## Long description

Kotar KR 75/L-W – 1G system board with EPS 150/30 mm is a prefabricated construction panel intended for building envelope and façade applications. The product integrates a structural board layer bonded to a 150/30 mm expanded polystyrene (EPS) core, delivering thermal insulation together with a stable mounting surface for external cladding, renders or finish layers. The panel is designed for use in new external wall assemblies, renovation work and energy-efficiency upgrades where consistent insulation performance and an even substrate are required.
Advantages
The system board offers a combination of mechanical support and thermal resistance in a single element, reducing on-site handling and installation time compared with separate insulation and backing layers. Its EPS core provides low thermal conductivity while the structural board layer ensures a flat, secure base for attaching finishes. The prefabricated nature of the panel promotes predictable performance, repeatable dimensional accuracy and simplified logistics for façade installation.
Suitable for
 External wall insulation in newbuild residential and commercial projects
 Façade refurbishment and renovation where existing walls require additional thermal insulation
 Energy-efficiency upgrades to meet thermal performance standards
 Applications requiring a ready-to-finish substrate for render, cladding or ventilated façades
Key specifications
 Construction: structural board layer bonded to expanded polystyrene core
 Insulation thickness: EPS 150/30 mm
 Function: thermal insulation and mounting substrate for external finishes
 Application area: external walls and façades, renovation projects
How to use
Install panels following project drawings and local building regulations. Position the panels on prepared wall surfaces, ensuring even contact and alignment. Fix panels mechanically or with approved adhesives according to the substrate type and wind-load requirements. Joints between panels should be closed or sealed as specified in the installation instructions to maintain thermal continuity. After fixing, apply the chosen finish system — render, cladding or ventilated façade components — following manufacturer recommendations for the finish materials.
Usage recommendations
Store panels flat and protected from prolonged exposure to sunlight and moisture before installation. Verify compatibility of adhesives, mechanical fasteners and finish systems with both the structural board and EPS core. Ensure that joint detailing and edge sealing meet local thermal bridge and airtightness requirements to achieve the intended insulation performance.
