Protect Your Sauna Structure from Moisture and Structural Damage
Ensure a professional, code-compliant sealing job around your chimney system with the official Harvia Vapour Barrier WHM25 (225-250mm). Specially designed for multi-layered sauna ceilings and walls, this essential component prevents water vapor and condensation from escaping the hot room and leaking into your building's structural insulation—safeguarding against rot, mold, and costly moisture decay.
Key Features
- Critical Moisture Defense: Creates a perfectly tight, dependable seal around the chimney pass-through point to block intensive steam and high-humidity vapor.
- Premium Heat-Resistant Seal: Fabricated to withstand high thermal loads directly near wood-burning stove chimney components without melting, degrades, or off-gassing.
- Adjustable Compatibility: Perfectly tailored to accommodate larger insulated chimney and smoke pipe segments with an outer diameter ranging from 225mm to 250mm.
