Are WINALUM and FENSTELA the same? Here’s an explanation
Many customers, contractors, architects and homeowners still ask whether WINALUM and FENSTELA are the same company. This is understandable, as FENSTELA is indeed the continuation of the WINALUM brand, which has been well-known for many years.
FENSTELA is the evolution of WINALUM
For over 40 years, our company has built a reputation as a specialist in aluminium doors and windows in Indonesia. Previously, our products were known as WINALUM. In line with the company’s growth, product innovation and our vision to deliver more modern, internationally standardised aluminium systems, we have rebranded as FENSTELA. This change is a step towards strengthening our corporate identity without compromising our commitment to quality, innovation and service.
Is the current WINALUM still affiliated with FENSTELA?
No.
The WINALUM brand currently available on the market is not part of FENSTELA and has no connection with our company. In other words, products bearing the WINALUM name are not currently manufactured, marketed or guaranteed by FENSTELA.
Why Is This Important?
Many customers still assume that all products bearing the WINALUM name come from the same company as before. In reality, however, the quality of materials, production systems, quality control standards, product specifications, and even after-sales service may differ. Therefore, we recommend that customers ensure the products they choose are actually from FENSTELA if they want the quality and standards we have built over decades.
