EnglishAluminium Windows
Slim sections for wide openings, with thermal breaks specified to the system and the calculation
Four Reynaers and Cortizo systems from 68 to 99 mm deep — from an ultra-slim profile for refurbishment to an industrial concealed-sash system
Slim profiles, wide openings
Aluminium carries large sashes: more glass, less frame, with weathertightness confirmed by calculation. Uw from 0.8 W/m²K in a compatible configuration
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.
Lacado RALA wide selection of RAL colours, available in smooth, matt or textured finish.
Lacado texturado / TIGERTextured, highly resistant powder coating for projects that want a matt, long-lasting surface.
Wood effectA decorative finish that reproduces the natural look of timber while keeping the strength and low maintenance of aluminium.Profile construction
Two routes to the same goal: less visible frame. The choice depends on the facade design and the weight of the sashes
Classic casementVisible sashStraight lines and classic proportions, with 68 to 77 mm profiles, three seals and the best cost-to-performance ratio
Folha ocultaFolha ocultaThe sash hides behind the outer frame: from outside you see only glass and a thin line of aluminium, with up to 85% glazed areaSKLO technical note: on south-facing facades, pair the thermal break with solar-control glass — it cuts overheating without darkening the room
Glass and hardware
The profile is only part of the window. Glass and hardware decide thermal comfort, noise and security
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 is Roto or Siegenia, with multi-point locking, trickle ventilation and hinges adjustable on all three axes.
Glazing bars
They give a window character and echo classical architecture. We choose the type according to the look you want and the energy performance required
StructuralAluminium bars in the sash colour, physically dividing the opening into panes
Inside the glassAluminium bars inside the sealed unit. Widths of 8, 18, 26 and 45 mm
BondedBonded to the glass with a warm-edge or silver central spacer, in the sash colour
Swisspacer Ultimate spacer
As an alternative to the standard aluminium spacer we fit a high-performance warm-edge spacer. It reduces condensation around the edge of the glass and lowers heat transfer across the whole window
Available in a wide range of RAL colours to match the frame

Aluminium does not rot and powder coating removes the need for regular repainting. Properly coated and properly installed, it holds its appearance for many years with minimal external maintenance, and at end of life it is fully recyclable
Other ranges
Aluminium is not the only right answer: for high insulation on a controlled budget, or for the warmth of timber, look at these ranges too
