Dekko Window Systems has broadened its aluminium product offering with the introduction of the Aluna Bi-fold and Aluna Sliding Patio Door, both manufactured using Alunet Systems’ high-performance aluminium profiles. This expansion enhances Dekko’s position in the glass and fenestration sector, complementing its established Reynaers and Decalu ranges and giving installers greater choice for premium projects.
The Aluna Bi-fold is designed for modern living, featuring ultra-slim 107mm frame-to-sash sightlines, smooth operation, and exceptional thermal efficiency. It offers up to 14 sashes in inward or outward configurations, providing flexible design possibilities.

The Aluna Sliding Patio Door delivers a sleek architectural finish with a minimal 25mm interlock and sash sizes reaching 2.5 metres wide. Available in sliding or lift-and-slide options, it combines contemporary style with PAS24 security compliance, weather resistance, and effortless operation.
The Alunet range also includes Aluna+ windows, entrance doors, and internal glass screens, making Dekko a comprehensive supplier of aluminium glazing solutions.
