Product description

Structural insulated panel (SIP) with OSB3 facings and a graphite EPS 100 core, designed for fast assembly, low heat loss and light weight. Graphite EPS has a lower thermal conductivity (typical λ ~0.030 W/m·K) than the white version, so you can achieve the same performance with a smaller thickness (depending on the project). The panels are produced in 2500–3000 × 1250 mm formats and structural thicknesses of 12/17/22/32 cm. (Exact details are in the technical data sheets/approvals.)

Uses

Exterior walls (17–22 cm), interior walls/partitions (12 cm)
Roof / floor slab (22–32 cm)
Residential/commercial projects where you want superior energy efficiency.

Advantages

Low λ (~0.030 W/m·K) – better insulation at the same thickness
Fast assembly – prefabrication, few joints, dedicated accessories
Low weight – low loads on the structure
Versatility – walls, roofs, floor slabs

Why choose it?

If your goal is thermal performance (lower energy bills / stricter energy standards), the graphite version gives you a clear benefit over white EPS, with the same assembly/accessory ecosystem.

Technical specifications

SIP panel types & available thicknesses

Depending on your needs, several types and thicknesses of SIP panels are available. They are used for a wide range of projects: from passive SIP houses to cabins and commercial SIP panel buildings, ensuring energy efficiency and fast assembly.

How to quickly choose the right panel:

Set the thermal performance
(budget vs. efficiency).

Choose the panel facings
(OSB3 for general use / MgO for areas with higher requirements).

Choose the core
(standard EPS 100 / graphite EPS for better insulation).
