Walki - Wool Alkraft

Walki Wool Alkraft is the solution when different mineral wool based insulations need to be easily finished with a good water vapour barrier. It is made of very strong kraft paper with an aluminium layer and polyethylene coating. Walki Wool Alkraft can be lacquered and printed. If you need a stronger version we can offer Walki®Wool Alkraft DD where we have added a glass fibre scrim.
