Naturo 80 HST ALU
Naturo 80 HST ALU is a timber-aluminium lift-and-slide system: natural timber inside and aluminium protection outside, with reduced maintenance.
The system allows large glazed areas, is comfortable to operate and shields the external face from the weather. The exterior look can be tailored through the Gemini Classic, Gemini Quadrat, Mira, Mira Contour and Mira Contour FB variants.

Choice of materials
Timber laminated in three or four layers is more stable than solid wood, does not move with humidity and allows arches and curved shapes.
Solid timberSolid pineNo visible joints, long sections free of natural defects, made for clear varnishes that show the grain
Finger-jointed laminateFinger-jointed pineDefect-free sections joined end to end by finger joints: maximum stability, ideal for opaque finishesSKLO technical note: above a 3 m opening, or with strong sun exposure, we recommend 80 mm laminate — the dimensional stability is worth the extra cost
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.
