- Thermal effect? Where? ;) Material much too fine compared to thermal or acoustic curtains. But little something hälts from determined.
- Darkens far too little in the light color
Of course, is logical and totally unexpected in classic cotton or linen curtains in white or beige. But this is a special blackout curtain.
The darkening effect here is far from sufficient to at east-south windows to sleep behind.
All relative, I know I was not dark enough. Previous curtain of a Swedish furniture company with eyelets in aubergine is much better, actually perfect, only adjusts the color no longer inzwsichen.
ERGO: bright color darkening - rather no, dark color most likely very good effect.
