Dekko Window Systems expands product portfolio with Alunet bi-fold and sliding door
August 13, 2025
Leading trade fabricator Dekko Window Systems has strengthened its aluminium offering with the launch of the Aluna Bi-fold and Aluna Sliding Patio Door, manufactured using Alunet Systems’ high-performance aluminium profiles.
The addition of these sleek, high-spec systems means Dekko now offers customers three distinct aluminium bi-fold and patio door solutions: the Reynaers range, Decalu range, and now Aluna from Alunet.
Steve Collett, Sales Director at Dekko, Window Systems, comments: “Aluminium continues to be a strong growth area. Even with cautious consumer spending, homeowners are still looking for aspirational, high-end products that enhance their living space – and that points directly to aluminium.
“Expanding our aluminium portfolio allows us to give installers the choice and flexibility they need to win more business.”
The Aluna Bi-fold boasts ultra-slim sightlines of just 107mm frame-to-sash, smooth opening and closing, and exceptional thermal performance. It’s designed for flexible living, offering up to 14 sashes with inward or outward opening configurations.
Meanwhile, the Aluna Sliding Patio Door delivers a sleek architectural finish, with an interlock of just 25mm and sash sizes up to 2.5m wide. Available in sliding or lift-and-slide versions, it offers excellent weather performance, PAS24 compliance, and effortless operation.
“Bi-fold doors remain incredibly popular, but there’s been a clear shift towards sliding patio doors, particularly those with ultra-slim sightlines,” added Steve. “With the introduction of Aluna, we now offer three premium aluminium systems that cover all project types – giving our customers a real competitive advantage.”
Dekko’s Alunet range also includes the Aluna+ window (Slim Flush/Standard/Tilt Turn Window) the Aluna entrance door and Aluna internal screens.
