Luxa 100 Zip Screen

The Luxa 100 is a motorised exterior ZIP screen system designed for facades, windows, and glass curtain walls. Unlike interior blinds that only reduce glare after solar heat has already entered the building, the Luxa 100 can reduce solar heat gain depending on project conditions before it reaches the glass — making it one of the most effective passive cooling strategies available.

The patented ZIP rail mechanism guides the screen fabric within aluminium side channels using a continuous zip fastener on both edges. This eliminates wind uplift, fabric fluttering, and light gaps that plague conventional roller blinds. Wind resistance: reviewed for project wind exposure (Beaufort 12).

The Somfy IO tubular motor operates silently (<40 dB) and integrates with wind sensors, sun sensors, and rain sensors for fully automatic operation. Maximum single-screen dimensions: 5,500 mm width × 4,500 mm height (24.75 m²).

Screen fabrics are available in three categories: Sunscreen mesh (1–10% openness factor for daylight and outward visibility), translucent (diffused light without view), and blackout (0% openness for complete darkness). All fabrics carry Oeko-Tex Standard 100 certification and are fire-rated to EN 13501-1 Class B-s1,d0.

Energy performance: external ZIP shading can reduce cooling demand depending on orientation, glazing and fabric openness. The g-value (solar heat gain coefficient) drops from 0.6 to under 0.1 with a ZIP screen deployed. This is recognised in green-building assessments when project data is documented.
