Finnish-made Arvo and Paavo aluminium vapour barrier papers are reliable moisture barriers for new sauna construction and renovation. Both products are CE-marked according to EN 13984 and designed for use in sauna walls and ceilings.
Vapour barrier
Vapour barrier
The aluminium surface reflects heat back towards the sauna room, while the vapour barrier protects insulation and structures from moisture. Paavo is a practical choice for standard sauna projects, while Arvo offers higher vapour tightness for more demanding professional use.
All seams, joints and penetrations should be sealed with heat-resistant Sitko aluminium tape to create a complete vapour barrier system.

Sitko aluminium tape
Sitko aluminium tape is used to seal seams, joints and penetrations in aluminium vapour barrier systems. Together with Paavo and Arvo aluminium papers, it helps create a continuous and reliable vapour barrier for sauna walls and ceilings.
The tape is heat-resistant up to +140 °C, making it suitable for demanding sauna conditions. It has a strong adhesive and an aluminium surface that bonds well with aluminium vapour barrier papers.
Sitko aluminium tape is available in 5 cm and 10 cm wide rolls, allowing installers to choose the right width for different sealing needs. The 5 cm roll is practical for standard seams and overlaps, while the 10 cm roll is useful for wider joints, corners and more demanding sealing areas.
