Saving Energy and Securing the Future
In 2004, Turkish uPVC window manufacturer Winsa became part of the Ege Profil Group. Since then, Winsa’s growth has accelerated significantly. We spoke with Deputy General Manager Batuhan Boyacı about the company’s future plans.
“We have built a unique network of showrooms and distribution partners in Turkey,” says Boyacı, naming one of the key pillars of Winsa’s success. This network allows Winsa to offer close customer proximity and comprehensive service. The second pillar, he explains, is energy-efficient plastic building components developed with advanced technology.
“Winsa developed Turkey’s first Passive House-certified profile system.”
This achievement significantly boosted brand awareness. Producing in an environmentally conscious way and continuously developing products that reduce building energy consumption is a core mission for Winsa. New components are tested and optimized on in-house test benches according to international technical standards.
Tightly sealed
For the past year, Winsa’s product range has included the Comfort Slide Plus sliding system, which features the high-sealing Roto Patio Inowa parallel sliding hardware. “Since its launch, demand has developed exceptionally well,” reports Boyacı. In 2025, sales of this type of sliding system rose significantly. And for good reason, says the industry expert. Users immediately notice the system’s exceptional ease of operation..
“Our partners recognize the sophisticated technology of Patio Inowa and praise the sealing performance of Comfort Slide Plus.”
Numerous systems were installed in 2025 in both residential buildings and hotels. “Our dealers report that Comfort Slide Plus gives them a clear competitive advantage in projects.”
Quick and easy to assemble
Ease of installation was also a key reason Winsa chose Patio Inowa. “Our factory staff say that assembling it is as simple and straightforward as following instructions for a toy.
The hardware can be installed in a significantly less time than other sliding systems. On- site installation is also easy, and adjustment and maintenance are particularly simple. “These are, of course, crucial aspects for the long-term success of a product,” Boyacı adds.
Partner for the Future
Winsa’s positive feedback extends beyond the Patio Inowa hardware. After a year of collaboration, the executive’s conclusion is clear:
“We rely on flexibility and an efficient production process with maximum delivery reliability. Roto guarantees that 100 %.”
Deliveries are always punctual and exactly as agreed. “That’s extremely important for us as a modern industrial company,” he emphasizes. “In the future, it will become increasingly important to work in perfect sync with partners we can rely on.”
Roto provided excellent support during the development and production launch of Comfort Slide Plus, Boyacı concludes. “Even before production began, we experienced a constructive and highly professional collaboration with Roto that continues to this day. The rapid and significant success of Comfort Slide Plus is also a testament to the quality of Roto’s service.”
Technology Leader
Winsa currently employs over 400 people. Over the past four years, the company has produced an average of 500,000 windows and 140,000 sliding elements annually. Boyacı emphasizes that Winsa is now a technological leader in all product segments — “and not just in the Turkish market.” The company aims to continuously increase its export share. That’s why Roto’s global market presence and extensive experience are so valuable to Winsa. The same applies to Roto’s expertise in engaging and supporting architects.
Starting in 2026, Winsa plans to further expand its project-based sales approach, especially its support for planners and investors in large-scale projects, Boyacı announces. “We can offer architects optimal components tailored to specific rooms and buildings that always improve energy efficiency and provide additional value for users,” explains the Deputy General Manager. He is confident that Winsa will continue to grow soon. This is made easier not least by the choice of strong partners. “ Deceuninck and Roto are internationally successful companies that have our back.”
A perfect match? Boyacı smiles. “Based on our experience so far, absolutely.”
