Product description

Structural insulated panel (SIP) with MgO (magnesium oxide) facings and a graphite EPS 100 core, designed for projects with high fire and moisture requirements while retaining superior thermal performance (typical λ ~0.030 W/m·K). The panels are manufactured in 2500–3000 × 1250 mm formats and thicknesses of 12/17/22/32 cm, allowing their use in walls as well as roofs/floor slabs. The MgO facings provide stability in humid environments and improved fire behaviour, while graphite EPS reduces energy losses compared with the white version.

Uses

Exterior walls (17–22 cm)
Interior walls/partitions in wet/technical spaces (12 cm)
Roof / floor slab (22–32 cm)
Residential or light commercial projects where you need moisture resistance and enhanced energy efficiency

Advantages

Low λ (~0.030 W/m·K) — thermal performance above the white version
MgO facings — superior moisture and fire behaviour
Fast assembly — prefabricated elements, complete accessory system
Low weight — lower loads on the structure/foundation

Why choose it?

When the project calls for high energy efficiency plus fire/moisture requirements, the MgO + graphite EPS version is the right solution: walls/roofs with low heat loss, fast assembly and clear technical documentation.

Technical specifications

Panel dimensions: 2500–3000 × 1250 mm (typical)
Available thicknesses: 12 / 17 / 22 / 32 cm
Core: graphite EPS 100 — typical λ ~0.030 W/m·K
Reaction to fire: classifications in accordance with SR EN 13501-1 (the final system class depends on layers/finishes)
Tolerances: as per the technical documentation (e.g. T2/L2/W2; flatness P5)

Assembly

Assembly carried out by a qualified team, in accordance with the assembly instructions: preparation, positioning, fixing, sealing (fasteners/tapes compatible with MgO and the panel thickness). Following the design and the construction details ensures the declared performance is achieved.

Warranty

In accordance with the manufacturer's conditions; performance is maintained provided the design and assembly are followed.

Delivery time

Confirmed in the quote depending on stock, volume and route. Typical interval: 3–7 working days.

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).
