Production of SIP panels

Certified in the EU. Based in Romania.

SIP Panel Structure

A Structural Insulated Panel (SIP) is a high performance element for energy efficient buildings. It consists of OSB boards and an EPS core bonded with polyurethane adhesive to provide insulation, air tightness and strength.

Energy Efficiency

Low thermal transmittance (U-value): 0.15–0.29 W/m²·K. Reduces energy consumption by up to 50% compared to conventional technologies. Minimizes thermal bridges, ensuring consistent indoor temperatures.

Rapid Construction

A 100 m² house can be assembled in just 7–10 days.
Reduce labor costs by up to 55% with fast assembly
Prefabricated panel production accelerates construction.
Modular elements and complete prefabricated modules are available

Strength and Durability

Guaranteed service life of more than 50 years.
High structural load capacity.
Resistance to earthquakes, hurricanes, and other natural disasters.
Fire resistance class REI60 (EN 1364-1:1999).

Sustainability

Made from natural and environmentally friendly materials.
Minimal production waste.
Low carbon footprint through material efficiency.
Fully compliant with green building standards.

SIP Production Process

Production takes place in a modern facility. We control every step of the process to ensure quality, precision and compliance with EU technical standards.

Gluing

Polyurethane adhesive is applied to OSB using special equipment. EPS foam is placed, followed by another adhesive layer and a top OSB sheet to form a solid SIP panel.

Pressing

The panels are placed under a hydraulic press to ensure a strong and permanent bond between the layers. This ensures structural integrity and long term durability.

Cutting

After curing, the panels are cut to the project layout. The cutting process ensures high accuracy for quick and easy installation on site.

Grooving

Panels is machined along all edges to create grooves for wooden inserts. This ensures tight, secure joints and simplifies installation using the 'spline and groove' method.

Marking

Every panel is marked according to the cutting plan. This helps streamline logistics and simplifies assembly on site by identifying each element's exact position.

Shipping

Finished panels are packed, palletised and loaded for delivery. We ensure secure packaging and on-time delivery throughout Europe, protecting products in transit.

SIP Solutions for Every Project

We manufacture SIP panels, kits, and modular systems tailored to your project requirements - from single components to complete construction solutions.

Thermal Performance

ECOPAN SIP panels offer high thermal resistance and minimal heat loss, meeting energy efficient building standards.
Precision fabrication and reduced thermal bridging ensure stable insulation over the lifetime of the building.

R-value: up to 6.3 m²·K/W
U-value: as low as 0.15 W/m²·K

We produce a wide range of panel formats to optimise energy performance.
See full R and U values in the table below (EN ISO 6946)

Sealing and Ventilation

ECOPAN SIP panels offer high acoustic performance depending on the insulation thickness, finishing layers and wall configuration.

RW 55dB in standard configuration
Up to RW 62dB with additional plasterboard
Over RW 70dB with finished fit-out

We can recommend system configurations to meet specific acoustic requirements.

Fire Resistance

The SIP system complies with EU fire safety regulations for construction products. Generally, a single layer of gypsum board provides up to 30 minutes of fire protection. In certified testing, ECOPAN SIP panels with double-sided gypsum board achieved REI 60, fire resistance in accordance with EN 1364-1:1999 and national standards.

Tested system

Load-bearing wall, 160 mm SIP + timber + double gypsum board→ Fire exposure: 62 minutes

Warranty and Lifespan

ECOPAN panels have been designed for over 50 years, as stated in the European Technical Assessment.
We offer a standard 5-year warranty on our products.

FAQ

Where are ECOPAN SIP panels manufactured?

Our production facility is located in Romania and is certified according to EU standards. All stages - from gluing to packaging - take place at our factory.

What materials do you use?

We use EGGER OSB (Austria), EPS Austrotherm/Swisspor (Austria/Switzerland) and Everad glue (France). All components comply with EU environmental and technical standards.

What are the technical properties of the panels?

The panels provide high thermal insulation (up to R=6.3), sound insulation (up to RW 70 dB), fire resistance REI 60 and a service life of more than 50 years. The standard warranty is 5 years.

ECOPAN manufactures SIP panels at a modern factory in the EU (Romania), providing a full production cycle – from material selection to packaging and delivery. We use only certified components from leading European brands: OSB EGGER (Austria), EPS insulation from Austrotherm and Swisspor, and French polyurethane adhesive Everad.

Thanks to precise automated processing, our SIP panels demonstrate high energy efficiency, stable geometry and a long service life. Each panel undergoes a multi-level quality control to ensure compliance with European construction standards ETA, CE, ISO 9001 and EN 1364.

ECOPAN’s production facilities allow us to implement projects of any scale: from individual housing to mass construction. We also manufacture SIP panels to order – with individual dimensions, cladding type and packaging.
