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.

Walki Wool Alnet is an aluminium facing strengthened with a glass fibre scrim which is heat sealable to mineral wool. Mineral wool products may include boards, mats or different pipe insulations. Facing protects them from moisture and improves their fire classification. Facing also facilitates the treatment and installation of insulation products which is and important benefit. It also prevents fractures, dust building and rubbing of the insulations in narrow spaces where people move. Walki®Wool Alnet can be lacquered, preforated and preprinted.
