Cortinas enrollables opacas premium A130 con tubo grande (38 mm)

The 38mm large tube provides significantly higher structural rigidity than standard 28mm tubes. This prevents the roller from bowing or sagging on wider windows, ensuring smooth, consistent operation and preventing the fabric edges from fraying over time.

Yes, these shades use a high-density, multi-layer blackout fabric specifically engineered to block 100% of light penetration. They are ideal for creating a pitch-black environment in bedrooms, nurseries, or home theaters.

The larger diameter tube reduces the number of rotations needed to raise or lower the shade. This places less mechanical stress on the internal spring or clutch system, extending the overall lifespan of the shade compared to smaller-diameter alternatives.

Absolutely. The 38mm system is designed for wide spans where standard rollers often fail. Its enhanced weight capacity and torque ensure the shade remains stable and level across its entire width without bending.

Yes, the thick, premium blackout fabric acts as a thermal barrier. It effectively blocks solar heat during the summer and helps retain indoor warmth during the winter, contributing to better energy efficiency and lower utility costs.

Choose an inside mount for a sleek, flush look, provided your window frame has at least 7cm or 2.76 inches of depth. Choose an outside mount to maximize light blockage, hide an unattractive frame, or if your window casing is too shallow for the 38mm mounting hardware.

Maintenance is simple: use a soft, dry microfiber cloth or a feather duster for regular cleaning. For stubborn spots, lightly wipe with a damp cloth using mild soap. Avoid harsh chemicals or abrasive scrubs to protect the light-blocking coating.

While the tube itself is more robust, the premium clutch system is designed to provide greater mechanical leverage. This makes the shade feel effortless to operate, allowing for smooth and controlled movement even on larger window sizes.
