Vapour check airtightness membrane. Sd = 5m. 107g/m2

Ampatex Eco 5 Extra is a durable, lattice-reinforced, three layer vapour control and airtight membrane designed for energy efficiency and sustainable construction. With 62% renewable or post consumer recycled content (ISCC compliant), it combines high performance with eco responsibility.

Its soft flexible composition makes installation fast and simple, while the lattice reinforcement ensures stability - making it particularly suitable for injection insulation systems. 

Key Features

• Sustainable choice - 62% renewable raw materials or recycled content, ISCC certified.
• Dual function - serves as both a vapour check and airtight layer for maximum building protection.
• Lattice reinforced - strong, dimensionally stable, and ideal for injection insulation application.
• Easy to work with - soft, lightweight, and simple to cut and fix.
• Reliable airtightness - all overlaps, joints, and penetrations can be fully sealed for long term performance.

Installation Guidelines

• Install on the warm side of the insulation layer in dry interior applications.
• Lay with a 10cm overlap, smooth printed side facing into the room.
• Seal overlaps with the supplied Ampacoll Easy Tape for airtight protection.
• Use concealed staples or nails to fasten; for non-nailable substrates, apply Ampacoll DT tape.
• Fix inside linings after membrane placement.
• For edge connections, use Ampacoll BK 530 or Ampacoll RA.
• Porous or dusty surfaces should be pretreated with Ampacoll Primax.
• Penetrations (rafters, pipes, conduits, cables) should be sealed with Ampacoll BK 535 or Ampacoll Elektro / Install sleeves. 

Applications

• Internal vapour check for timber and masonry buildings.
• Airtight layer in low-energy and passive house construction.
• Ideal for injection insulation systems.
• Sustainable building and eco conscious renovations.
