Achieve the Perfect Sauna Experience with Specialist Sauna Insulation And Vapour Sealing solutions

Sauna insulation helps the sauna heat up more quickly, and it protects the surrounding building materials from the sauna's heat. There are two ways to insulate a sauna: fill the stud work with rockwool and cover this with aluminium sheets to vapour seal or use specially designed foil-backed insulation board.

Vapour sealing provides the primary barrier standing between the warm, wet air trying to escape the sauna and any wood beyond it at risk from mildew, mould, and rot. Foil backed Kingspan Sauna Satu and Finnfoam polyisocyanurate (PIR) insulation board, which works as both an insulator and vapour seal and will not degrade over time.
