Product information "Sisalex 303 – Eco-friendly paper vapour barrier and airtight sealing with glass fibre mesh (75 m² roll)"
Sisalex 303 is a high-quality, three-layer, paper-based vapour control layer and airtight sealing element, specially developed for dry interior fit-out. As an eco-friendly product, it stands out thanks to its purely natural ingredients and is completely free from fungicidal treatments. This makes it the ideal choice for healthy building and living.
The membrane consists of two layers of robust kraft paper, reinforced by a glass fibre mesh insert. This combination ensures exceptional stability and tear resistance, making Sisalex 303 also excellently suited for use with blow-in insulation.

Practical installation tips
The membrane consists of two layers of robust kraft paper, reinforced by a glass fibre mesh insert. This combination ensures exceptional stability and tear resistance, making Sisalex 303 also excellently suited for use with blow-in insulation.
Data
sheet Key features and benefits:
- Purely natural: All components are of natural origin – environmentally sustainable and safe.
- Extreme strength: The integrated glass fibre mesh guarantees high tensile strength (850/800 N/5 cm) and dimensional stability.
- Optimised for blow-in installation: Thanks to its high mechanical strength, the membrane easily withstands the pressure exerted during the installation of blow-in insulation materials.
- Effective airtight sealing: Reliably protects the structure against unwanted air exchange and moisture ingress.
Technical details at a glance:
- Roll dimensions: 1.5 m x 50 m (75 m²)
- sD value: 5 m (constant water vapour transmission resistance)
- Grammage: 180 g/m² Material composition: Three-layer (2x kraft paper, 1x glass fibre mesh insert)
- Fire behaviour: Class E in accordance with EN 13 501-1
- Airtight sealing: Tested and certified as airtight in accordance with applicable standards
Installation and fixing:
Lay the Sisalex 303 on the warm side of the thermal insulation layer. The membrane is fixed to the existing substructure using staples. Final fixing is achieved by installing the interior cladding
Overlaps and sealing:
- Ensure an overlap width of at least 10 cm.
- Seal the joints to make them wind- and airtight using Ampacoll INT system adhesive tape.
- For substructures that cannot be nailed, Ampacoll DT serves as a practical installation aid.
Connections and penetrations:
- Edge junctions should be permanently sealed using Ampacoll BK 530 or Ampacoll RA.
- For penetrations such as ventilation pipes, electrical conduits, purlins or rafters, use Ampacoll BK 535 butyl rubber tape (50 mm wide).
- Important note: Pre-treat porous, dusty or rough substrates with the Ampacoll Primax primer to ensure optimum adhesion of the adhesive tapes.
