EPS GREY (Expanded PolyStyrene) is a type of expanded polystyrene used in construction, with the addition of graphite filler. Graphite reflects heat and improves insulation, resulting in lower thermal conductivity of the material compared to regular EPS boards by approximately 20%. This is a modern insulation material that provides more effective hermeticity of the structure by using a thinner insulation layer.
More effective – approximately 20% better insulation performance than white EPS.
Convenient – it is a lightweight material that can be easily cut into any size and shape, it does not expands.
Energy-efficient – high-quality insulation properties, high resistance to moisture and mold, and an effective solution for thermal bridges (cold spots).
Sustainable – 100% recyclable material.
