Honeycomb Construction and Insulation Performance
The 400 Series uses double-cell honeycomb construction—two layers of cellular fabric that create pockets of trapped air between your window and your room. This design delivers exceptional thermal insulation, keeping warm air in during winter and blocking heat gain in summer.
Our polyester cellular fabric is engineered with UV-resistant polymers that maintain color integrity even in direct sun exposure. The 400 shades achieve an R-value comparable to foam insulation, making them one of the most energy-efficient window covering options available. Homeowners installing our cordless cellular shades across multiple rooms report noticeable reductions in monthly energy bills.
Custom Sizing and Fit
Measuring for Your 400 Series Shades
We manufacture every 400 shade to your exact specifications. Measure your window width at the top, middle, and bottom—use the narrowest measurement to ensure a proper fit. For length, measure from the top of the window frame to the sill.
Our custom sizing accommodates windows from 12 inches to 96 inches wide and up to 96 inches in length. For best results, we recommend inside-mount installation where the shade sits within the window frame for a streamlined look. Outside-mount options are available for windows with insufficient depth or for maximum light blockage.
Cordless Operation and Safety Features
Traditional corded blinds pose strangulation risks for young children and pets—that’s why we designed the 400 Series with a cordless lift system as standard. Raise and lower your shades with a gentle push or pull on the bottom rail, and our friction-hold mechanism keeps them securely in place at any position.
The cordless design also delivers a cleaner aesthetic without dangling cords interrupting your window view. Parents and pet owners appreciate the peace of mind, while design-conscious homeowners love the uncluttered look.

Questions About the 400 Series Cordless Cellular Shades
The 400 Series features double-cell (two-layer) honeycomb construction for superior insulation and energy efficiency, while our 300 Series uses single-cell construction. The 400 provides a higher R-value and better temperature regulation, making it ideal for extreme climates or rooms with high energy costs.
Both series offer cordless operation and custom sizing, but the 400 delivers approximately 40% better insulating performance. If maximum energy savings matter most, we recommend the 400 Series investment.
The 400 Series is designed for straightforward DIY installation. Most customers complete installation in 20-30 minutes per window using only a drill and measuring tape. We include all mounting brackets, screws, and detailed instructions with illustrated steps.
The cordless design eliminates complex cord routing, making installation even simpler. If you're comfortable with basic home improvement tasks like hanging curtain rods or picture frames, you'll have no trouble installing these shades.
Regular dusting with a vacuum's soft brush attachment every 2-3 weeks keeps your 400 shades looking fresh. For spot cleaning, use a lightly dampened microfiber cloth with mild soap—never saturate the fabric or submerge the shades in water.
The anti-static polyester fabric naturally resists dust accumulation. Avoid harsh chemical cleaners that can damage the honeycomb structure or fade the fabric. With this minimal maintenance routine, your shades will maintain their appearance and performance for many years.
Yes, the 400 Series cordless design eliminates the strangulation hazard posed by traditional corded window coverings. With no dangling cords or chains, these shades meet current child safety standards recommended by the Window Covering Safety Council.
The cordless lift mechanism operates with a simple push-pull motion on the bottom rail, making it safe for families with young children, pets, or elderly household members. This design provides peace of mind without sacrificing functionality.
The 400 Series is available in light-filtering and blackout opacity levels. Light-filtering fabric softly diffuses natural light while providing daytime privacy—you can see shapes and movement outside but details remain obscured.
Blackout fabric blocks virtually all light, making it ideal for bedrooms, nurseries, or media rooms where complete darkness is desired. Both options provide the same double-cell insulation performance; opacity choice depends on your light control and privacy needs for each specific room.
For inside-mount installation, measure the exact width of your window opening at three points (top, middle, bottom) and use the narrowest measurement. Measure length from the top of the opening to the sill. We'll deduct the necessary clearance during manufacturing.
For outside-mount installation, measure the area you want covered and add 2-3 inches to width and length for optimal light blockage. Our ordering system guides you through measurement based on your chosen mount type, and our customer support team can verify measurements before production begins.
The 400 Series is covered by our limited lifetime warranty against manufacturing defects in materials and workmanship. This includes the cellular fabric, headrail, mounting brackets, and cordless lift mechanism.
Because each shade is custom-manufactured to your specifications, we cannot accept returns on standard orders. However, if your shade arrives damaged or doesn't match your order specifications, we'll replace it at no charge. We recommend reviewing all measurements carefully before ordering to ensure proper fit.
