FAQs
A 38mm large tube provides superior structural rigidity, which prevents the shade from bowing or sagging in the middle. This ensures your shade rolls up and down perfectly straight, eliminates fabric fraying at the edges, and allows for smooth operation on wider window spans.
Yes. These shades utilize a multi-layered, high-density blackout fabric designed to block 100% of light transmission. They are the ideal choice for bedrooms, nurseries, or home theaters where total darkness is required for better sleep or screen visibility.
Yes. The premium, high-density material acts as a thermal barrier. It helps block intense solar heat in the summer and retains indoor warmth during the winter, which can lead to improved energy efficiency and reduced cooling or heating costs for your home.
The larger 38mm tube diameter increases the mechanical leverage of the roller system. This makes the shade feel lighter and more responsive to operate, providing a much smoother, quieter, and more consistent roll compared to smaller, budget-grade roller mechanisms.
Absolutely. The 38mm heavy-duty tube is specifically engineered to support wider spans that standard 28mm tubes cannot handle. It offers the stability and strength needed for large living room windows or expansive glass doors.
We recommend routine dusting with a soft cloth or feather duster. For deeper cleaning, you may use a damp sponge with mild, non-abrasive soap. Always allow the fabric to dry completely while fully extended before retracting the shade to prevent moisture buildup.
Inside mount provides a sleek, custom-built appearance that fits flush with the window frame. Outside mount is ideal if you have shallow window depths, desire maximum light coverage to eliminate 'light gaps' on the sides, or want to make the window appear larger.
Yes. Every order comes with a complete, heavy-duty installation kit, including the 38mm-compatible brackets, screws, and hardware covers. These brackets are designed for both wall and ceiling mounting to ensure a secure, professional-grade fit.
