Specifications in 048863
Lutron document 048863 prints 25 values in the groups the document uses, each with the document's unit. The page link beside each group opens the PDF where the group starts.
- Scope
- Roller shades across manufacturers; examples not specific to Lutron products
- Variables
- Shade height and width; fabric aesthetics and material composition; environmental lighting
Un-flatness
PDF page 2 of 048863, opens in a new tab- Where it shows
- Along the shade height; most visible fully extended
- Exaggerated by
- Fabric color; viewing angle; lighting conditions
- Remedies
- Larger tube diameter; batten; two shades instead of one
- Further guidance
- Lutron Application Note 15
Waves and Vs
PDF page 2 of 048863, opens in a new tab- Cause
- Tube deflection between end brackets under shade weight; tube nearer the hembar mid-width
Baggy Corners
PDF page 2 of 048863, opens in a new tab- Cause
- Uneven tension from fabric manufacturing or shade assembly
- Result
- Excess fabric on one or both sides
Packaging Impressions / Indentations
PDF page 3 of 048863, opens in a new tab- Cause
- Folds during handling; hembar or packaging pressing on the stored roll
- Outlook
- Typical creases likely to flatten over time, varying by fabric; damage creases may not
Cupping / Edge Curl
PDF page 3 of 048863, opens in a new tab- Direction
- Towards the window or the room
- Typical for
- Railroaded shades; non-railroaded blackout fabrics with coating tension variation
- Risk factor
- High ratio of height to width
- Where and why
- Above the bottom bar; uneven tension across the width
Telescoping
PDF page 4 of 048863, opens in a new tab- Causes
- Fabric thickness variation; fabric mounting; installation levelness; interference; fabric damage; debris
- Risk factor
- Tall, narrow shades (high aspect ratio)
- Field fix
- Lutron Application Note 14
- Cause
- Uneven tension in yarn and weave
- Effect
- Hembar out of square with the window frame when closed
- More frequent with
- Horizontal decorative fabrics mixing yarn sizes and textures
- Causes
- Improper handling; telescoping damage; rubbing on obstructions such as doors
- Fiberglass fabrics
- Some fray natural to the construction; more visible on dark colors
- Remedy
- Trim and/or remove the interference; Application Note 411 (P/N 048411)
- Where it appears
- Sheers at welded seams or hembars; sheer in front of certain bug screens; layered sheers in a dual shade
Facts Lutron states in 048863
The values Lutron document 048863 states, as published:
- Scope
- General reference for roller shades across manufacturers, not specific to Lutron products
- Variables
- Shade height and width
- Fabric aesthetics and material composition
- Environmental lighting
- What makes un-flatness show
- Runs along the shade height and shows most when fully extended, exaggerated by fabric coloring, viewing angle and room lighting
- Un-flatness remedies
- Increase the tube diameter
- Add a batten, or split one shade into two
- Lutron Application Note 15 covers designing flatter shades
- Waves and Vs cause
- Tube deflection between the end brackets under the shade's weight, bringing the tube nearer the hembar mid-width
- Baggy corners
- Inverse of waves and Vs: uneven tension from fabric manufacture or assembly leaves excess fabric on one or both sides
- Packaging creases
- Ordinary creases from handling or packaging usually flatten with time, depending on the fabric, while significant damage creases may not
- Cupping and edge curl
- Typical for railroaded shades
- Also non-railroaded blackout fabrics, from fabric-to-coating tension
- Tall, narrow shades carry the highest risk
- Puckering
- Appears just above the bottom bar when fabric tension is uneven across the shade width
- Telescoping
- One side rolls up faster than the other
- Causes: fabric thickness variation, mounting, levelness, interference, damage, debris
- More prevalent on tall, narrow shades
- Lutron Application Note 14 covers the field fix
- Twisting
- Cause: uneven tension in yarn and weave
- Effect: hembar out of square with the window frame when closed
- More frequent with horizontal decorative fabrics mixing yarn sizes
- Edge fray
- Causes: careless handling or telescoping damage
- Rubbing against obstructions such as doors
- Fiberglass fabrics show some natural fray, more visible on dark-colored fabrics
- Trimming or removing the interference resolves most cases
- Application Note 411 (048411) gives details
- Moiré
- Sheer fabrics at welded seams or hembars
- A sheer in front of certain bug screens
- Layered sheers in a dual shade
- Risk call-outs on quotes
- Lutron quotes often flag designs at risk of un-flatness or cupping, and fabrics prone to edge fray or moiré
Questions about document 048863
The answers come from Lutron document 048863 and New Way's record of it.
What is Lutron document 048863?
Lutron's five-page Application Note 863, dated May 2026 at revision A, on roller shade fabric appearance across manufacturers.
Which revision of 048863 is current?
Rev A, dated May 2026, is the revision Lutron publishes. New Way checked it against assets.lutron.com on 16 October 2026.
Which roller shades does 048863 cover?
Lutron Sivoia QS roller shades. Lutron document 048863 refers readers to document 048411.
How can un-flatness be reduced at the design stage?
Lutron document 048863 suggests a larger tube diameter, adding a batten, or splitting one shade into two. Lutron document 048863 points to Application Note 15 for designing flatter shades.
Which shade proportions carry the highest aesthetic risk?
Lutron document 048863 links cupping and telescoping to a high height-to-width ratio, so tall, narrow shades carry the most risk. Lutron quotes often call out the designs at highest risk of un-flatness and cupping.
Why does a roller shade show waves or Vs in the middle?
Lutron document 048863 explains end brackets alone hold a roller shade, so the tube can deflect under the shade's weight. When the tube comes closer to the hembar in the middle, fabric tension becomes uneven and ripples appear.
What causes telescoping, and where is the fix described?
Lutron document 048863 defines telescoping as one side rolling up faster than the other. Lutron refers the field fix to Application Note 14.
- Fabric thickness variation and fabric mounting
- Installation levelness and interference
- Fabric damage, or debris during motion or handling
Do creases from packaging go away?
Lutron document 048863 expects ordinary creases from handling or packaging to flatten with time, how long depending on the fabric. Lutron document 048863 warns that significant creases from accidental damage may not flatten out.
