XPS Insulation Board Finnfoam FL-300 100x585x2485 mm 4.36 m² – Tongue and Groove, Strong and Moisture Resistant

Finnfoam FL-300 100x585x2485 mm is a tongue-and-groove XPS insulation board with very high compressive strength and moisture resistance. The boards are easy to install thanks to tongue-and-groove edges (FL), which provide tight and stable joints.

Each package contains 5 boards covering a total of 4.36 m². With its closed-cell structure, the boards do not absorb water, making them frost-resistant and durable even in demanding environments.

Finnfoam serves both as thermal insulation and vapor barrier/wind protection, reducing work steps and improving building economy.

Applications:

• foundation insulation and frost protection

• walls and exterior roofs

• floors and intermediate ceilings

• yard surfaces, walkways, and lightly loaded parking areas

FL-300 withstands 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: 100 mm

• Dimensions: 585 x 2485 mm (net size)

• Coverage: 4.36 m²/package
