To verify that our products meet high standards, we collaborate with both domestic testing laboratories and international specialized institutes. This approach allows us to guarantee our customers safety and quality, confirmed by independent experts.
Below are the results of the fabric screen studies used in Wellsun blinds. The research was conducted by the Saxon Textile Research Institute (STFI, Germany) in three areas:
- Remission and transmission in the visible light range in accordance with DIN EN 410: 2011-04 (DIN EN 14500: 2008-08)
- Remission and transmission in the global radiation range in accordance with DIN EN 410: 2011-04 (DIN EN 14500: 2008-08)
- Measurement of translucent areas (openings) of fabric structure occurs in accordance with test method PM 20. The relation of openings to the total area defines the «openness factor» according to ASHRAE Fundamentals: 2001, p. 30.49. Total measured area contains thread material area and openings.
