Ventilation. Light. Total security.
One window that does the job of three: continuous airflow, natural light, and side-to-side security bars built into every louver — no exposed grilles, no compromise. Engineered under NSR-10 and manufactured in our Barranquilla plant for Puerto Rico, the Caribbean and the U.S.
A louver window that is also the security system.
Every louver carries a steel security rod that passes from frame to frame. Close it and you have a wall of aluminum; open it and the house breathes. Children stay safe without a single exposed bar on the façade.

Side-to-side security bars
A steel rod runs through each louver and anchors into both jambs. Even with the louvers open, nothing gets through — the protection is inside the window, not bolted on the outside.
Aluminum louvers
Extruded aluminum blades, powder-coated with an electrostatic finish. Choose white, black or a custom color. They never rust, never warp, and clean with a cloth.
Glass louvers 4" × ¼"
For rooms that want daylight: 4-inch glass blades, ¼" thick, held in the same security frame. Clear, tinted or frosted.
Double anti-leak felt seal
Two felt seals per louver stop water infiltration in tropical rain and hurricane conditions. Optional on every unit.
Crank operator
A single operator opens and closes every louver at once — smooth, silent, and out of reach from outside.
Heavy-duty extruded frame
Profile SFIT003 — 50.80 × 41.65 mm — designed under Colombia's NSR-10 seismic building code. Built to be installed once.
Insect screen & continuous airflow
Optional anti-insect mesh on the interior side. The window ventilates in every position — even fully closed to the eye it keeps the air moving.
