What They Are
These are vertical blind fabric slats (also called louvres) where the bottom weight is sealed inside the fabric itself, rather than hanging externally.
Instead of using:
- Visible plastic or metal bottom weights
- Bottom link chains joining each slat
…the weight is welded into the fabric pocket during manufacturing, becoming invisible and permanently fixed.

How They’re Made
- The manufacturing process forms a small pocket at the bottom of each fabric slat.
- A specially designed flat weight is inserted into the pocket.
- The fabric edges are ultrasonically welded, fully enclosing the weight inside the material.
- The result is a smooth, sealed lower edge with no external attachments.
