XPS Insulation Board Finnfoam FL-300 80x585x2485 mm 5.81 m² – Semi-Tongue-and-Groove, Strong and Moisture-Resistant

Finnfoam FL-300 80x585x2485 mm is a tongue-and-groove XPS insulation board that combines strength, moisture resistance, and easy installation. One package contains 5 boards covering a total of 5.81 m². Thanks to the tongue-and-groove edges (FL), installation is quick and results in a tight fit.

The boards are made of extruded polystyrene (XPS) with closed cells, making them water-repellent and frost-resistant. They maintain their insulating properties even in demanding conditions. Finnfoam can also replace the need for a separate vapor barrier and wind protection, reducing both material use and labor.

Applications:

• foundation insulation and frost protection

• floors and intermediate ceilings

• walls and exterior roofs

• yard surfaces, walkways, and lightly trafficked areas

Finnfoam FL-300 has a short-term compressive strength of over 300 kPa (≈ 30,000 kg/m²) and a long-term strength of over 130 kPa (≈ 13 t/m²).

Features:

• Thickness: 80 mm

• Dimensions: 585 x 2485 mm (net size)

• Coverage: 5.81 m²/package

• Tongue-and-groove edges for easy installation

• Compressive strength: 300 kPa (short-term), 130 kPa (long-term)

• Material: extruded polystyrene (XPS)

• Water- and frost-resistant
