GLASTEN is an aluminum window and door brand that develops systems specifically for architectural applications, based on a design concept that integrates aesthetics, technology, and the performance of modern window and door systems.
Mr. Phisit Jirapakul, Managing Director of Glasten (Thailand) Co., Ltd., believes that the main reason GLASTEN has consistently participated in Architect Expo is because its primary users are architects and designers—those who play a key role in selecting and specifying window and door systems in line with an building’s design intent.
At the same time, many homeowners are still not familiar with European-style or specialized window and door systems. Architects therefore often act as advisors, helping translate and communicate these systems so that project owners can make informed choices that truly align with design requirements.
As window and door systems become better understood by users
Through continuous participation in Architect Expo, GLASTEN has clearly observed the market’s evolution, especially in recent years.
Mr. Phisit recalls that when the company first introduced Thermal Break systems in Thailand, many users were unfamiliar with the concept and often asked what it was and how it functioned in real applications.
However, over the past 4–5 years, user understanding has significantly improved, particularly among architects and designers who increasingly recognize the role of window and door systems as a critical component of building performance.
Today, many visitors arrive at the booth already familiar with the systems they are looking for, reflecting a Thai market that is continuously evolving and increasingly open to international material technologies.
Windows and doors as a key building component
The main system developed by GLASTEN is the Thermal Break System, which separates the inner and outer aluminum layers of a window or door frame. The core principle is to reduce heat transfer through the frame, preventing outdoor temperature from directly affecting indoor conditions.
In Thailand’s hot climate—where interiors typically rely heavily on air conditioning—this system plays an important role in reducing HVAC load and improving overall energy efficiency.
This concept also aligns with current architectural trends that emphasize green building principles and energy-efficient design.
International technology and local development
GLASTEN’s products are partially imported, especially components and systems developed in Europe. The company sources hardware and systems from countries such as Germany, China, and other European nations, before assembling and adapting them in Thailand to suit local architectural conditions.
One key collaboration is with Technoform from Germany, a global developer of Thermal Break technology. This partnership enables GLASTEN to develop window and door systems that meet both performance standards and real-world architectural needs.
Designing for large-scale architecture
Designing for large-scale architecture
One of GLASTEN’s key strengths is its ability to support large-scale architectural applications, especially luxury residential projects requiring wide openings. System design must consider structure, load-bearing capacity, and safety performance.
Mr. Phisit emphasizes that large windows and doors are not simply about increasing size, but require careful engineering consideration—from load distribution and hardware calculations to safety mechanisms.
This approach requires a balance between engineering precision and architectural design thinking.
GLASTEN highlights at Architect’69
For Architect’26, GLASTEN will present several new window and door systems.
One highlight is the Slimline sliding system for large openings, capable of spans up to approximately 9 meters wide and 3 meters high. It is available in both manual and motorized versions that can be integrated with home automation systems.
Another highlight is the Slide & Compress system, a sliding door system with full perimeter sealing, offering thermal and acoustic insulation performance comparable to hinged doors.
In addition, new Slimline window systems feature ultra-thin frames, designed to maximize viewable glass area and enhance spatial continuity between interior and exterior environments.
Technology and services that build user confidence
Beyond product development, GLASTEN places strong emphasis on after-sales service, which is a key decision factor for luxury residential clients.
The company provides a 3-year product warranty along with a dedicated service team that supports customers throughout the product’s lifecycle.
Mr. Phisit believes that properly designed and installed systems from the beginning can significantly reduce long-term issues—something customers value more than frequent repair visits.
Experience GLASTEN systems at Architect’26
At GLASTEN’s booth, visitors will explore window and door systems developed for contemporary architectural design—from Thermal Break systems that enhance energy efficiency to solutions for large-scale openings that are increasingly popular in modern residential and commercial projects.
In addition to product displays, visitors can also explore GLASTEN’s design philosophy, which integrates building performance, user safety, and new possibilities in architectural openings.
Architects, designers, and project owners are invited to experience GLASTEN’s latest window and door technologies at Booth D107 during Architect’26, the 38th ASEAN’s largest architecture and building technology exhibition, held from 28 April – 3 May 2026, 10:00–20:00 at Challenger Hall 1–3, IMPACT Muang Thong Thani.
