FAQs
The 38mm tube provides enhanced structural rigidity compared to standard 28mm tubes. This prevents the shade from bowing or sagging, ensuring a perfectly straight roll and preventing the fabric from fraying at the edges, even on wider windows.
Semi-sheer shades are designed to filter and soften sunlight, reducing glare while allowing natural light to enter the room. They offer excellent daytime privacy. Blackout shades, by contrast, are designed to block 100% of light for complete room darkening.
Semi-sheer shades provide excellent privacy during the day. However, at night, when interior lights are on, silhouettes may be visible from the outside. If you require complete privacy at night, we recommend layering them with curtains or opting for a blackout shade.
Yes. The 38mm heavy-duty tube is specifically engineered to support wide window spans. Its increased torque and stability make it the ideal choice for large living room windows or sliding glass doors where smaller tubes would likely bend or fail.
Yes. Our premium semi-sheer fabric is engineered to filter out a significant percentage of harmful UV rays. This helps protect your furniture, flooring, and interior decor from fading while allowing you to enjoy a bright, comfortable, and sun-filled environment.
Yes. The larger tube diameter provides greater mechanical leverage, making the shade feel lighter and more responsive. This results in a much smoother, quieter, and more consistent rolling action than what is typically found in budget-grade roller systems.
Inside mount offers a clean, flush-to-the-frame look, perfect for a custom-built appearance. Outside mount is recommended if your window casing is too shallow for the 38mm hardware or if you want to maximize light coverage and make the window appear larger.
Routine maintenance is simple. Use a feather duster or a soft, dry microfiber cloth to remove surface dust. For spot cleaning, use a slightly damp cloth with mild soap. Avoid harsh chemicals to preserve the fabric's specialized light-filtering weave.
