Maximal sizes of roller blind (width and height) depend on used fabric type (resp. its weight and dimension possibilities).
Exact guaranteed limited sizes according to particular fabric types (according to the weight) can be found in detailed table
which is part of order form.
When using Day/Night fabrics it might cause disbalanced coiling on the tube. This is caused by different thickness of
transparent and solid stripes on fabric. This phenomenon is not reason for a claim.
By using roller blind with side rails there might be a risk that the fabric can jump off these rails under unfavorable
conditions (especially draft). The bigger the roller blind is the bigger the risk is. To decrease such risk we recommend to
use tougher fabrics. This phenomenon is not reason for a claim.
