FINNFOAM FF-PIR ALK 100X600X2400

PIR board with double AL facing — 100 mm, full T&G, λD 0.022

FF-PIR ALK is a rigid PIR insulation board with aluminium laminate on both sides and tongue-and-groove on all edges for airtight, warm joints. Board size 600×2400 mm is easy to handle indoors; the AL facing also acts as a vapour barrier. :contentReference[oaicite:3]{index=3}
