A118 No Drill 1% Openness Twill Solar Shades with Large Tube (38mm)

A 1% openness factor means the fabric is tightly woven, allowing only 1% of light to pass through. This provides superior glare reduction and excellent UV protection while still maintaining a filtered view of the outdoors, making it ideal for rooms with direct, intense sun exposure.

Our No Drill shades feature a high-tension, pressure-fit mounting system. This mechanism creates consistent lateral force against your window frame, ensuring a secure, non-slip installation that stays perfectly in place without the need for drills, screws, or wall damage.

The 38mm large tube offers superior structural rigidity compared to standard 28mm tubes. This is critical for 1% twill fabrics, as it prevents bowing or sagging on wider windows, ensuring the textured fabric hangs straight and rolls smoothly every time.

The twill weave provides a distinct, elegant diagonal texture that adds depth to your interior design. Beyond aesthetics, the twill construction enhances the fabric's dimensional stability and durability, making it more resistant to fraying than standard plain weaves.

No. Our mounting brackets are equipped with premium, non-slip, protective pads. These pads distribute pressure evenly across the frame to ensure a firm grip without leaving scratches, dents, or marks, making them perfect for rental properties or delicate custom frames.

1% solar shades offer excellent privacy during the day. However, at night, when interior lights are on, silhouettes may be visible from the outside. If you require absolute night-time privacy, we recommend pairing these shades with curtains or opting for a blackout-lined product.

Yes. The larger tube diameter provides greater mechanical leverage, resulting in a smoother, quieter, and more responsive rolling action. It feels significantly lighter to operate, even when the shade covers large or wide window spans.

For an inside mount, measure the precise width of your window opening at the top, middle, and bottom, and use the narrowest measurement. Ensure your frame has at least 7cm or 2.76 inches of depth to accommodate the tension-mount brackets securely. View Our Step-by-Step Measurement Guide.
