EPS insulated panel
Stable insulation – economical – quick to install.
EPS insulated panel
The EPS panel uses an expanded polystyrene core, balancing insulation against cost. Light and quick to install, it is the economical choice for partitions, ceilings and factory cladding.
Stable thermal insulation
Optimised capital cost
Lightweight, little load on the structure
Fast to install – cost-efficient
Key advantages
Stable thermal insulation
An EPS core blocks heat well on projects that do not need deep sub-zero temperatures.
Optimised capital cost
The lowest cost of any of our panels, which suits high-volume projects.
Fast installation
Light in weight with a tongue-and-groove joint: quick to install and easier on the structure.
Durable & corrosion-resistant
High-grade coated steel that resists rust and stands up to harsh environments.
High aesthetic quality
A flat surface in a wide range of colors, easy to clean and maintain.
