XPS Insulation Board Finnfoam FL-300 70x585x2485 mm 7.27 m² – Semi-Tongue-and-Groove, Strong and Moisture-Resistant

Finnfoam FL-300 70x585x2485 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 7.27 m². Thanks to the tongue-and-groove edges (FL), installation is smooth and the result is extra tight.

The boards are made of extruded polystyrene (XPS) with closed cells, making them water-repellent and frost-resistant. The insulation maintains its performance even in demanding conditions. Finnfoam can also replace both vapor barriers and wind protection, saving materials and labor.

Applications:

• foundation insulation and frost protection

• floors and intermediate beams

• walls and outer 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: 70 mm

• Dimensions: 585 x 2485 mm (net size)

• Coverage: 7.27 m²/package

• Tongue-and-groove edges for easy installation

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

• Material: extruded polystyrene (XPS)
