product details
Large cell size
The 1 1/4-inch cells perform best in energy savings and offer a sleek, minimalist aesthetic with broader, gracefully spaced pleats.
Fabric-wrapped rails
This design delivers a seamless, high-end look by perfectly matching the shade fabric, creating a fully unified aesthetic.
cordless operation
Designed with child and pet safety in mind. Simply push up or pull down from the bottom rail to position your shade exactly where you want it.
no-drill design
Designed for simplicity and ultimate wall protection. It delivers a high-tension, slip-free hold that stays securely in place without leaving a single scratch.
THICKER AIR BARRIER
The secret to exceptional thermal performance lies in the static air trapped within the honeycomb structure. Featuring a larger 1 1/4-inch cell diameter, these large-cell shades create a significantly thicker dead-air barrier than standard 9/16-inch small-cell shades.
This expanded air pocket acts as a heavy-duty insulator, drastically slowing down heat transfer through window glass. By dramatically reducing thermal bridging, these cellular shades keep indoor temperatures stable, reducing the strain on your HVAC system and delivering superior long-term energy efficiency.
Beat the Heat & Lower Cooling Costs
- Exceptional Solar Heat Defense: The expanded air buffer blocks incoming solar heat gain far more effectively, keeping rooms noticeably cooler during peak summer afternoons.
- Proactive AC Relief: Keeps indoor spaces comfortable without forcing your air conditioner to run continuously.
- Enhanced Energy Savings: Cuts summer cooling energy consumption by up to 20%–25% more than standard small-cell cellular shades.
Lock in Warmth & Reduce Heating Bills
- Maximum Draft & Cold Prevention: Minimizes radiant heat loss and cold window drafts, creating a warm, cozy microclimate indoors.
- Consistent Room Heating: Prevents warm air from escaping through chilly glass panes, reducing heating cycle frequency.
- Enhanced Energy Savings: Reduces winter heating loss and lowers heating energy consumption by up to 15%–20% more compared to smaller alternatives.

important notes
- Installation Accessories: For larger windows or outside mounts, use the provided brackets and screws for secure attachment.
- Maintenance Tips: If the shade becomes wet during use or cleaning, allow it to dry completely before raising it. Let the fabric air dry naturally to help preserve its shape and ensure long-lasting performance.
- Cleaning Tips: Regularly clean with a soft brush attachment on your vacuum. For stubborn stains, gently wipe with a solution of mild detergent and warm water. But avoid using alcohol-based cleaners or white vinegar on the fabric.
- No-Drill Installation Surfaces: The no-drill installation mechanism works best on smooth surfaces such as glass, tile, marble or metal. It is not suitable for textured walls.
- Size Recommendation: For optimal performance, we recommend using no-drill installation for fabric sizes under 3100 square inches.
