Modern Sliding Door Technology

Palmako Slide Plus systems are designed to bring natural light, garden views, and contemporary styling together in one premium glazing solution. Featuring large glass panels within robust aluminium frames, these systems create bright, open interiors while maintaining excellent weather protection and everyday practicality.

Double-Glazed Comfort

The Slide Plus system incorporates high-performance 24mm double glazing, consisting of two toughened safety glass panes separated by a 16mm cavity. This construction helps improve thermal performance while contributing to a quieter interior environment, with sound reduction of up to 35dB.

Palmako Slide Doors And Windows

Premium Aluminium Construction

Manufactured from powder-coated aluminium, the Slide Plus framework is designed for long-lasting durability and minimal maintenance. Finished in Anthracite Grey (RAL 7016), the sleek profiles complement both modern and traditional garden buildings while offering excellent resistance to weather exposure.

Smooth and Effortless Operation

High-quality roller mechanisms, reinforced bearings and precision-engineered sliding rails ensure smooth opening and closing. Each door panel operates on its own dedicated track, allowing panels to slide freely and providing flexible access options depending on the building design.

The Slide Plus system has been developed to provide outstanding protection against wind and rain. Multiple sealing features, including interlocking door profiles, wind-lock technology, brush seals and dual weather gaskets, help create a secure barrier against the elements. Integrated drainage channels within the lower track assist water management and help prevent moisture ingress.

Enhanced Security Features

For added peace of mind, Slide Plus doors are fitted with toughened safety glass and secure locking mechanisms. Anti-lift protection helps prevent door panels from being removed from their tracks, while internal and external locking points provide secure everyday operation.
