Aluminium Sliding Doors

Superior insulation and energy efficiency from advanced aluminium sliding technology, for a home that is comfortable, economical and environmentally responsible.

Wide openings, one finger

Aluminium allows the largest sashes and the narrowest sections. In our sliding systems that means floor-to-ceiling glass, an almost invisible frame and smooth movement even on sashes weighing hundreds of kilos.

We work with Reynaers and Cortizo, fit factory-calibrated lift-and-slide hardware, and install with our own team under a 10-year warranty.

Sashes up to 3.5 m
Panoramic openings in a single sash, up to 500 kg.
Uw desde 0,9 W/m²K
Thermal break and triple glazing for year-round comfort.
Flush threshold
A continuous line between inside and terrace, with no visible step.
Coastal resistance
Anti-corrosion Qualicoat coating, made for coastal exposure.

Which sliding system to choose

Not every opening needs the same mechanism. The choice depends on the width, the weight of the glass and how much of the opening has to be genuinely clear.

Lift-and-slide (HST)
The sash lifts before it slides. This is the answer for the heaviest sashes and the best weathertightness. Hi-Finity and MasterPatio.
Minimal-profile sliding
A concealed interlock and profiles reduced to a few centimetres of sightline. SlimPatio 68 and COR Vision.
Multi-track sliding
Up to three tracks and four moving sashes to clear most of the opening. 4900 Corredera.
Bi-folding
The sashes stack against one another and open almost the entire span. Bifold Plus.

SKLO technical note: above 3 m of sash width, lift-and-slide almost always beats plain sliding — it seals better against wind and driving rain, and takes no more effort to operate.

Finishes

Aluminium can be powder coated in a wide range of colours and finishes, so the frames suit both the architecture and the interior. RAL colours, textured finishes and wood-effect options are available.

RAL colour chart for aluminium powder coatingLacado RALA wide selection of RAL colours, available in smooth, matt or textured finish.
TIGER textured powder coating samplesLacado texturado / TIGERTextured, highly resistant powder coating for projects that want a matt, long-lasting surface.
Wood-effect finish samples for aluminiumWood effectA decorative finish that reproduces the natural look of timber while keeping the strength and low maintenance of aluminium.

Glass and hardware

The profile is only part of the window. Glass and hardware decide thermal comfort, noise and security

Glass

Saint-Gobain and Guardian glass with low-e coatings, solar control and acoustic or safety lamination. The glazing package sets the final Uw of the opening.

Hardware

Reynaers and Cortizo lift-and-slide hardware, factory calibrated, with multi-point locking and rollers sized to the weight of the sash.
