XPS Insulation Board Finnfoam FL-300 50x585x2485 mm 7.27 m² – Tongue and Groove, Strong and Moisture Resistant

Finnfoam FL-300 50x585x2485 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 tighter and the boards are easier to join.

Made of extruded polystyrene (XPS) with closed cells, the board retains its insulating properties even in demanding environments. Finnfoam can be used both as thermal insulation and as structural reinforcement. In many constructions, Finnfoam also replaces the need for a separate vapor barrier or wind protection, saving both time and materials.

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).
