Our new grey EPS helps you to improve thermal performance by as much as 25%


Slimmer and lighter insulation material
Because grey EPS has a thermal performance that is on average 25% better than white EPS, you can insulate slimmer or thinner with the renewed Heratekta boards. These wood wool cement boards are also lighter in weight.


One man installation of wood wool boards
The two-point fixing combined with the innovative tongue and groove connection of the Heratekta wood wool boards ensures a quick installation and a tight pattern. Installation with one man only is possible.

Grey EPS what is it?

Grey EPS is a variant of white EPS, also known as polystyrene. EPS is an abbreviation of "Expanded PolyStyrene" and consists of 98% stagnant air.

EPS hardly absorbs moisture and is resistant to most salts, acids and fats. It is environmentally sound to apply, is produced energy-efficient and is fully recyclable.

The EPS becomes grey because graphite is added during production. This means that the proportion of radiation during heat transfer is switched off afterwards. That is why grey EPS performs better than white EPS in the thermal field.

SE - self extuinguising

Heratekta panels are produced with SE quality grey EPS. The addition SE stands for Self Extinguishing. The SE quality is achieved by a fire retardant. The material stops burning when the heat source is removed.
 

Despite the positive qualities of SE quality EPS, we recommend choosing wood wool with A2 fire class in fire-resistant applications. The Tektalan A2 wood wool board with rock mineral wool is specifically developed for fire-resistant applications.
