NEXTREMA® offers the choice of six transmission profiles, formats and colours: tinted, transparent, translucent white, translucent bluegrey, opaque grey, and opaque white. Product creativity comes as standard with NEXTREMA®, as it's available in formats as large as 1950 x 1100mm with a choice of thicknesses from 2-6 mm, 8mm is available on request.


NEXTREMA® 712-8 - Opaque Grey

NEXTREMA® 712-8 blocks all visible light and still transmits in the infrared spectrum. Compared to common zero-light radiant heaters that use a metal surface, this material enables faster heat-up times.

NEXTREMA® 724-8 - Opaque White

NEXTREMA® 724-8 hides the heating element when switched off. When the heater is switched on the material evenly diffuses the visible light over the glass-ceramic surface and still an abundance of radiant heat. Invisible
heaters blend seamlessly – eg. a bathroom is only one of many potential application ideas.

NEXTREMA® 724-3 - Transparent

NEXTREMA® 724-3 is the material of choice in situations where protection and visibility of the heating elements are needed. The material is especially suited for short wave heating applications due to its superior transmission in the relevant spectrum.

NEXTREMA® 712-3 - Tinted

NEXTREMA® 712-3 offers a black design that fits into basically every environment, hiding the heating elements when switched off. When the heater is powered on, the excellent transmission for radiant heat ensures a high heat
output at minimal glare.

NEXTREMA® 712-6 - Translucent Bluegrey

NEXTREMA® 712-6 efficiently blocks the bright glare produced by infrared heating elements while at the same time ensures a high heat output. The bluegrey design in interaction with different heating elements transforms bright glare into a pleasant red glow.
