Aesthetics

Designed to enhance any architectural style, the Aluna slider features expansive glass panels and minimal sightlines thanks to an ultra-slim interlock of just 25mm and bottom rails of 42mm and 34mm wide for uninterrupted views and natural light. Marine-grade aluminium frames offer a sleek, contemporary appearance available in any RAL colour.

Performance

Built with Alunet’s product innovation at its core, Aluna sliders accommodate sash sizes up to 2.5m x 2.7m, with a maximum sash weight of 250kg per door leaf. Advanced engineering enables exceptional quality, weatherproofing, and energy efficiency, delivering thermal insulation as low as 1.4 U W/m²K for a more comfortable living environment, as well as soft closing technology for smooth operation.

Security

With PAS24:2022 compliance and a robust multipoint locking system, Aluna patio doors are designed to deliver complete peace of mind. Premium stainless-steel hardware and reinforced profiles provide UK homeowners with long-lasting safety and security features making it a top choice.

    The windows look fantastic

    "Recently used Dekko Windows to supply the windows and aluminium bi-fold doors for our renovation project. We paid a short visit to their showroom where Rob and Neil were really helpful, showing us around and providing options for us. We were really happy with the whole process and the windows look fantastic. Would definitely recommend this company."
