founded in 2001, NEXFIL develops and manufactures window film at its corporate research institute and production facilities in Icheon, Gyeonggi Province. The company handles the entire process in-house, from base film processing and coating to sputtering and finished product manufacturing, and operates both architectural and automotive product lines.

Its core production technology is a multilayer sputtering process. By forming multiple metal layers on the film to reflect solar heat, the process serves as the main technological foundation of NEXFIL's architectural and automotive heat-rejection film businesses. The company also cites as a competitive strength its domestic production of wide-width sputtered film, which requires advanced process technology.

NEXFIL expanded its production capacity in 2025 by adding a wide-width sputtering line. Backed by its own manufacturing base, the company pursues domestic installations and overseas supply in parallel. According to NEXFIL, approximately 93% of its total output is exported to more than 60 countries worldwide.

Product performance is disclosed through metrics such as infrared rejection rate (IRR) and total solar energy rejection (TSER). NEXFIL presents clear visibility alongside heat rejection as a key product characteristic, and also cites its patents and high-efficiency energy equipment certification as part of its technological foundation.

As it grows, the company plans to continue pairing product supply with training for installation partners. Drawing on its experience producing in Korea and supplying multiple overseas markets, NEXFIL aims to widen the range of installation sites and expand market touchpoints through collaboration with installation partners. It also plans to pursue its premium multilayer sputtered film business in overseas markets, including the United States.

NEXFIL is also focused on promoting broader uses of window film through collaborations with large facilities. Building on the business experience gained from automotive products and its architectural film production base, the company intends to address demand for managing indoor environments in buildings and commercial spaces. Converting real-world applications at hotels and restaurants into further collaborations is the task ahead.

Alongside business expansion, the company places weight on improving the accessibility of sputtered film. NEXFIL's position is that films using multilayer sputtering technology should be available within the existing price range of each market. Rather than limiting such products to the high-end segment, the company says it aims to raise customer satisfaction and market value together by making high-performance films more widely available.

"We plan to expand collaborations with large facilities in the hotel, food service, and environmental sectors," NEXFIL said. "Based on our experience producing in Korea and exporting to more than 60 countries, as well as our training of installation partners, we will set a new standard for premium multilayer sputtered film in overseas markets as well."
