TargoVARIVAP GS is a high-performance variable vapour control membrane reinforced with glass fibre mesh
For controlled vapour diffusion in roof and wall constructions. Thanks to the VARIVAP effect, the membrane adapts its diffusion resistance to the ambient humidity.
- Winter (condensation period): higher Sd value, reduces moisture penetration into the construction
- Summer (evaporation period): lower Sd value, stored moisture can dry out quickly and safely
The TargoVARIVAP GS version features mesh-reinforced PP nonwoven fabric and is therefore also suitable for blown-in insulation materials.
Installation instructions
For a permanently functional construction, airtight installation is essential. The membrane must be installed without wrinkles and mechanically secured, for example by stapling.
Basic installation rules (interior):
- Install parallel to the eaves or rafters; when installing along rafters, overlap on the rafter
- Smooth side facing inwards, overlap at least 10 cm
- Seal overlaps, connections and penetrations airtight using products from the Targo adhesive system
Sealing / bonding (recommended system):
- Seal overlaps airtight with TargoRAPID
- Make connections using TargoFIX SK, a permanently elastic cartridge adhesive
- Seal penetrations, such as pipes or ventilation ducts, with TargoFlex
- For exterior applications and details, TargoBENDIX, TargoND tape and TargoFIX SK, among others, are used as part of the system
Advantages
- Humidity-variable, Sd 0.2–20 m, restricts vapour diffusion in winter and allows drying in summer
- Glass fibre mesh-reinforced construction, also suitable for blown-in insulation materials
- High back-drying capacity, increased construction safety through additional drying reserves
- Easy installation, saves time and costs
- System warranty with proven products from the Targo adhesive system
