Made-to-measure sizing for optimal coverage

Each curtain is produced based on your exact dimensions, allowing a more precise fit compared to standard sizes. This tailored approach may help improve both visual consistency and insulation efficiency, especially across larger surfaces.

Available sizing options

Standard fabric width: approx. 140 cm (±2 cm)
Custom height: made according to your requested length

Accurate sizing reduces gaps around the edges, which can play an important role in how effectively the curtain performs. This is particularly relevant for full-height installations, wide openings, or door areas where consistent coverage supports better thermal results.
