FINNFOAM FF-PIR ALK 150x600x2400

Finnfoam PIR ALK thermal insulation board — 150 mm, 600 × 2400 mm

High-performance FF‑PIR ALK insulation boards for renovation and new building projects, suitable for roofs, walls and saunas; low thermal conductivity and diffusion‑tight aluminium facing reduce the need for separate vapor or wind barriers. Check price and buy from SityPro for full product features and benefits.

Key Benefits

Very low thermal conductivity (λdeclared 0.022 W/mK) for efficient insulation
• Thin boards deliver strong insulation performance
• Both sides covered with diffusion‑tight aluminium laminate that acts as a vapor barrier
• No separate vapor barrier required; if entire exterior uses FF‑PIR, separate wind barrier is not needed
• Fire classification of the foam: D‑s1, d0
• Standard board size (600 × 2400 mm) eases transport and handling in tight spaces
• Available in a wide thickness range (20–240 mm in 10 mm steps) to match project needs

Applications

Designed for thermal insulation where low lambda and vapor control are required; suitable for both renovation and new construction applications.

Roof insulation
• Wall insulation (external and internal assemblies)
• Sauna insulation
• Frame constructions — can be installed horizontally relative to studs
• Complete exterior insulation projects where wind barrier may be omitted

What to Consider When Choosing

Select thickness based on required thermal performance and available cavity depth
1. Consider that aluminium laminate provides a vapor control layer, so separate vapor barrier may be unnecessary
2. If the whole external construction uses FF‑PIR, a separate wind barrier can be avoided
3. Check board dimensions (600 × 2400 mm) for transport and on‑site handling limitations
4. Verify required fire classification — FF‑PIR foam class is D‑s1, d0
