Looking for woven honeycomb fabric built for large windows? Our 45mm woven honeycomb blind fabric is available in single cell, cell-in-cell (double cell), side-by-side double cell, and pleated structures, using a tightly woven polyester construction rather than spunlace non-woven fibers. The 45mm cell is our largest size, trapping more still air than 38mm and below while keeping the decorative woven texture buyers choose this material for — a common pick for large residential or commercial glazing. Below you'll find full specifications, structural comparisons, application guidance, and answers to the questions buyers ask most.

Woven honeycomb fabric is made by weaving polyester yarn into a defined pattern, giving it a more textured, fabric-like appearance compared to spunlace non-woven material. At 45mm, this texture is paired with our largest air pocket for the strongest thermal performance in the woven range.
Fabric texture and appearance: The visible weave pattern gives a more premium, textile-like look than the flatter surface of non-woven fabric, often preferred for decorative or higher-end interiors.
Highest insulation in the woven range: The 45mm cell holds more still air than 38mm and below, reducing heat transfer more effectively on large glazing.
Light control & privacy: Semi-blackout and light-filtering options soften incoming light while maintaining privacy; blackout performance can be added with a backing layer if full light-block is required.
Noise reduction: The larger hollow cells absorb more sound than smaller woven sizes, useful for street-facing or commercial glazing.
Crease memory: Heat-setting during manufacturing keeps the larger folds sharp and evenly spaced through repeated raise-lower cycles.
The same four structural options available in smaller cell sizes are also offered at 45mm, each suited to different performance priorities at a larger scale.
| Structure | Description | Best For |
|---|---|---|
| Single Cell | One row of hexagonal cells; slim profile, lower cost | Large residential windows on a moderate budget |
| Cell-in-Cell (Double Cell) | A smaller cell nested inside a larger cell, doubling the insulating air pockets | Commercial glazing and climates with high heating/cooling demand |
| Side-by-Side Double Cell | Two cells placed adjacently rather than nested, adding rigidity and depth | Extra-wide windows needing maximum structural stability |
| Pleated | Simple accordion fold without a hollow cell; flatter, more compact stack | Large skylights and shaped windows with limited headrail depth |

Larger cells put more stress on woven fabric during repeated use, so quality control matters even more at 45mm. Four areas separate premium woven fabric from fabric that loosens, frays, or fades quickly:
Weave density and uniformity: Premium fabric has a tight, even weave with no visible gaps or thin spots when held up to light, even across the wider surface of a 45mm cell. Loosely woven fabric stretches out of shape over time.
Crease consistency: Precise heat-setting keeps folds sharp and evenly spaced through tens of thousands of raise-lower cycles, calibrated for the larger 45mm fold depth. Lower-grade fabric loses its crease and the pleats go uneven.
Yarn dye consistency: Evenly dyed yarn avoids visible streaking or color variation across the panel width, especially noticeable on wide 45mm panels.
Edge finishing: Cut edges should be sealed cleanly with no fraying or loose threads, which is a more common failure point on woven fabric than on non-woven material.
We test and certify woven honeycomb fabric against the major international benchmarks so buyers can match documentation to their target market's regulatory requirements.

Large residential windows: Floor-to-ceiling windows and oversized glazing benefit from the stronger insulation of 45mm cell-in-cell or side-by-side woven fabric.
Commercial and office buildings: Curtain-wall glazing and large storefronts use 45mm woven fabric to manage solar heat gain with a more decorative finish than non-woven material.
Hospitality (hotels, conference centers): Large-format woven fabric with strong crease memory holds up under frequent operation while giving spaces a more premium look.
Decorative and design-led interiors: The visible weave texture suits projects where the shade fabric is part of the room's design, not just a functional cover.
Skylights and atriums: Pleated 45mm structure's flatter stack height suits large angled or shaped glazing where a bulkier cellular structure won't retract cleanly.
Need fabric samples for a large-window or commercial project? Tell us your target market, cell size preference, and whether you need semi-blackout or light-filtering fabric, and we'll send technical datasheets and physical swatches within 24 hours.
The width of each hexagonal cell when fully closed. At 45mm, this is our largest woven size, giving the highest insulation per layer in this material.
Woven fabric has a visible textile-like weave pattern; non-woven has a flatter surface and is more commonly used for foil-backed blackout.
Cell-in-cell insulates slightly better with its nested air pockets. Side-by-side offers more structural rigidity for larger windows, with similar insulation performance.
Standard fabric is semi-blackout or light-filtering. Full blackout is possible with an added backing layer — let us know if you need it.
