Vapour-insulation roof foil
SILVER N
The Eurovent SILVER N, vapour-insulation roof foil. Made of coated polymerfabricon bothsides with an impregnating and strengthening layer, which ensures extremely high tear resistance of the product.Used as avapour-barrier foil in building partitions, roofs, walls, ceilings, etc.
Advantages
- Vapour insulation
- Tear resistance
- Tear resistanceFast and easy application
Application and Technical Data
The reinforced Eurovent® SPECIAL N vapour barrier film is used as a vapour control layer protecting against the penetration of water vapour and moisture in ceilings, pitched and flat roofs, as well as vertical wall structures. It is installed parallel to or along the rafters, directly on the thermal insulation. During installation, the use of Eurovent® DUO or Eurovent® UNO adhesive tape is mandatory for bonding overlapping joints and sealing the connections between the film and roof structural elements.

System products
In order to ensure maximum performance of the SILVER N roof membrane, it should be used in combination with:
- Eurovent® sealing and adhesive tapes, which improve the tightness of overlaps and connections in critical roof slope areas,
- Eurovent® ventilation accessories, enabling proper air flow within the under-roof space — essential for low vapour-permeable membranes,
- Eurovent® eaves system components, ensuring proper ventilation and effective moisture discharge from the roof structure,
- Eurovent® roof clips, stabilising the roof covering and increasing the roof slope resistance to wind and snow loads.
The use of complete Eurovent® system solutions guarantees proper performance of the roof membrane, long-term protection of the structure and reliable operation of the entire roof slope for many years.
GOOD TO KNOW
Why does SILVER N have a woven structure?
The polymer fabric, coated on both sides, provides high tear resistance, distinguishing it from simpler homogeneous foils.
Does the name SILVER mean it has an aluminium reflective layer?
This should not be assumed from the name. The product is a woven vapour control foil; reflective functions are provided by products explicitly described as metallised.
Where is high mechanical resistance particularly useful?
In constructions and during work where the foil may be more exposed to stress or accidental damage.
Does SILVER N have a fixed Sd value?
Yes. It is a conventional vapour control layer rather than an active membrane with variable resistance.
Can reinforced foil be installed without tapes?
No. Mechanical strength does not replace airtight sealing of overlaps and penetrations.
