Compact Cassette Blackout Roller Blind — YH551CB

About This Product

The Compact Cassette Blackout Roller Blind is designed for rooms where light control and a clean, tidy look matter. The aluminium compact cassette fully encloses the top mechanism, protecting the roller from dust and eliminating light gaps at the headrail for a finished appearance.
Built on a Ø28mm slotted aluminium tube, the blind stays straight and stable even at wider widths. The PVC bottom bar with fabric insert holds the 100% polyester blackout fabric firmly in place, giving a flat, neatly weighted drop. The fabric is interchangeable, so the light-blocking performance can be matched to the customer's needs.
Operation is by ball chain, and the blind is screw-fixed to the window frame or wall for a secure and durable installation. A child safety device (chain tensioner) is included as standard, meeting safety expectations for homes with young children. Optional side channels are available for customers who want to further reduce side light leakage.
Ideal for bedrooms, offices, meeting rooms and home theatre spaces where consistent darkness is preferred.

FAQ

What is the difference between "blackout" and "room darkening"?

"Blackout" generally refers to maximum light blocking (industry reference standards such as AATCC TM203 require 0.00% light transmittance to qualify as true blackout), while "room darkening" means significantly reducing light but not necessarily complete blocking. Different suppliers may define these terms differently. When sourcing, always request measured light-blocking rate data rather than relying on marketing labels alone.

What are the characteristics and differences between the three blackout fabric processes: coated, woven black yarn, and laminated film?

Coated blackout achieves light blocking by applying an acrylic or PVC foam layer on the back, with lower cost and a stiffer hand feel; long-term storage requires attention to coating adhesion. Woven blackout (black yarn) incorporates black polyester yarn during weaving, absorbing light through the yarn itself, with a softer hand feel, better breathability, and higher cost. Laminated blackout uses a TPU film bonded to the fabric, with stable blackout performance and a moderate hand feel; composite fastness must be verified. Each process has suitable applications; selection should be based on product positioning and budget.

What problems can PVC foam coating blackout roller blinds have after long-term storage?

PVC foam coating is prone to blocking (coating layers sticking together) or cracking (coating becoming brittle and peeling) after long-term storage. This is a well-known pain point of the classic PVC foam process. The severity varies by supplier formulation and storage conditions. It is recommended to avoid long-term storage of PVC foam coating products, or choose more storage-resistant alternatives such as acrylic coating.

Which is more suitable for high-end products: woven blackout (black yarn) fabric or coated blackout fabric?

Woven blackout (black yarn) fabric is generally more suitable for mid-to-high-end products. It achieves light blocking through the yarn itself without an additional coating, offering a softer hand feel, better drape, superior breathability, and no risk of coating peeling or adhesion. Coated blackout fabric has lower cost and is suitable for economy products, but may experience coating aging, hardening, or adhesion during long-term use or storage. The specific choice should be based on product positioning, target market, and budget.

What is the structure of sunscreen blackout fabric and what parameters should be confirmed when ordering?

The typical structure of sunscreen blackout fabric is: face layer of regular sunscreen fabric (70% PVC + 30% polyester), middle layer of TPU film lamination, and back layer of acrylic coating. When ordering, confirm: face layer PVC/polyester ratio, back color, and total fabric weight (face + TPU film + coating, with ±5% tolerance being a common industry acceptable range). The TPU film does not require separate parameter confirmation — only confirm that actual light-blocking performance matches the buyer's provided sample.

What are your trade terms and payment terms?

Our standard trade term is FOB Shanghai. Payment terms are typically 30% deposit by T/T after order confirmation, with the 70% balance due before shipment. We accept T/T bank transfer. For large orders, irrevocable L/C at sight can be discussed. Other trade terms (CIF, DDP) are available upon request.
