Looking for a softer, more textured honeycomb fabric built for large windows? Our 45mm knitted yarn honeycomb blind fabric is available in single cell, cell-in-cell (double cell), side-by-side double cell, and pleated structures, made by knitting yarn into loops rather than weaving or bonding non-woven fibers. The 45mm cell is our largest knitted size, trapping more still air than 38mm and below while keeping the soft hand and flexible drape this material is chosen 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.

Knitted honeycomb fabric is made by looping yarn together rather than weaving it into a crossed pattern or bonding fibers into a non-woven sheet. At 45mm, this looped structure is paired with our largest air pocket for the strongest thermal performance in the knitted range.
Softer hand and drape: The looped knit construction gives a softer, more fabric-like feel than woven or non-woven material, with a bit of natural stretch.
Highest insulation in the knitted 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 knitted 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, despite the material's natural stretch.
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 |

Knitted fabric has different failure points than woven or non-woven material, and larger cells put more stress on the fabric during repeated use. Four areas separate premium knitted fabric from fabric that snags, sags, or fades quickly:
Loop/stitch density and uniformity: Premium fabric has tight, even loops with no visible gaps or loose stitches when held up to light, even across the wider surface of a 45mm cell. Loosely knitted fabric stretches out of shape and loses its crease over time.
Snag and pull resistance: Because knitted fabric is looped rather than woven, a snagged loop can run or ladder if the yarn isn't finished correctly. Quality fabric resists pulling and holds its structure if lightly caught.
Crease consistency: Precise heat-setting keeps folds even and stable through tens of thousands of raise-lower cycles, calibrated for the larger 45mm fold depth. This matters more on knitted fabric given its natural stretch.
Edge finishing: Cut edges should be sealed or bound cleanly to prevent unraveling, a more common failure point on knitted fabric than on woven or non-woven material.
We test and certify knitted yarn 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 knitted fabric.
Commercial and office buildings: Curtain-wall glazing and large storefronts use 45mm knitted fabric to manage solar heat gain with a softer, more tactile finish than woven or non-woven material.
Hospitality (hotels, conference centers): Large-format knitted fabric with strong crease memory holds up under frequent operation while giving spaces a softer, more premium feel.
Soft-interior and textile-forward designs: The knitted texture suits projects aiming for a softer, more tactile fabric look as part of the room's design.
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.
Fabric made by looping yarn together rather than weaving or bonding non-woven fibers, giving a softer feel and slight natural stretch.
Knitted fabric can run if a loop is snagged, but quality fabric with proper finishing resists pulling and holds its structure under normal use.
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.
