As well as long-lasting performance, NOVAtherm is totally safe. That is underlined by the fact that most New Zealanders sleep with a polyester pillow and under a polyester duvet.
Polyester is not itchy, or an irritant, so it is comfortable to install.
Because NOVAtherm and NOVAhush are heat welded, there are no worries about cancer-causing formaldehyde being released over time.
