Harvia Sauna Aluminium Paper 1,25/30 M2

Harvia aluminum paper is a durable material for sauna construction that acts as a barrier to air and steam. Aluminum paper withstands high temperatures, protects wall insulation from moisture, and provides good ventilation. The width of the paper is 1,25 m and the covering area 30 m².

Tips for Installing Sauna Aluminium Paper

1. Prepare the Walls and Ceiling

• Ensure that the insulation (e.g., mineral wool) has been installed between the studs in the walls and ceiling. The aluminum foil will go on top of this insulation.
• The surface should be clean and free from debris.

2. Measure and Cut the Foil

• Measure each section of the wall or ceiling to ensure the foil fits properly.
• Cut the aluminum foil to size, leaving an overlap of at least 50mm on all edges to create seams for sealing.

3. Attach the Foil

• Start at the top of the wall or ceiling.
• Use a staple gun to attach the aluminum foil to the studs. Place staples every 200–300mm along the edges to hold the foil securely.
• Avoid pulling the foil too tight; leave it slightly loose to account for any expansion caused by heat.

4. Seal the Seams

• Overlap the edges of each foil sheet by 50mm.
• Use foil tape to seal the seams completely. This prevents moisture from penetrating the vapour barrier.

5. Ensure an Air Gap

• For optimal performance, there should be an air gap of about 20mm between the aluminum foil and the inner wooden cladding. This can be achieved by attaching battens or furring strips over the foil before installing the cladding.

6. Inspect for Gaps

• Check the entire installation for any gaps or holes where moisture or heat could escape. Patch these areas with foil tape.

7. Install the Wooden Cladding

• Once the aluminum foil is securely in place, you can proceed to install timber cladding over the foil.

Key Features: 

• Water Vapour Impermeability: Effectively blocks water vapour, crucial in high humidity areas, to protect structural and insulation materials.
• High-Quality Material: Made from top-grade domestic virgin cartonboard, ensuring durability and consistent performance.
• Aluminium and Polyethylene Coating: This dual coating enhances the paper’s moisture-resistant properties and contributes to its overall thermal efficiency.
• Optimal Installation Orientation: It’s installed with the aluminium-coated side facing the sauna’s interior, aligning with the point of highest moisture pressure for maximum effectiveness.
• Overlap and Sealing Requirement: For comprehensive protection, the paper should be overlapped sufficiently and sealed with tape.
• Versatile Application: While ideal for saunas, its properties also suit other high-moisture environments needing vapour barriers.
• Eco-Friendly Choice: Reflecting a commitment to sustainability, this product aligns with eco-conscious construction practices.
