A113 Kein Bohren 5% Offenheit Sonnenschirme mit kleinem Rohr (28mm)

A 5% openness factor provides the optimal balance between glare reduction and outward visibility. It allows enough natural light to maintain a bright, airy room atmosphere while filtering out approximately 95% of harsh UV rays and eliminating glare on screens and furniture.

Our No Drill system utilizes a high-tension, pressure-mounted mechanism. By using adjustable, high-friction rubberized end caps, it creates a secure and stable grip against the window frame. This allows for a professional-grade installation in minutes without the need for drills, screws, or permanent damage to your property.

The 28mm small tube is specifically engineered for a sleek, low-profile fit. It is ideal for window frames with limited mounting depth where standard 38mm systems would appear bulky. It keeps the aesthetic minimalist and unobtrusive while ensuring reliable, smooth operation.

No. The system is designed with protective, non-slip silicone pads that distribute tension evenly across the frame. These pads prevent scratching, denting, or marring the finish, making them the ultimate rental-friendly window treatment that leaves no trace when removed.

For an inside mount, measure the precise interior width of your window frame at the top, middle, and bottom, then use the narrowest measurement. Ensure the frame has a minimum depth of 6cm or 2.37 inches to provide adequate surface area for the tension system to seat securely. View Our Step-by-Step Measurement Guide.

Yes. Our 28mm system features a high-precision, reinforced clutch mechanism. It is expertly calibrated to handle the tension and weight of the solar fabric, ensuring smooth, silent, and reliable operation that resists jamming over time.

Absolutely. The 5% solar fabric acts as a high-performance thermal barrier. It reflects intense solar energy, significantly lowering indoor temperatures during hot seasons and improving the overall energy efficiency of your living space.

During the day, the 5% openness creates a 'privacy screen' effect; it is difficult for outsiders to see in while you enjoy a clear view of the outdoors. Note that at night, when interior lights are on, silhouettes may be visible, so they are best suited for living areas or paired with curtains for bedroom privacy.
