Don’t know what kind of chemicals went into manufacturing these curtains, it claims to have been made in a OEKO certified unit but after just a few weeks the curtains have started releasing a strong odour. The curtains are not exposed to direct sunlight and the room never gets hot (always below 29c). Whoever is incharge of approving AmazonBasics label just doesn’t care.
It said triple weave material, heat insulating, etc. It does nothing for heat. It blocks construction noises to some extent. So that's nice. But heat, 0 stars. It made it worse. It absorbs incoming heat and spreads it to the room making it hotter. Light blackout amount is also good.
No commercial black out curtains are 100% black out... These are about 90%...the only problem with them is getting the wrinkles out... So unless u want to use them as layering curtains.. not the best buy... But they are great for black out
Son excelentes para bloquear la luz, por mi ventana al amanecer me molestaba mucho la luz, ¡ya no más! Eso si, en cuanto a su uso para aislar calor o frio no fue de ayuda.
