A Seamless Connection to the Outdoors

Our lift and slide aluminium doors are among our most popular solutions, designed to bring a sense of scale and elegance to any home. With expansive glass panels and slim sightlines, they create striking panoramic views while maintaining excellent security and energy efficiency.

Maximising natural daylight, these doors help reduce the need for artificial lighting — lowering energy costs and creating brighter, more inviting living spaces. Ideal for wide openings in new builds, extensions, and renovation projects, they combine innovative engineering with contemporary design.

The AP400 is a premium aluminium lift-and-slide system, specifically designed for large openings such as patios, terraces, and garden façades. It delivers the perfect balance of strength, thermal efficiency, and ease of use.

Engineered for Performance and Elegance

How the Lift & Slide Mechanism Works

The lift-and-slide principle is what sets the AP400 apart from a standard sliding door. The mechanism is elegantly simple — and immediately noticeable in everyday use.

1

Turn the Handle

Rotating the handle engages the lifting rollers, raising the door panel slightly off its seals and reducing friction to near zero.

2

Glide Smoothly

With the panel lifted, even the heaviest sashes glide along the track with minimal effort — smooth and quiet throughout.

3

Lower & Seal

Lowering the handle returns the door to its sealed position, compressing firmly against the weather seals for an airtight, weathertight closure.

Built to Meet and Exceed Irish Building Standards

Manufactured from high-quality aluminium alloy with a polyamide thermal break, the AP400 delivers exceptional durability, low maintenance and a lifespan measured in decades.
