Certified wall solution for bathrooms, laundry rooms, and humid environments
At Andronor, we install these systems using TEK17-approved methods and components that follow Norwegian SINTEF recommendations for wetroom performance. Each layer is carefully selected and applied to ensure long-term durability, safety, and hygiene – avoiding issues like rot, mold, or moisture migration.
Where to Use Wetroom Gips Wall Systems – Bathrooms, Laundry Rooms, and More
Wet areas require more than just water-resistant paint – they need an integrated wall system designed to resist moisture penetration, mold growth, and condensation-related damage. This system is ideal for both full renovations and new constructions, where regulatory compliance is a must.
Best For:
- Shower and bathtub walls
- Laundry rooms and technical utility zones
- Bathrooms in apartments, cabins, or hotels
- Commercial washrooms or locker rooms
- Kitchen splash zones or damp basement areas
Wetroom Wall System Components – Framing, Membranes & Moisture-Resistant Boards
Component | Description or Option Range |
Substructure / Framework | Moisture-treated timber or galvanized steel CW/UW profiles (50–100 mm) |
Surface Layer | Mold-resistant gips boards (e.g., Gyproc Glasroc H, Norgips Humidboard, Knauf Green Gips) |
Barrier Membrane | Vapor-tight foil or plastic membrane, fully sealed to perimeter edges |
Insulation (optional) | Mineral wool for sound/thermal buffering where needed |
Fasteners & Anchoring | Corrosion-resistant screws and compatible wetroom fixings |
Sealing Products | Butyl tape, sealing compound, and edge reinforcement tapes |
All products used are CE-certified and conform to TEK17 and EN 13964/EN 13501 where applicable.
Installation Tips for Wetroom Gips Walls – Sealing, Framing, and Surface Prep
- Full-Surface Sealing: Vapor barriers must be continuous behind fixtures and tiles
- Framing Choice: Moisture-treated wood or galvanized steel preferred in all wet zones
- Penetration Protection: Pipes, sockets, or niche cutouts must be fully sealed with collars or gaskets
- Tile-Ready Surface: Surface boards compatible with tile adhesive systems
- Ventilation Coordination: Ensures system dries properly and maintains air quality
- Drainage Zones: Additional backing can be added behind wall-hung toilets or plumbing units
Andronor Tip:
Always pair this system with floor-to-wall joint sealing and pre-tiled floor prep to ensure full moisture control. For high-risk walls (e.g., behind showers), we recommend dual sealing with both foil membrane and waterproof surface board.
Wetroom Gips Wall Performance Levels – Moisture, Fire & Tiling Readiness
Wetroom-rated wall systems must perform across multiple risk zones – from splash-prone areas to steam-heavy environments. Below are tested variants:
Variant | Moisture Suitability | Fire Resistance | Tile-Ready |
Mold-Resistant Gips Only | Moderate humidity | EI30 | Yes |
Gips + Vapor Barrier | High humidity/wet zones | EI30–EI60 | Yes |
Gips + Dual Membrane Sealing (full wrap) | Continuous wet exposure | EI60+ (if insulated) | Yes (with prep) |
All classifications based on manufacturer test assemblies (Gyproc, Norgips, SINTEF approvals). Documentation available on request.
