A118 1% Openness Twill Solar Shades with Large Tube (38mm)

A 1% openness factor means the fabric weave is extremely tight, allowing only 1% of light to pass through. This provides maximum glare reduction and excellent UV protection while still allowing for a soft, filtered view of the outdoors during the day.

The 38mm large tube provides superior structural rigidity compared to standard 28mm tubes. This prevents the roller from bowing or sagging on wider windows, ensuring your shade rolls up and down perfectly straight and maintains the integrity of the twill fabric over time.

These shades offer high daytime privacy because the tight 1% weave makes it difficult for outsiders to see in while the room is brightly lit. However, at night, when interior lights are on, silhouettes may be visible from the outside.

Maintenance is simple. Use a feather duster or a soft, dry microfiber cloth to remove dust regularly. For minor spots, dab with a damp cloth and mild soap. Avoid harsh chemicals or abrasive scrubs to protect the specialized twill weave.
