Deceuninck North America debuted its new 205 Patio Door system at GlassBuild America 2026, the company reported. The PVC sliding patio door platform targets fabricators looking to reduce component inventories and simplify production while supporting larger door sizes and higher structural and thermal performance.

The company introduced the system at GlassBuild America, held Sept. 23-25 in Las Vegas. Deceuninck displayed the 205 Patio Door at booth 1531.

Deceuninck developed the platform around several production issues facing window and door manufacturers, including inventory requirements, assembly complexity and demand for larger units. According to the company, the system reduces the number of components by nearly 50% compared with its previous approach.

Fabricators can use the same core system components to produce either a welded frame or a mechanically assembled knock-down, or KD, frame. The latter allows manufacturers to ship frame components unassembled for final assembly closer to the installation site.

The 205 uses a tower-style sliding door design rather than a conventional pocket-style configuration. When closed, the sash straddles and overlaps the frame, creating greater engagement between the two components.

Deceuninck said that design allows an 8-by-8-foot configuration to reach a DP50 rating. Design Pressure, or DP, ratings indicate a fenestration product’s tested resistance to structural wind loads and other performance requirements.

“The new patio door system came directly from conversations with our customers,” said Greg Koch, interim president and vice president of sales and marketing at Deceuninck North America. “Fabricators were looking for a tower-style patio door that could provide strong performance without adding complexity to their operations.”

The company also reports that the system can achieve a U-factor as low as 0.22 without using a triple-pane insulating glass unit (IGU). U-factor measures heat transfer through a fenestration product, with lower values indicating better insulating performance.

The combination of larger sizes, fewer components and alternative frame-assembly methods reflects a broader focus among North American fenestration system suppliers on reducing fabrication complexity while maintaining performance. The approach can be particularly relevant for manufacturers trying to consolidate SKUs, simplify inventory management and serve residential and light-commercial projects from a common platform.

A similar focus on streamlined fabrication and flexible system architecture appeared elsewhere at GlassBuild America this year. Related: REHAU Brings New NUVERA Hung and Slider Window Platform to U.S. Market.
