Tostem is advancing its business in sustainable aluminum doors and windows, reinforcing its commitment to product development through innovation that harmonizes technology for coexistence between people and the environment. The company has launched the campaign “Connecting Spaces of Living” along with TOSTEM’s new interior series, designed to enhance quality of life and modern living experiences by seamlessly connecting indoor and outdoor spaces. This will be showcased for the first time at the Architect Expo 2025, the largest architecture and construction technology exhibition in ASEAN, taking place from April 29 to May 4, 2025, at Challenger Hall 1-3, Impact Muang Thong Thani.

Mr. Wicha Worasayan, Leader of the Housing Technology Business Group at LH T Asia Sales and Marketing Co., Ltd., the manufacturer of aluminum doors and windows under the TOSTEM brand, part of LIXIL Corporation, stated that TOSTEM remains committed to developing comprehensive living solutions. This is reflected in the launch of the campaign ‘Connecting Spaces of Living’, which focuses on harmoniously and seamlessly linking both indoor and outdoor spaces while prioritizing sustainability.

The Connecting Spaces of Living campaign is not just about communicating new products; it also reflects TOSTEM's vision of creating seamlessly connected living spaces that suit modern lifestyles emphasizing flexibility, well-being, and harmony with the environment. The core of this new campaign is to present housing solutions designed with the resident at the center, adaptable to needs, and creating a perfect connection between different areas within the home. TOSTEM will unveil new innovations through TOSTEM's new interior series at Architect Expo 2025, a significant platform for showcasing design and innovation potential in housing.

TOSTEM's new interior series – Innovations for perfect interior spaces. The highlight of this booth is the launch of TOSTEM's new interior series, designed with a focus on harmonious and seamless aesthetics, concealing screws and hardware within the frame for a clean and luxurious look. It includes three main products to be showcased at Architect Expo 2025:
1. New Hanging Door – A sleek, modern sliding door system with high flexibility, perfectly adaptable to usable spaces, featuring an overhead rail and technology that prevents door wobbling (world premiere at Architect Expo 2025).
2. New Swing Door – A minimalist swing door design with concealed hinges for smooth operation and a clean appearance.
3. New Fixed Divider – A partition that enhances design flexibility while maintaining openness in the space.

The inspiration behind the TOSTEM booth design, along with special promotions at Architect Expo 2025, aims to impress visitors with a booth that concretely reflects the concept of "Connecting Spaces of Living." Designed by Khun Phakorn Mahapan, an architect from M SPACE, the booth design draws inspiration from sliding doors used to connect spaces in Traditional Japanese Rooms, allowing multiple rooms to connect seamlessly. The booth structure is designed as a series of sections that gradually twist from a gabled roof in the center of the building, transforming into walls at both ends, creating a continuously changing spatial form every meter, based on a stable Tatami Room structure that facilitates endless space connectivity, allowing customers to experience the display area of TOSTEM products seamlessly.

Additionally, TOSTEM is set to offer marketing activities for customers at Architect Expo 2025, such as completing the dream home with products from all Tostem series, with credit card payments free of fees for products and installation services. Promotions include Early Bird offers for the first 10 homeowners who pay for Tostem products via credit card with a minimum amount of 50,000 baht, receiving a Central gift voucher worth 4,000 baht, and the Friend to Friend promotion where homeowners who have installed Tostem products and recommend friends to purchase Tostem products via credit card will both receive a Central gift voucher worth 4,000 baht each. These promotions run from April 29 to October 31, 2025, through participating dealers.

Mr. Wicha further stated that the launch of the campaign 'Connecting Spaces of Living' and the TOSTEM's new interior series marks a significant step for TOSTEM in expanding its business to become a leader in comprehensive housing solutions. We are confident of a positive response from customers, partners in design and construction, designers, architects, and interior designers looking for solutions that blend beauty and efficiency. The overall business goal for TOSTEM in 2025 is to achieve a 20% growth in total sales, while continuing to implement plans to expand the market to customers, including property developers seeking to develop sustainable projects and choose environmentally friendly materials following the launch of PremiAL 100 last year, as well as self-build customers who prioritize design and quality of life. There are also plans to expand the market to retail homeowners, increasing market share in the Upper Mass - Luxury Segment. TOSTEM is also collaborating with business partners to expand TOSTEM Studio, managed by dealers, to cover more areas in provinces, focusing on major cities and tourist destinations to reach customers in residential, resort, and home-building companies in those areas.

Currently, TOSTEM Studio has opened 15 locations in Pathum Thani, Phitsanulok, Udon Thani, Khon Kaen, Nakhon Ratchasima, Bangkok, Samut Prakan, Songkhla, Kanchanaburi, Chiang Rai, Chonburi, Ubon Ratchathani, Chiang Mai (2 locations), and Nakhon Pathom, in line with plans to expand showrooms nationwide for consumer access to choose, experience, and see actual products.
